Parsing XML with binary (Base64) elements

Can someone give me an example or point me towards some resources that discuss parsing, and rendering binary elements (.gif images, specifically) from XML to HTML? Is this a standard function of most parsers?
THANKS
ben

XML is a text format so of course it can't include binary data such as GIFs. But then so is HTML, so there doesn't seem to be much point in doing this. Your HTML would have to include a link to the GIF, rather than the GIF itself in any format, binary or otherwise. And therefore so should the XML. Given all that, it follows that parsers don't deal with whatever it is you are attempting.

How to load xml with large base64 element using sqlldr

Hi,
I am trying to load xml data onto Oracle 10gR2. I want to use standard sqlldr tool if possible.
1) I have registered my schema with succes:
- Put the 6kbytes schema into a table
- and
DECLARE
schema_txt CLOB;
BEGIN
SELECT text INTO schema_txt FROM schemas;
DBMS_XMLSCHEMA.registerschema ('uddkort.xsd', schema_txt);
END;
- Succes: I can create table like:
CREATE TABLE XmlTest OF XMLTYPE
XMLSCHEMA "uddkort.xsd"
ELEMENT "profil"
- USER_XML_TABLES shows:
TABLE_NAME,XMLSCHEMA,SCHEMA_OWNER,ELEMENT_NAME,STORAGE_TYPE
"XMLTEST","uddkort.xsd","THISE","profil","OBJECT-RELATIONAL"
2) How can I load XML data into this?
- One element of the schema is <xs:element name="billede" type="xs:base64Binary" minOccurs="0"/>
- This field in data can be 10kbytes or more
I have tried many control files - searching the net, but no luck so far.
Any suggestions?
/Claus, DK

- One element of the schema is <xs:element name="billede" type="xs:base64Binary" minOccurs="0"/>
- This field in data can be 10kbytes or moreThe default mapping in Oracle for this type is RAW(2000), so not sufficient to hold 10kB+ of data.
You'll have to annotate the schema in order to specify a mapping to BLOB datatype.
Something along those lines :
<?xml version="1.0"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:xdb="http://xmlns.oracle.com/xdb">
<xs:element name="image" xdb:defaultTable="IMAGES_TABLE">
<xs:complexType>
    <xs:sequence>
      <xs:element name="name" type="xs:string"/>
      <xs:element name="content" type="xs:base64Binary" xdb:SQLType="BLOB"/>

Problem parsing XML with schema when extracted from a jar file

I am having a problem parsing XML with a schema, both of which are extracted from a jar file. I am using using ZipFile to get InputStream objects for the appropriate ZipEntry objects in the jar file. My XML is encrypted so I decrypt it to a temporary file. I am then attempting to parse the temporary file with the schema using DocumentBuilder.parse.
I get the following exception:
org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element '<root element name>'
This was all working OK before I jarred everything (i.e. when I was using standalone files, rather than InputStreams retrieved from a jar).
I have output the retrieved XML to a file and compared it with my original source and they are identical.
I am baffled because the nature of the exception suggests that the schema has been read and parsed correctly but the XML file is not parsing against the schema.
Any suggestions?
The code is as follows:
public void open(File input) throws IOException, CSLXMLException {
    InputStream schema = ZipFileHandler.getResourceAsStream("<jar file name>", "<schema resource name>");
    DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
    DocumentBuilder builder = null;
    try {
      factory.setNamespaceAware(true);
      factory.setValidating(true);
      factory.setAttribute(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
      factory.setAttribute(JAXP_SCHEMA_SOURCE, schema);
      builder = factory.newDocumentBuilder();
      builder.setErrorHandler(new CSLXMLParseHandler());
    } catch (Exception builderException) {
      throw new CSLXMLException("Error setting up SAX: " + builderException.toString());
    Document document = null;
    try {
      document = builder.parse(input);
    } catch (SAXException parseException) {
      throw new CSLXMLException(parseException.toString());
    }

