SAX XML Parsing

I am very new to JAVA, but been doing JavaScript for many years. I am working in an Eclipse based editor. I have the task of reading an XML file, parsing it, using the tags as table and fields, and the values as parameters. I was successfully able to parse the XML easily with SAX, but I am having a hell of a time controling my values.
Can someone point me in the right direction on how to distinguish the tag values from the data values returned from XML? I basically need to write select statements based on these XLM files, retrieve the data from SQL, then build the output in an XML structure.
One more thing; this has to be dynamic. It needs to be able to accept random XML structures because I'll never know what is going to be imported in.
Thanks for any help.

Sorry, I've never done much with XML, so i don't know
the proper terminology. Here is a simple sample of
what I mean.
<customer>
<name>MonkeyBoy Inc</name>
<state>AZ</state>
</customer>Okay. In that example, "customer", "name", and "state" are element names. Your example shows a "customer" element. It has for children a "name" element and a "statement" element (plus some whitespace text elements). The "name" element and the "state" element both have a single child, a text node in both cases.
If you're using a SAX parser then the startElement() method gives you an element name. The characters() method gives you characters from a text node. Beware of this because it will give you the whitespace that you want to ignore, and it can give you a text node in pieces (more than one call).
The term "tag" does exist in XML but it is restricted to talking about begin tags (the <customer> bit at the start of the element) and end tags (the </customer> bit at the end of the element).

Sax XML Parser? URLDecoder.decode bad in applet? Explorer Browser jvm?

Ok, here it goes folks, I have a serious problem with Explorers jvm, I'm developing using jdk 1.3.1 to write swing applets, in anyevent little functions that I use will not work with Explorers Browser, for example, the Explorer JVM understands the Vector addElement function, but not the Vector add function? Also, It doesn't recognize the HashMap class? Ok, is there anyway to control the JVM used with Explorer? Ok, but here goes my real question?
I am writing an applet/servlet that interfaces with an oracle database. The data is returned in the form of xml. We are using the Sax XML parser interface. The parser code previously in the servlet(server side) and worked fine, but I've now moved the parsing code to the applet side, however, it seems to not want to work on the applet side. It simply hangs? I think it's a jvm issue, I've been getting many hangs with seemingly standard classes and methods, such as URLDecoder.decode(). Anyone else run into this problem using the Sax XML Parser, I have no idea what classes in the SAX Parser could be giving us a problems, or if that is even my issue. Anyone else using SAX XML parsing in an applet with Explorer 5.5. or 5.0, please let me know, if you've had issues?
Sorry, to be so long winded, and not explaining the problem very well.

First, get Sun's Java Plug-in from http://java.sun.com/products/plugin/index-1.4.html
and read up on how to make your browser use it instead.

How to use sax xml parser

hi was wondering if someone could give me an example on how to use sax
and a document handler and explain a bit

to use sax parsers you need basically to extends handlerBase wich will force you to have the 3 following methods
// imports for the sax portion of the manager,
// the portion that will permit the interpretation of
import com.sun.xml.parser.Resolver;
import org.xml.sax.*;
import org.xml.sax.helpers.ParserFactory;
public class XMLManager extends HandlerBase
private String currentElement = null; //current element name for parsing
* Default constructor
public XMLManager()
/*SAX METHODS*/
* This method is called when the SAX parser encounters an open element
* tag. Must remember which element tag was just opened (so that the
* characters(..) method can do something useful with the data that is
* read by the parser.
public void startElement(String name,AttributeList atts){
if( name.equalsIgnoreCase("MY XML TAG NAME") )
currentElement = "MY XML TAG NAME";
//then do stuff for that type of tag
* This method is called when the SAX parser encounters a close element
* tag. If the message tag is closed it means the message is valid and ready
* to be treated
public void endElement(String name){
currentElement = "";
* This method is called when the SAX parser encounters #PCDATA or CDATA.
* It is important to remember which element tag was just opened so that
* this data can be put in the right object or variable.
* Also the start index and length integer must be used to retrieve only
* a portion of the data stored in the char[]
* This section will only contain treatment for tags wich have content
* between start and end tags
public void characters(char ch[],int start,int length){
//dont read ch[] , use the
//range provided by the SAX parser.
String value = new String(ch,start ,length);
Once you have defined these 3 methods, define a method called for example parseIt(String mss) wich will contain the following code to parse the content of a string mss, a string containing xml data
try
//create an InputSource from the XML source received
StringReader r = new StringReader(mss);
InputSource is = new InputSource( r );
//create a SAX parser using SAX interfaces and classes
String parserClassName = "com.sun.xml.parser.Parser";
org.xml.sax.Parser parser = org.xml.sax.helpers.ParserFactory.makeParser(parserClassName);
//create document handler to do something useful
//with the XML document being parsed by the parser.
parser.setDocumentHandler(this);
parser.parse(is);
catch(Throwable t){System.out.println(t);t.printStackTrace();}
you can't fail with this ;)

