XML docs with BLOB

I know it is possible to save an XML document into a BLOB field. However, can anyone tell me if it is possible to pass a BLOB in an XML document. What I mean is can I have an XML document structured as follows? Is so, where can I find the syntax. We receive XML orders via XSQL page and would like to store this data in the DB.
<xml version="1.0">
<books>
<book>
<isbn>032541251</isbn>
<title>How to Program in XML</title>
<cover>****.jpg file with picture of book that can be store in BLOB ****</cover>
<exceprt>****.PDF or MS Word .DOC of prelude for example****</except>
</book>
</books>
</xml>
Any help would be appreciated

Has anybody tried creating and validating a XML doc with XML Schema?

Hi,
Has anybody tried creating and validating a XML doc with XML Schema?

With XMLBeans, an XML document may be created from and validated with an XML schema.

XML upload (with BLOBs) failed

I want to import XML data (with BLOBS) from a APEX-2.0 XML data download.
The upload works fine on another Server having APEX2.0 installed.
Installing on XE results in: XML load error.
Using an XML data export without BLOB works fine.
Any ideas?

sorry, first reply write error
had already looked for language-problems, but there are not:
export from htmldb.oracle.com(APEX2.0)->
NLS_DATABASE_Parameters: AMERICAN_AMERICA.AL32UTF8
atabase is
import in XE(APEX2.1)->
NLS_DATABASE_Parameters: AMERICAN_AMERICA.AL32UTF8
NLS_LANG: AMERICAN_AMERICA.AL32UTF8
"XML load error" occurs only with the BLOB inside, if I export the table data without the blob column, it works.
Importing in an APEX2.0 EE-environment (even if is WE8MSWIN1252 database, not UTF8 database)

Still problems serializing xml-docs with xml-parser for java v2.0.2.7

Hi !
I'm using the Oracle XML Parser 2.0.2.7.0 and get some problems when serializing the XMLDocument.
In one class (DOMOut) I parse a xml-file with the oracle.xml.parser.v2.DOMParser, then obtain the XMLDocument and write it to System.out
In another class (DOMIn) I fetch the XMLDocument from System.in, search for a given Element and print it's TextValue (if existing) to System.out
That is where the error occurs.
I get the XMLDocument from System.in but the returning NodeList from doc.getElementsByTagName() is empty. [nl.getLength()==0] even if it shouldn't be.
Look at this code and output:
[DOMOut]
DOMParser parser = new DOMParser();
parser.parse(url);
XMLDocument doc = (XMLDocument)parser.getDocument();
ObjectOutputStream out = new ObjectOutputStream(System.out);
out.writeObject(doc); out.flush();
[DOMIn]
ObjectInputStream in = new ObjectInputStream(System.in);
XMLDocument doc = (XMLDocument)in.readObject();
doc.print(System.out);
NodeList nl = doc.getElementsByTagName("Name");
System.out.println("Length of NodeList: "+nl.getLength());
if (nl.getLength()==0)
System.out.println(argv[0] + ": not in this document!");
else {
XMLNode node = (XMLNode) nl.item(nl.getLength()-1);
System.out.println(node.getNodeName() + ": " + (node.getFirstChild()).getNodeValue());
This is the relevant code.
I javac both classes and then do this:
java DOMOut xmltestfile.xml > xx
java DOMIn Name < xx
And get this as output:
<?xml version = '1.0'?>
<!DOCTYPE course [
<!ELEMENT course (Name,Dept,Instructor,Student)>
<!ELEMENT Name ((#PCDATA)*)*>
<!ELEMENT Dept ((#PCDATA)*)*>
<!ELEMENT Instructor (Name)>
<!ELEMENT Student (Name)*>
]>
<course>
<Name>Calculus</Name>
<Dept>Math</Dept>
<Instructor>
<Name>Jim Green</Name>
</Instructor>
<Student>
<Name>Jack</Name>
<Name>Mary</Name>
<Name>Paul</Name>
</Student>
</course>
Length of NodeList: 0
Name: not in this document!
Has anyone an idea?
If I do all this stuff without serializing it works.
If I do not search for argv[0], but the string "Name" it fails.
If I do search for "*" it works fine!
I'm very confused could anybody please help me a bit??
Stefan.

Is it possible to create indexes & use them on xml docs with namespaces?

I have put an XML doc in a BDBXML container which looks like this:
*<ns1:note xmlns:ns1="http://www.testsch.org/ns">*
*<ns1:to>Eric</ns1:to>*
*<ns1:from>Brendan</ns1:from>*
*<ns1:msg>How r u?</ns1:msg>*
*</ns1:note>*
Now, I am creating an index on the element "to", as:
addIndex "ns1" "to" node-element-equality-string
Though the index has been shown as getting created using the listIndexes command, if I lookup that index with the following command:
lookupIndex node-element-equality-string "ns1" "to"
the output is:
*0 objects returned for eager index lookup 'node-element-equality-string'*
Whereas, if I do the whole procedure without the namespaces in the document & the commands, the result is fine:
*1 object returned for eager index lookup 'node-element-equality-string'*
Can someone please tell me whether using namespaces, the indexes can be created or not? If yes, how?
Thanks,
Dev
Edited by: user11871332 on Sep 7, 2009 3:53 PM