I was originally using getSystemResource, which worked fine until I jarred the application. The problem appears to be that resources returned from a jar file cannot be used in the same way as resources returned directly from the file system. You have to use the ZipFile class (or its JarFile subclass) to locate the ZipEntry in the jar file and then use ZipFile.getInputStream(ZipEntry) to convert this to an InputStream. I have seen example code where an InputStream is used for the JAXP_SCHEMA_SOURCE attribute but, for some reason, this did not work with the InputStream returned by ZipFile.getInputStream. Like you, I have also seen examples that use a URL but they appear to be URL's that point to a file not URL's that point to an entry in a jar file.
Maybe there is another way around this but writing to a file works and I set use File.deleteOnExit() to ensure things are tidied afterwards.

Problems parsing a XML with binary element

Hi,
I'm trying to parse a xml that contains an element with the type "xs:hexBinary".
The problem is that when i load a file in to the xml everything goes fine ...
no matter the size of the file (i've tested it with 6Mb file), the problem is
that when i try to parse it i got an error "java.lang.OutOfMemoryError" ... i
don't know if there is any kind of size restriction or something like that.
Any information would be gratefully considered.
Thanks a lot.
Rober.

Hi,
I found the solution in the following post:
Validate xml with DOM - no grammar found
Sep 17, 2003 10:58 AM
The solution is to add a line of code when parsing:
try {
Document document;
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setValidating(true);
factory.setNamespaceAware(true);
factory.setAttribute("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
DocumentBuilder builder = factory.newDocumentBuilder();
document = builder.parse( new File(PathToXml) );
The errors are gone !!!

               else if(qualifiedName.equals("gameID"))
                    {games.add(new Game(Integer.parseInt(current)));}
               else if(qualifiedName.equals("name"))

               else
                    {System.out.println("ERROR - Qualified Name found in xml that does not exist as databse field: " + qualifiedName);}
          catch (Exception e) {} //Ignore

          current += new String(ch, start, length);

Parsing XML with Java - seeking advice for method to pursue

Hi guys
So here's the deal: I want to parse some XML from a server, get all the data I need from it, then shunt that data to the classes that need it. However, I'm really not sure what the best way of parsing the XML is.
I've just written a class for obtaining the file, and one for building a DOM from the XML file. But looking at org.w3c.dom in the Java API documentation (see HERE) I'll have to implement shedloads of interfaces to be able to take advantage of the DOM, and I don't even know a lot about it.
So am I best just writing a simple parser based on regular expressions to get the data I want? There's about 5 attributes in the XML file that I need to get - 5 for each instance of the containing element. So I don't think it'll be hard to do with regular expressions.. plus even if I did decide to implement all the DOM interfaces, the only way I'd know how to do half the stuff is with regular expressions anyway. I mean, how else would you do it? How else could you match up Nodes according to the Strings you're using for the elements, attributes etc?
I worry that a parser using regular expressions might be too slow... I'm building this as an applet to visually display information from the server. I have nothing to support those fears, I'm just not experienced enough to know whether speed would be a problem if I chose this route... I don't think it would, but really need confirmation of that suspicion being unfounded.
Any advice would be very, very welcome, as I'm tearing my hair out at the moment, unsure what to do.

Komodo wrote:But JDOM is not in the core class libraries, is it? So if I want to create an applet embedded into a website, am I able to get people to download that as well?
Sorry, I don't know anything about applets.
Komodo wrote:Everyone's advice is appreciated, but my core question remains unanswered - would using regular expressions, considering how simple and unchanging the XML files are, be a viable option in terms of speed?
Yes! I've done more than my fair share of XML processing with REs. It's not always easy. I often wish I could just use something XPath-like. But it's certainly easy to do and would probably mean that you'd have something up and running quicker than if you spent time investigating pure XML parsing approaches.