SAX XML Parsing and Garbage Collection

I'm writing an XML parser that is running extremely slow while parsing large documents, I believe due to garbage collection. The implementation just overloads the DefaultHandler and hands that to a SAX Parser. This works fine on 2500 line XML document, taking on average a second or two, but becomes untennable when the document size is increased by a factor of 10 (often taking 5+ minutes).
I come from a C++ background and haven't dealt with automatic garbage collection at an expert level, so I'd appreciate any help. Below is a snapshot garbage collection done while a 25000 line document being parsed. It looks to me as the young objects are staying small, but older objects are going between 13M and 90M and back again. Is that what's happening? Can anyone give me leads as to what to look? Thanks in advance.

I don't think I'm creating megabytes of data, not using hashes or other expandable arrays. I've copied and pasted some code from my overriding of a DefaultHandler to give better definition to the problem.
I'm working with TPTP right now as a profiler. Are there any others you'd recommend?

SAX XML Parser problem

Hi,
I have a standard .xml file and a file called TemplateContentHandler that parses the info in the xml doc but there is an error in it. See below:
TemplateContentHandler.java
if ( strElementName.equals( TemplateConstants.RNC_Module_LDN_TU1 ) ) {
 timingUnit1TagExistInDefaultTemplateFile = true;
 System.err.println("timingUnit1TagExistInDefaultTemplateFile for TU1 == "+timingUnit1TagExistInDefaultTemplateFile);
 System.err.println("strValue for TU1 == "+strValue);
 tTemplate.setRNC_Module_LDN_TU1( strValue );
 Trace.exit();
 return;
 if ( strElementName.equals( TemplateConstants.RNC_Module_LDN_TU2 ) ) {
 timingUnit2TagExistInDefaultTemplateFile = true;
 System.err.println("timingUnit2TagExistInDefaultTemplateFile for TU2 == "+timingUnit2TagExistInDefaultTemplateFile);
 System.err.println("strValue for TU2 == "+strValue);
 tTemplate.setRNC_Module_LDN_TU2( strValue );
 Trace.exit();
 return;
 }DefaultTemplate
<RNC_Module_LDN_TU2>ManagedElement=1,Equipment=1,Subrack=MS,Slot=5,PlugInUnit=1</RNC_Module_LDN_TU2>
<RNC_Module_LDN_TU1>ManagedElement=1,Equipment=1,Subrack=MS,Slot=4,PlugInUnit=1</RNC_Module_LDN_TU1>
OutPut
root@atrcus13> timingUnit2TagExistInDefaultTemplateFile for TU2 == true
strValue for TU2 == ManagedElement=1,Equipment=1,Subrack=MS,Slot=5,PlugInUnit=1
timingUnit1TagExistInDefaultTemplateFile for TU1 == true
strValue for TU1 == ManagedElement=1,Equipment=1,Subrack=MS,SlottimingUnit1TagExistInDefaultTemplateFile for TU1 == true
strValue for TU1 == =4,PlugInUnit=1
as you can see it parses the Tag <RNC_Module_LDN_TU1> twice and splits it in2 pieces. does anyone know why this is? Also I added a dirty hack whcih works:
private int timimngUnit1Tagcounter = 0;
 private int timimngUnit2Tagcounter = 0;
if( timimngUnit1Tagcounter == 0) {
 tempTU1 = strValue;
 timimngUnit1Tagcounter++;
 Trace.message("FIRST TIME STRVALUE === "+strValue);
 tTemplate.setRNC_Module_LDN_TU1( strValue );
 else {
 Trace.message("SECOND TIME STRVALUE === " + tempTU1+strValue);
 tTemplate.setRNC_Module_LDN_TU1( tempTU1+strValue );
 timimngUnit1Tagcounter = 0;
 }but now the parser is screwing up other tags in the file; anyone have any ideas?
Thanks,
Vinnie

In which method is the code you've posted called?
Given your results, I'd suspect that it's in characters, and strValue is a string created from the character data passed in.
in that case, read
http://java.sun.com/j2se/1.4.2/docs/api/org/xml/sax/ContentHandler.html#characters(char[],%20int,%20int)
in particular
The Parser will call this method to report each chunk of character data. SAX parsers may return all contiguous character data in a single chunk, or they may split it into several chunks; however, all of the characters in any single event must come from the same external entity so that the Locator provides useful information.
The accepted pattern of use where you want to process all character data between tags in one go is to use a StringBuffer to acculmulate the characters, then process them in the following endElement or beginElement method.

