Installing a DOM XML Parser

Hey, I apologize for the newbie question but I suppose this is as good a place as any for it. I'm in desperate need of a DOM XML parser and have decided upon the Apache parser, "Xerces," featured here. My problem is this, every time I make a move towards installing it, I get all mixed up at the mention of my "Apache, ant and forrest" installations that I am apparently supposed to have in order for this library to work. My question is, is this library only for use in web-based applications and thus requires Apache in order to run? I ask because the application I'm working on is simply for desktop usage and the users it will be distributed to will not have Apache installations. If somebody could help me out with a quick little walk-through on the installation of this library it would be IMMENSELY appreciated.

Study up on the javax.xml.parsers API here at Sun. Next, download Xerces from Apache (xml.apache.org). Finally, take a tutorial.

DOM XML Parser in Stateless Session Bean- Not able to generate Container

I am trying to do some XML Parsing using a DOM Parser in a Stateless Session Bean. I am importing org.apache.xerces.parsers.DOMParser and trying the following statement DOMParser parser = new DOMParser();
Even though I am able to compile and generate the initial jar file. When I try to generate the container using the Weblogic Deployer GUI tool, the process keeps on going(I mean that I see the small window saying Container Generating working) and it never stops.
Any suggestions are welcome.

Many thanks ksaks for replying.
Actually day before yesterday we were able to do something like this. But then I kept this thread open only to see if experts have some good way of doing this.
What I mean is if this way is industry standards in terms of design and does it follow the most popular way how experts do it?
I am asking this as WebProjects have webcontent/web-inf directory wherein we put those xsds and property files, but we do not have anything like this in an EJB project. so was just wondering if this is the correct way of doing it or not.
I am still following this approach because I had to proceed further in my development. Confirmation would erase any other doubts on this.
Hope you find time to reply.
Kind Regards,

DOM XML Parsing...

Hi All,
I need a sample code to parse the following xml...
<EMPLOYEE>
<RECORD>
<EMPID>12</EMPID>
<EMPNAME>ROCK</EMPNAME>
</RECORD>
<RECORD>
<EMPID>13</EMPID>
<EMPNAME>PETER</EMPNAME>
</RECORD>
<RECORD>
<EMPID>14</EMPID>
<EMPNAME>JOHN</EMPNAME>
</RECORD>
</EMPLOYEE>
I need a generic parser code, to parse the records and populate into employee table.
Thanks in Advance....
Regards,
Simbhu

One way is using supplied XML function
SQL> create table my_employee ( empid number primary key, empname varchar2(50));
Table created.
SQL> insert into my_employee
2 select extractValue(column_value, '/RECORD/EMPID') EMPID, extractValue(col
umn_value, '/RECORD/EMPNAME') EMPNAME from TABLE(
3 XMLSEQUENCE(
4 EXTRACT(
5 XMLTYPE(
6 '<EMPLOYEE> <RECORD> <EMPID>12</EMPID> <EMPNAME>
ROCK</EMPNAME></RECORD><RECORD><EMPID>13</EMPID><EMPNAME>PETER</EMPNAME></RECORD
<RECORD><EMPID>14</EMPID><EMPNAME>JOHN</EMPNAME></RECORD></EMPLOYEE>'7 ),
8 '/EMPLOYEE/RECORD'
9 )
10 )
11 ) tb;
3 rows created.
SQL> select * from my_employee;
EMPID EMPNAME
12 ROCK
13 PETER
14 JOHN
Better way is if you have XSD, register it into Oracle. Oracle will create underlying tables.

I can get the Numm string using the parser by this line
elementSub5.getFirstChild().getNextSibling().getNodeName())
BUT:: I cannot get the value of that node to print out, or set it to a variable.
I really need the 101010101010101 but cannot get them. I have tried everything.

If you could post more code I could possibly help you out. Just post some code of where the problem is and I will look at it. I believe there is a getNodeValue() method and there may be a getTextContent() method or something... actually I think I ran into this problem before... you can pull the value out of the toString() method by using a substring.
I used something like this and it worked fine...
String data = node.toString();
data = data.substring(data.indexOf(":")+1, data.length()-1);
In your case perhaps you can try something like this...
String elementData = elementSub5.getFirstChild().getNextSibling().toString();
elementData = elementData.substring(elementData.indexOf(":")+1, elementData.length()-1);
That substring method may not be 100% accurate... you best bet is to just put the node to a string and by debugging the program look at what the string value is. You can then adjust the substring to grab the correct data from the XML.
You would think there is a better way to do this... but I could not find it and this way worked for me...