Hi Dev,
When using XML, the prefix for the namespace is really just syntactic sugar. The actual namespace in your example is "http://www.testsch.org/ns", and that's the value that you need to use when creating your index:
addIndex "http://www.testsch.org/ns" "to" node-element-equality-stringJohn

Create XML docs with hierarchy of tags and attr defined in databaste tables

Hi,
My problem is a little unique one. I want the ability to define the structure of the XML document (i.e. the hierarchy of element tags and attribute names) in the database tables. The values of tags and attributes will also be populated at runtime in tables.
Then write some generic API that reads the structure of the XML document through the database tables and spits out an XML document based on this structure and values stored in the tables.
So, basically, I want the tag names and values both to be values in the database rather than the tag names being the columns in database tables.
With this I should be able to have one procedure/function that can serve the purpose of creating XML documents with different structures by just specifying that structure in the form of database tables.
Almost all the Oracle XML utilities I read about, create XML docs based on a SQL query with tag names being columns in the database tables. Any help will be highly appreciated.
Thanks,
Monika

Which database release are you using...

Update passed in XML doc with pl/sql xmldom

Hi,
I have an xml document that is passed in through a stored procedure as CLOB. I'm trying to use the XMLParser and XMLDOM to add an additional node
The XML looks something like the following
<rowset>
<row>
<firstname>john</firstname>
</row>
<row>
<firstname>jane</firstname>
</row>
</rowset>
I need to loop through each of <mynames> nodes and then add another node <lastame> so it looks like the following
<rowset>
<row>
<firstname>john</firstname>
<lastame>smith</lastame>
</row>
<row>
<firstname>jane</firstname>
<lastame>smith</lastame>
</row>
</rowset>
I have the following code
parseClob XMLPARSER.Parser;
newNames XMLDOM.DOMDocument;
tempNode XMLDOM.DOMNode;
mye xmldom.domelement;
     item_text xmldom.DOMText;
numofrows number;
     nodeList xmldom.DOMNodeList;
     newnode xmldom.domnode;
parseClob := xmlparser.newParser;
XMLPARSER.parseClob(parseClob,names);
newNames := XMLPARSER.getDocument(parseClob);
XMLPARSER.freeParser(parseClob);
nodeList := xslprocessor.selectNodes(xmldom.makeNode(newNames), '//rowset/row');
numOfRows := xmldom.getlength(nodeList)-1;
for i in 0..numOfRows LOOP
newnode := xmldom.item(nodeList, i);
          --create the new node
mye := xmldom.createElement(newName, 'lastname');
--add it to the new node
tempNode := xmldom.appendChild(newnode, xmldom.makeNode(mye));
--update the text in the lastname
item_text := xmldom.createTextNode(newNames, 'smith');
tempNode := xmldom.appendChild(tempNode, xmldom.makeNode(item_text));
end loop;
what happens is that when i write out the newnode xml out to a buffer i see the <lastname> tag
but when i write out the newNames xml out to a buffer after the loop is finished the <lastname> tag is
missing. like it didn't update the newNames xml
I've seen lots of example on how to create an XML document with the DOM from scratch but nothing about updating
an passed in xml document. any help would be appreciated

Adding an XML doc with repeating tags

Hello,
Can anyone tell me how I take an XML document with a tag that can appear from 0-N times and map it to a database table? I am currently using a supertable and then using triggers to move data to the appropriate spot but am stuck on how to map tags that don't correspond 1-1.
My structure is like
<product>
<name>
<model>
<cost>
<feature>* (0-N)
<spec>* (0-N)
</product>
Thanks.

Generete xml doc with dtd form

Hi,
I am trying to generate xml doc based on dtd kind format.
I use following code to get my xml doc is ok based on dtd like
-----------dtd file---------------
<!ELEMENT client_data (client_job*, person*)>
<!ELEMENT client_job (job_cd, job_title?, primary_responsibilities?, grade_cd?, br_job_cd, eeo_job_group_id, effective_date?, end_date?)>

<!ATTLIST client_job deleteFlag ( Y | N ) 'N'>
<!ELEMENT job_cd (#PCDATA)>
<!ELEMENT job_title (#PCDATA)>
<!ELEMENT primary_responsibilities (#PCDATA)>
<!ELEMENT br_job_cd (#PCDATA)>
<!ELEMENT eeo_job_group_id (#PCDATA)>
-----------------end dtd--------------

qry.setRowsetTag("client_data");
qry.setRowIdAttrName(null);
// qry.useNullAttributeIndicator(true);
qry.useLowerCaseTagNames();
qry.setRowTag("client_job");
xmlDocToReturn = qry.getXMLDOM();
But if my dtd like following, i.g. has tree level, and data from multiple tables, the above code doesn't work for thes case
--------------tree level dtd----------------