Parsing XML with namespaces SOLVED

I'm working on a SOAP-based self-service UCCX/IPIVR script where the caller inputs an account number and I call a SOAP service and get an XML result. That part works great. I used this excellent article https://supportforums.cisco.com/document/97736/uccx-8x-really-simple-soap-client-no-custom-jar to accomplish that. With slight modification to work with the particular server/service, it works flawlessly.
My return XML file has namespaces in it with multiple sections. See attached text file with the return results.I get the same result from the SOAP call from UCCX and also from SoapUI.
First off, my Java skills are very basic at best. Also, please forgive me if I use incorrect terms when it comes to XML nomenclature.
I need to read each <b:Bill> section and parse the various elements within each section. I can use the statement "//*[local-name()='AssessmentType']" and get the AssessmentType element from the 1st <b:Bill> section but that's it. I don't know how to access the 2nd and subsequent <b:Bill> sections. I checked a number of different articles on various sites including the forums but I haven't found anything that I can understand let alone make work. I thought using QName was going to be my answer but I can't figure out how to make that work.The more I read about this the more confused I get.
I found a reference somewhere using //Bills/Bill[1]/AssessmentType to access the 1st section and //Bills/Bill[2]/AssessmentType to access the 2nd section but that returns null in both instances. If I use //a:Bills/b:Bill/b:AssessmentType I get an exception, prefix must resolve to a namespace a: exception in org.Apache.xpath.domapi.XPathStylesheetDOM3Exception.
I event tried modifying the <b:Bill> tag to <b:Bill ID="1"> and using "//*[local-name()=[@ID=1]/AssessmentType" and <Bill ID="1"> but neither of those worked. I tried removing the b: from all of the elements and tried using the same syntax but I still get null.
I'm hoping someone can point me in the right direction on how I can do what I need to do, if it's even possible. I'm sure it is, I just don't know how to go about it.
For testing, I just hard-coded the return XML string into a String variable, converted that to a document so I could use the Get XML Document Data step to parse it. The soapResponseStringModified variable is:
U"<s:Envelope xmlns:s=\"http://schemas.xmlsoap.org/soap/envelope/\"><s:Body><SOAPGetBillSummaryResponse xmlns=\"http://soap.xxx\"><SOAPGetBillSummaryResult xmlns:a=\"http://schemas.xxx\" xmlns:i=\"http://www.w3.org/2001/XMLSchema-instance\"><a:ErrorMessage i:nil=\"true\"/><a:Success>true</a:Success><a:BillCount>2</a:BillCount><a:Bills xmlns:b=\"http://schemas.xxx\"><b:Bill><b:AssessmentType>Annual</b:AssessmentType><b:BillAmount>8259.96</b:BillAmount><b:BillNumber>272818</b:BillNumber><b:BillType>Secured</b:BillType><b:IsRollover>False</b:IsRollover><b:LevyAmount>7508.24</b:LevyAmount><b:RollDate>2014</b:RollDate><b:TaxStatus>Cancelled</b:TaxStatus></b:Bill><b:Bill><b:AssessmentType>Additional</b:AssessmentType><b:BillAmount>7758.24</b:BillAmount><b:BillNumber>501340</b:BillNumber><b:BillType>Secured</b:BillType><b:IsRollover>False</b:IsRollover><b:LevyAmount>7758.24</b:LevyAmount><b:RollDate>2014</b:RollDate><b:TaxStatus>Unpaid</b:TaxStatus></b:Bill></a:Bills><a:GlobalData xmlns:b=\"http://schemas.xxx\"><b:Address>123 MAIN ST</b:Address><b:City>ANY TOWN</b:City><b:EDO>19500909</b:EDO><b:IsDelinquent>true</b:IsDelinquent><b:IsVoid>false</b:IsVoid><b:ParcelNumber>00000</b:ParcelNumber><b:State>XX</b:State><b:TaxRateArea>3016</b:TaxRateArea><b:TodaysDate>20150323</b:TodaysDate><b:Zip>00000</b:Zip></a:GlobalData><a:MainRoll>false</a:MainRoll></SOAPGetBillSummaryResult></SOAPGetBillSummaryResponse></s:Body></s:Envelope>"
Script (run in single-step mode from the IDE):
I appreciate any guidance.
Bill