Need suggestion about a fast XML parser

I have a program which needs to parse lots of XML files of sizes varing from few MBs to hundreds of MBs. It needs to parse the file in one-pass, and for which the SAX approach is best suited. I initially tried coding this program using the SAX parser provided by Java library, but it takes way-way too much time to parse the files. I then googled out Piccolo XML Parser, but it throws ArrayIndexOutOfBound exception. Furthermore, sometimes XML files could terminated prematurely.
Can you suggest any SAX XML parser for this job?

XML parsing - org.xml.sax.driver not specified

I am attempmtping to parse my first XML document and get the following excpetion when running my prog.
org.xml.sax.SAXException: System property org.xml.sax.driver not specified.
I am following the examples in the O'Reilly Java and XML book but suspect I am missing something obvious.
This is the offending line of code:
XMLReader xr = XMLReaderFactory.createXMLReader();
Any help will be appreciated.

You need to set a property for your class that invokes your SAX handler. This is the property you need to set
org.xml.sax.driver=???
Where ??? is the name of the package where your SAXparser lives.
for example, my sax driver is in:
org.xml.sax.driver=org.apache.xerces.parsers.SAXParser
(see code below)
Also, a sweet reference is Elliot Rusty Harold's "XML processing with Java", which answered all the practical questions I had -- really! And is free, online.
http://www.ibiblio.org/xml/books/xmljava/chapters/index.html
This is the code for main() where my xml handler is invoked
try
{ SpiderHandler spiderHandler = new SpiderHandler(testSpider);
 XMLReader reader = XMLReaderFactory.createXMLReader();
 reader.setContentHandler(spiderHandler);
 for (int i=4; i<args.length; i++)
 { FileReader xmlScript = new FileReader(args);
System.out.println("Input file number "+i+" named "+args[i]);
// org.xml.sax.XMLReader.parse(InputSource) interface
// see org.xml.sax.InputSource class
reader.parse(new InputSource(xmlScript));
catch(Exception e)
{ System.out.println("Error encountered in parsing from main(). \n");
e.printStackTrace();
Luck to you! XML is a joy.

XML Validation using XDK SAX/DOM Parser

Hello,
I am trying to validate xml against xsd using SAX/DOM parser, both the files are stored as CLOB column in the database. I have the requirement to report all the validation errors and based on some helpful advice/code from the earlier posts in this forum, I have used the following code to validate and report the errors.
The code works fine but for large files it never goes beyond a certain number of errors i.e. getNumMessages() (XMLParseException) never returns value greater than 100 and thus limits the output of the validation errors. Any pointers to suggest change in code or an alternative will be extremely helpful.

Thanks.

Got the answer !!!
NetBeans it self support generation of dtd file based on XML file.
Open XML file and right click on the code block. Select option to generate dtd file.
This is the drtd file it has generated..
<?xml version='1.0' encoding='UTF-8'?>

XML Parsing Error in applet

I'm trying to parse a XML dicument in an applet with the following code
String url = "myfile.xml";
org.w3c.dom.Document doc = null;
try
doc = db.parse(url);
catch (SAXException se)
System.out.println("SAX error");
and get the SAXException when the XML document contains a
non-ASCII, but ISO-8859-1 character (i.e. '�' = 0xE4)
Running the same code as Java application on the same computer,
where I also run the applet, works fine (no exception occurs).
IMHO, there should not be any difference, both applet and application
should use the same VM and, hence, the same XML parser.
Any idea why not?
I have the Sun VM coming with JRE1.4.0 installed on a PC with
windows 2000, and also got the same result with JRE1.4.2.
I checked whether the server application sends the correct xml document
by printing it to System.out (=java console of the browser, where the applet
runs, and this seems to be OK. So, my java application seems to be OK.
Is there any possibility that some settings in the browser cause this problem?
The longer I think about it, the more I'm confused.
Thanks in advance for any suggestions!

the error was set I didn't set the contentLength in the http header when sending the xml file from the servlet.
I don't really understand why this caused the type of error I experienced, but, at least, my applet works fine now.

XMl parser version problem for running struts project in jdeveloper 10.1.3

Dear All.
I am trying to run a struts (v 1.2.9) based project in Jdeveloper 10.1.3.1.0.The struts version in Jdeveloper is 1.1.
when i am trying to run the index.jsp i get an error:
org.xml.sax.SAXNotRecognizedException: http://apache.org/xml/features/validation/dynamic
I think the XML parser version is a problem.Jdeveloper has OracleXMLParser v2 and i think the XML Parser apis used in building the project is different.I have placedcustiom xml parser apis and the xerces.jar in the jdevbin/jdev/lib folder and included these jar in the bootclasspath as follows:
AddVMOption -Xbootclasspath/p:../lib/xml-apis.jar
AddVMOption -Xbootclasspath/p:../lib/xerces-2.6.2.jar
But even then the Exception persists.Is the syntax for Xbootclasspath wrong or i need to place these custom api's in some other location of jdev.
I am not being able to figure out the XMl parser problem.
Any help wud be great.
Is it that i cant run the project in jdeveloper.Just to mention the application is deployed in OC4J on the server and runs fine..But its only that i kant run it locally through jdeveloper

I am also facing the same issue on my laptop. I searched for forum but no luck.
appreciate if anybody can throw some light on this.