XML doc with multiple namespaces

Hi,
a little stupid question...
Is it possible to get a xml file that assigns two different namespaces and I don't want to use a prefix?
example:
xml doc uses namespace xmlns:a="someuri" and xmlns:b="otheruri"
<?xml version="1.0" encoding="UTF-8"?>
<Root xmlns="someuri" xmlns:b="otheruri">
<test/>
<b:rest/>
</Root>
Some way to get prefix b out of it?
Thanx

okay, it was a stupid question...
solution:
<?xml version="1.0" encoding="UTF-8"?>
<Root xmlns="someuri" xmlns:b="otheruri">
<test/>
<rest xmlns="otheruri"/>
</Root>

Parsing an XML doc with unavailable entity (DTD)

Hi all,
I am trying to parse an XML file (web.xml) that has the following DOCTYPE in the head of the document:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN" "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app id="WebApp">When the parser starts, it will look for the DTD on the Sun site, however my work firewall blocks access to this so I get an exception when parsing.
To resolve this, I have tried to force the parser to look for a local copy of the DTD instead of the Sun site but to no avail. I still get the same error but don't know why it wont look at the local DTD.

What's the point of all that code in your EntityResolver? Would the code work just as well if the DTD didn't even exist? Then do this:public InputSource resolveEntity(String publicId, String systemId)
            return new InputSource(new StringReader(""));
        }However if you really do need to redirect to a local copy of the DTD then consider this:catch (IOException e) { }can be a real barrier to understanding in the case that an IOException is thrown. At least print a stacktrace. And: the FileReader class wants a file name in its constructor, not a URI. And in this code:String filename = uri.getSchemeSpecificPart();
filename = "file:/C:/web-app_2_3.dtd";you could write this instead:String filename = "file:/C:/web-app_2_3.dtd";which would be both shorter and easier to understand.

Applet parsing XML doc with schema

I'm trying to parse (org.apache.xerces.parsers.SAXParser) an xml document and validate it with a schema file. I'm having a little difficulty understanding how the schemaLocation (as specified in the xml file) is used by the parser. I'm trying to use a relative path....but what is it relative to???
In the xml file I specify the schemaLocation as...
xsi:schemaLocation="http://tempuri.org/DeviceDefinition.xsd ./Configuration/DeviceDefinition.xsd"
The directory structure I'm using is...
ProjectX/applet.jar
ProjectX/applet.html
ProjectX/Configuration/DeviceDefinition.xml
ProjextX/Configuration/DeviceDefinition.xsd
It's my understanding that when working with an applet the paths are a relative to the directory where the applet is installed - ProjectX in this case. Yet when I use the above defined schemaLocation I get the following error:
[Fatal Error] :0:0: File "file:///C:/Documents and Settings/dnelson/Desktop/Configuration/DeviceDefinition.xsd" not found.
It seem to be using my user.dir as a starting point for the relative path. Does anyone know why this happens???
What's the proper way to specify the schemaLocation??

xerces hates spaces in uri. so try encoding the url or get rid of the spaces

Yes, thanks Steve. I loaded ctxsrv as a daemon process and it syncs all DML every few seconds. Very nice, however, I heard ctxsrv causes a lot of index fragmentation?

Compare 2 XML Docs using JAXB

Hello List,
I use JAXB for parsing and generating XML docs. It works well after some time to learn to use it.
But now I want compare 2 xml docs.
I think the equal function is the right way, but I can't find any implementation from this function in the generated classes.
Do I look right? Is it possible to compare xml docs with JAXB?
Any other hints.
regards Dietmar

Earlier this year, I needed such a tool and finally wrote one after not being able to find one. It was a lot of work. It compared two DOM documents.
In our case, we were testing a new server implementation to create XML result files from requests from our client. I connected to a new server and an old server and sent the identical input to both. I then validated the two results using DTD's (which is all we had) and then did a brute force comparison of the two Document objects.
To make things more difficult, there were some known differences. The new version returned a few new tags and attributes in certain cases. I had to avoid using these as a reason to declare a mismatch. Also, there were timestamps and URLs returned in the files I was processing, so I had to ignore these tags as well.
Another thing to consider is that attributes do not have to be presented in any sequence, so I had to compare in a non-order-specific way. I built two HashMaps, and first looked up each old attribute in the HashMap for new attributes. If I found a match, I removed this attribute from BOTH HashMaps, when I got to the end, anything lef t over in either HashMap was an orphan.
It was a lot of work, and my solution is probably not usable outside of its environment, and I don't have permission to release the source anyway.

How to retrieve xml file from BLOB and display on browser with css/xslt

Hi All,
I am new to xml. I am storing my xml file into BLOB in database. Now in my jsp page I want to retrieve this xml file from BLOB and display in HTML/CSS/XSLT form...
Pl. guide me.. any docs..?? Logic...??
Thanks in Advance.
Sandeep Oza

Hello Sandeep!
I'm not familiar with jsp but logic should be as follows:
-in jsp page instantiate XML parser
-load specified BLOB into parser
Now you may traverse the XML tree or you might load XSL file and use transform method to transform XML according to XSL file.
I have an example where I'm selecting XML straight from relational database and then transform it using XSL into appropriate HTML output, but it's written in PSP.
You can try http://www.w3schools.com/default.asp for basics on XML, CSS, XSL. It's easy to follow with good examples.
Regards!