It looks like I found a solution to my problem. I haven't explored this for all the possible SOAP methods I have to use but this "solution" looks encouraging.
If I do a replace() on the namespaces for a: and b: with an empty string, then replace the a:, /a:, b: and /b: with an empty string, I can use the XPath statements //Bill[1]/<FieldName>, //Bill[2]/<FieldName>, //Bill[x]/<FieldName> I can extract the data in a loop since I know the total number of bills ahead of time.
I replace xmlns:a="http://schemas.xxx" and xmlns:b="http://schemas.xxx" with "", I can extract the elements in the Bill tags.
It looks like this will solve my problem. It's not elegant but it works. When I loop through the elements, they' re updating appropriately based on the returned XML response.
I'm sure there's a more elegant way to solve this problem but based on my limited coding skills, I found this a workable solution. I don't know how to use all the various Java tools available to me so this does the job.
If someone knows the proper way to do this, I'd like to know how it's done. This will add to my toolkit and make my code easier to maintain down the road.

Parsing xml with dom4j - cannot find jar file

Hi,
I'm using Jdeveloper 10g and tomcat 5.5.9. I have a servlet which calls a java class (ParseXML.java) that trys to parse an xml string using dom4j. A snippet of ParseXML.java...
import org.dom4j.Document;
import org.dom4j.DocumentException;
import org.dom4j.io.SAXReader;
public class ParseXML {
public ParseXML(String xml) {
          this.XML_STRING = xml;
     public String parse() {
          SAXReader reader = new SAXReader();
          Document document = null;
          try {
               document = reader.read(XML_STRING);
               } catch (DocumentException de) {
               return de.getMessage();
          } catch (Exception e) {
               return e.getMessage();
               return "The xml root value is: " + document.getRootElement().getName();
} I've downloaded the dom4j 1.6.1 jar and put it on the project class path (specified in the jdev project proerties), and my code also compiles ok. But when i try to instantiate ParseXML from my servlet i get a runtime exception:
javax.servlet.ServletException: Servlet execution threw an exception
root cause
java.lang.NoClassDefFoundError: org/dom4j/DocumentException
     arcims.GetMapServlet.doPost(GetMap.java:45)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:709)
     javax.servlet.http.HttpServlet.service(HttpServlet.java:802I'm not sure if this is a class path issue or something else; i've checked and rechecked the classpath and nothing seems amiss.
Suggestions, anyone?

Question: Is it really necessary to use a
StringReader if my xml document is not saved to disk?
I get XML_STRING from a web service, convert it into
a xml document so i can manipulate/parse it, but then
i don't save the document, i just discard it. How
does my system's default character set affect string
manipulations that i do within my java app?Your system's default charset doesn't have anything to do with string manipulations, if by that you mean substrings and concatenations of strings. It is used when you convert strings to bytes and bytes to strings. If your string contains a character that can't be handled by your default charset, then converting that string to bytes will put ? in place of that character. Converting those bytes back to a string will leave the ? as is. Thus your string has been changed.
Also converting the string to bytes can have bad results, because the first thing the XML parser does is to convert the bytes back to a string, using the charset declared in the XML. If this charset is different from your system's default, then your XML may be corrupted by this process if it contains characters that are encoded differently in the two charsets. The typical example of this is European accented letters like �, which are encoded differently in ISO-8859-1 or Windows-1252 (most people's default charsets) and UTF-8 (the default XML charset).
Besides, converting the string to bytes just so it can be immediately converted back to a string is rather wasteful.

Parsing XML with VBS at a Windows Server 2008 R2

my name is Marius, and I have a little problem with my vbs script. I use this script to parse an xml File if there are errors inside. In my old environment Windows Server 2003 it would work fine.