I have seen this error when I'm executing inside one of the (j2ee sun reference implementation) server containers (either web or ejb). I believe its caused by "something" having previously loaded the "sax 1 driver class". In my case, I think the container or server is loading the sax parser from a jar that contains a sax 1 version. If you can, ensure that nothing is loading the sax 1 parser from another jar on your system. Verify that you are loading the sax parser from a jar containing the latest version so that you get the sax 2 compliant parser. Good luck!

XML Parse Error in AWM

When expanding the Analytic Workspace in AWM I am getting the error below. I was able to create and populate the dimensions/cubes using XML Template and did not come across any errors during that process.
I tried deleting the schema and recreated the AW but still get the same error. Are there any solutions to fix this problem?

ANN: Oracle XML Parser for Java v2.0.0.1

A new maintenance release of the Oracle Parser for Java is
available for download. It has the following fixes and changes:
Bug fixes for #920536, i.e. Cannot access element attributes via
XSLT; #898423. i.e. ElementDecl's in DTDs; #774774, i.e. DOM
extensions using XSL pattern matching; #863890 i.e. SAX
IOException not thrown.
New APIs in the following new interface:
1. oracle.xml.parser.v2.NSResolver
- resolveNamespacePrefix( find the namespace definition in scope
for a given namespace prefix )
New APIs in the following classes:
1. oracle.xml.parser.v2.XMLNode
- selectNodes( Selects nodes from the tree which match the given
pattern; client can provide an NSResolver implementation to
resolve namespace prefixes in the pattern ).
2. oracle.xml.parser.v2.ElementDecl
- getParseTree( Returns the root Node of Content Model parse
tree, which could then be traversed node by node using
getFirstChild() and getLastChild(). The Node types are: PLUS,
COMMA, ASTERISK, ELEMENT, QMARK ).
This is the first beta patch release for v2.

XML Parsing in a Schedule Job (OIM 11g R1)

Hi,
I am writing a lookup recon - schedule task in OIM 11g R1 to connect to a webservice and get the lookup attribute values. Now, I am able to fetch the values in a xml format. I am facing an issue while trying to parse the xml values (tried both as a string and from a file).
I have tried using both the SAX and the DOM parser. PFA the snippet for the DOM Parser:
                    DocumentBuilderFactory builderFactory =
                        DocumentBuilderFactory.newInstance();
                    DocumentBuilder builder = null;
                    try {
                        builder = builderFactory.newDocumentBuilder();
                    } catch (ParserConfigurationException e) {
                        e.printStackTrace();
                    org.w3c.dom.Document doc =
                        (org.w3c.dom.Document)builder.parse(file);
                    System.out.println("Parsed the xml");
                    org.w3c.dom.NodeList nodes =
                        doc.getElementsByTagName("entry");
                    System.out.println("Total Profiles fetched:: " +
                                       nodes.getLength());
This is giving the nodes.getLength() as 0. Though the code runs fine in the Java Client (directly from eclipse)
The snippet for the SAX method is :
            SAXParserFactory factory = SAXParserFactory.newInstance();
            SAXParser saxParser = factory.newSAXParser();
            DefaultHandler handler = new DefaultHandler() {
                boolean bfname = false;
                boolean blname = false;
                boolean bnname = false;
                boolean bsalary = false;
                public void startElement(String uri, String localName,
                                         String qName,
                                         Attributes attributes) throws SAXException {
                    //   System.out.println("Start Element :" + qName);
                    if (qName.equalsIgnoreCase("d:Name")) {
                        blname = true;
                public void endElement(String uri, String localName,
                                       String qName) throws SAXException {
                    //     System.out.println("End Element :" + qName);
                public void characters(char[] ch, int start,
                                       int length) throws SAXException {
                    if (blname) {
                        System.out.println("d:Name : " +
                                           new String(ch, start, length));
                        blname = false;
                       saxParser.parse("home/oracle/UserProfiles.xml", handler);
This is throwing a java.net.malformedurlexception: no protocol: /home/oracle/userprofiles.xml exception. I tried to pass it as "file://home/oracle/UserProfiles.xml" but then is gives a
java.net.ConnectException: Connection refused Even this code is running fine in the Java Client when ran directly. It seems there is some weblogic configurations I am missing for the XML parsing?
Please do help, if anyone has faced any issues parsing an xml in a Schedule job. Will highly appreciate your inputs.
Thanks,