Parsing xml with namespaces

Hi
I have to parse a xml file with 2 namespaces.
The file looks like as follows
<AA xmlns="http://XX.com/provider/C/D/E/F/2010/">
<BB xmlns="">
<Id>262</Id>
<Time>2011-03-10T13:55:00.000-06:00</Time>
<Indicator>true</Indicator>
</BB>
</AA>
i tried following 3 methods to parse this xml file but failed
PROCEDURE LOAD_XML
IS
l_clob := ' <<Above XML Content Here >>';
lv_root CONSTANT VARCHAR2(1000) := '/AA/BB'; /* Tried lv_root CONSTANT VARCHAR2(1000) := 'AA/BB' with all the three methods */
/* Method 1 */ lv_namespace constant varchar2(1000) := 'xmlns="http://XX.com/provider/C/D/E/F/2010/"';
/* Method 2 */ lv_namespace constant varchar2(1000) := 'xmlns="http://XX.com/provider/C/D/E/F/2010/" xmlns=""';
/*Method 3 */ lv_namespace constant varchar2(1000) := 'xmlns="http://XX.com/provider/C/D/E/F/2010/"/xmlns=""';
BEGIN
l_parser := dbms_xmlparser.newParser;
BEGIN
dbms_xmlparser.parseClob(l_parser, l_clob);
END;
l_doc := dbms_xmlparser.getDocument(l_parser);
-- Free resources associated with the CLOB and Parser now they are no longer needed.
dbms_xmlparser.freeParser(l_parser);
l_nl := dbms_xslprocessor.selectNodes(dbms_xmldom.makeNode(l_doc),lv_root,lv_namespaces );
FOR cur_rec IN 0 .. dbms_xmldom.getLength(l_nl) - 1 LOOP
l_n := dbms_xmldom.item(l_nl, cur_rec);
lv_rows_inserted_cnt := lv_rows_inserted_cnt + 1;
dbms_output.put_line('I am Here');
lv_rows_processed_cnt := lv_rows_inserted_cnt;
dbms_xmldom.freeDocument(l_doc);
l_clob := null;
dbms_output.put_line(lv_rows_processed_cnt||' Rows Parsed ');
END LOAD_XML ;
Every time zero rows are being parsed and it's not going into the for loop at all.
How to parse these kind of multiple namespaces (Especially default and unassigned namespaces ) ?
Thanks
Pramod

As Anton showed, you don't need namespace if you directly access target node with the descendant axis.
However, I guess it's a simplified example so if you need it in a more complex case, this will do it :
DECLARE
l_clob clob := '<AA xmlns="http://XX.com/provider/C/D/E/F/2010/">
<BB xmlns="">
<Id>262</Id>
<Time>2011-03-10T13:55:00.000-06:00</Time>
<Indicator>true</Indicator>
</BB>
</AA>';
lv_root       CONSTANT VARCHAR2(1000) := '/ns1:AA/BB/*';
lv_namespaces CONSTANT VARCHAR2(1000) := 'xmlns:ns1="http://XX.com/provider/C/D/E/F/2010/"';
l_parser dbms_xmlparser.Parser := dbms_xmlparser.newParser;
l_doc    dbms_xmldom.DOMDocument;
l_nl     dbms_xmldom.DOMNodeList;
l_n      dbms_xmldom.DOMNode;
lv_rows_inserted_cnt NUMBER := 0;
lv_rows_processed_cnt NUMBER;
BEGIN
dbms_xmlparser.parseClob(l_parser, l_clob);
l_doc := dbms_xmlparser.getDocument(l_parser);
dbms_xmlparser.freeParser(l_parser);
l_nl := dbms_xslprocessor.selectNodes(dbms_xmldom.makeNode(l_doc), lv_root, lv_namespaces);
FOR cur_rec IN 0 .. dbms_xmldom.getLength(l_nl) - 1
LOOP
   l_n := dbms_xmldom.item(l_nl, cur_rec);
   lv_rows_inserted_cnt := lv_rows_inserted_cnt + 1;
   dbms_output.put_line(dbms_xmldom.getNodeValue(dbms_xmldom.getFirstChild(l_n)));
END LOOP;
lv_rows_processed_cnt := lv_rows_inserted_cnt;
dbms_xmldom.freeDocument(l_doc);
dbms_output.put_line(lv_rows_processed_cnt||' Rows Parsed ');
END;
/If you're on version 10.2 (or +), maybe you'll find easier to use XMLTable instead :

What am I doing wrong?
Any help appreciated.

Hello,
Can u please help me in resolving this issue.
I need to parse an XML in which some tags does not contain data or there is no such tag present in an XML.
Whenever i parse such a XML i receive error-ORA-30625: method dispatch on NULL SELF Argument is disallowed.
As per my requirement - I may get values in all tags at one time and next time i may receive values of some fields only.
I have tried this:
DECLARE

v_xml XMLType;

In this the value in <name></name> tag is NULL.
Please let me know if i can parse this XML.

Parsing XML with invalid URI for DTD

When parsing an XML file (with aelfred2) I get the following error:

at gnu.xml.aelfred2.XmlParser.parseDocument(libgcj.so.7)
I'm puzzled, as I have disabled validation:
DocumentBuilderFactory domFactory = DocumentBuilderFactory.newInstance();
domFactory.setIgnoringComments(true);
domFactory.setNamespaceAware(false);
domFactory.setValidating(false);
My goal is to have the parser ignore the DOCTYPE tag and not try to find the DTD. Can someone suggest how you turn this off - apparently, setting the validation to false is not the right approach.
I'm running Java 1.4.2 on Fidora Core 5.
Thanks for suggestions!

Create an org.xml.sax.EntityResolver and apply it to your parser. The API documentation for the interface has an example of how to write one.
And no, turning of validation doesn't turn off processing of DTDs because DTDs are for things other than validation. Entity replacement, for example.

Parsing xml with microsoft VM 1.1

Hi all,
I hav an applet, compiled with -target 1.1, which makes use of XML, so I've created an extra cab-file with all the javax.xml.parser classes and all the org.w3c.dom classes in it. This applet needs to run on Microsoft-based machines (Microsoft (R) VM for Java, 5.0 Release 5.0.0.3805), and when I read the xml-file it keeps throwing java.lang.NoClassDefFoundError on
Error loading class: javax.xml.parsers.ParserConfigurationException.
That class is definitely in the extra cab-file I provide, but apparently the appletloader still can't find it. I extracted those classes from
\j2sdk1.4.2_08\jre\lib\rt.jar.
Am I right in guessing that those classes should be compiled with target 1.1 as well? Or am I missing something else? If you want to see any code, let me know.
Thanks for any help on this one,

Hi all,
I hav an applet, compiled with -target 1.1, which makes use of XML, so I've created an extra cab-file with all the javax.xml.parser classes and all the org.w3c.dom classes in it. This applet needs to run on Microsoft-based machines (Microsoft (R) VM for Java, 5.0 Release 5.0.0.3805), and when I read the xml-file it keeps throwing java.lang.NoClassDefFoundError on
Error loading class: javax.xml.parsers.ParserConfigurationException.
That class is definitely in the extra cab-file I provide, but apparently the appletloader still can't find it. I extracted those classes from
\j2sdk1.4.2_08\jre\lib\rt.jar.
Am I right in guessing that those classes should be compiled with target 1.1 as well? Or am I missing something else? If you want to see any code, let me know.
Thanks for any help on this one,
Stef

Problems whilst Parsing XML with KXML2

I have been doing a lot of reading up on the APIs of XMLPull and KXML2.
I seem to be facing a problem which can't be solved just by reading but rather the expertise of the more experienced programmers dealing with XML parsing in J2ME.
I know how long it takes to process an entire XML document, I just would like to parse certain parts of the document. For e.g. instead of reading the whole document, say I just want to read the first 7 items and subsequently, the next 7 items when the user clicks on the next page?
In other words, I wish to incorporate paging. Is it possible? Or if you have an alternative solution which will not make a user wait too long, please share it!
Can anyone help me?

I don't think that is possible. We can't make the XML
any smaller because it contains all the information I
want to display. Just that I want to display it in
pages/sections so as to reduce the load.
So I was thinking of whether it is possible to read
the first 5 <title> tags and next 5 for every page
... etcimagine that you have 20 pages so the user will have to download a 20 x 5 items xml file?
if the user stops the navigation at page 4, he will download 16 pages for nothing so that's
why i told you to separate the results...
an xml file for each page and not a huge for all !