Installing XML Parser for PL/SQL

Hi,
I have downloaded the plxmlparser_V1_0_1.tar.gz and followed the instruction to install it. The README file said to use the loadjava to upload xmlparserv2.jar and plsql.jar in order.
When I tried to load xmlparserv2.jar using the following command
loadjava -user test/test -r -v xmlparserv2.jar
to upload the jar file into an 8i database.
After much of the uploading, I got the following error messages:

Could someone tell me how to resolve the problems? I think I have install the JServer on the database, correctly.

The JServer option is not properly installed if you're getting errors like this during loadjava.
You need to run INITJVM.SQL and INITDBJ.SQL to get the JavaVM properly installed.
Usually these are in the ./javavm subdirectory of your Oracle Home.

Since installing the latest update, Firefox will not load; it gives me the following error -- XML Parsing Error: not well formed.

since installing the latest update, Firefox first operated with some errors but now will not load at all; it gives me the following error --
XML Parsing Error: not well formed
locations chrome://browser/content/browser.xml
Line Number 1191, column 20:
utton id="back-forward-dropmarker" type="menu" chromedir="&locale.dir;"-------------------
please note that the words "utton ID" are exactly as the error message gives it; and at the end of the message there are exactly 19 hyphens.
I don't know why this faulty code is referencing things to do with "chrome"... the Chrome browser is not installed on this PC or anywhere on our network.
Also, this is not the first problem I had after clicking Firefox's prompt for the latest update. Before Firefox retreated into this error message, it was loading but running with some faults...
1. the bookmark symbol was not appearing on the right hand side of the URL line, so I had always to click on "bookmark this page", after which the bookmark symbol did appear; however I don't know if the bookmarking function worked properly.
2. the back and forward buttons were not highlighted, as if I had not come from a previous page; so once I clicked on a link to a new page I could not go back to where I came from because Fiefox thought I hadn't come from anywhere.
3. there may have been other errors, but I did not find them.
How do I reinstate my Firefox program to work properly please? do I have to download the latest version and reinstal? if so, do I have to remove the old version first? or is there a fix?
Even to write this message I have been forced to use (yuk -- I don't like to say this!!!) Internet Explorer. So please -- I need help urgently.
Thanks,

Some how I solved my problem by opening a user account and downloading Firefox 4.0 beta and installing it, I did try it, worked fine, so I did close the user account and did go back to my own account(switched user), the main page that I had problem with Firefox which would not open, I dabble click on Firefox it start working again!! I hope that solves your problem too.
firefox will not open, it gives me this cod and would not turn off, Error on switching in renew: NS_ERROR_UNEXPECTED, Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref] id: none

XML Parser Exception in Install of AIA 11.1.1.5 on SOA 11.1.1.5

I am attempting to install AIA Foundation Pack on a SOA domain and continually encounter an XML parsing exception error as the installer is attempting to install WSM security policies. Here are the key details:
AIA version = 11.1.1.5
SOA Suite = 11.1.1.5
WebLogic = 10.3.5
Operating System = Fedora14 (a home lab machine but I don't think this is an OS issue)
The error is encountered about 17 minutes into the lengthy process. Just before the error appears in the installation log, the following message appears indicating roughly what step is being performed:
[zip] Building zip: /opt/oraclemw/aia11115/aia_instances/dev1/tmp/aia_security_policies.zip
The core error messages are:
[exec] SEVERE: WSM-01605 XML parser exception
[exec] oracle.xml.parser.v2.XMLParseException: Expected 'EOF'.
[exec] at oracle.xml.parser.v2.XMLError.flushErrors1(XMLError.java:323)
The python modules being executed by the WLST scripting tool at the time of the failure are:
[exec] Problem invoking WLST - Traceback (innermost last):
[exec] File "/opt/oraclemw/aia11115/Infrastructure/Install/AID/lib/py/importpolicy.py", line 29, in ?

[exec] File "/opt/oraclemw/oracle_common/common/wlst/lib/ora_util.py", line 51, in raiseScriptingException
[exec] OracleScriptingException: None
Finally, the outer XML files being used as input for the deployer that seems to be running at the time are:
/opt/oraclemw/aia11115/Infrastructure/Install/AID/AIAExecuteDriver.xml
with references to lines 221 and 64.
The problem occurs whether I try to use Java JDK 16.0.20 or JRockit R28.2.0 as the JRE when running the AIA installer. (The WebLogic domain is configured to use JRockit).
Any suggestions? Is there a library conflict being picked up between different releases of XercesImpl? I would hope there isn't actually a bad XML file in the AIA artifacts or WSM (Web Service Management) policies being deployed.

HI
How this issue was resolved? Please explain in detail. I am facing the same issue.

Hello
I am getting java.lang.ClassCastException: oracle.xml.parser.v2.XMLText cannot be cast to org.w3c.dom.Element error. This code is in java which is present in java embedding.
The SOA is parsing the xml in java code using oracle.xml.parser.v2 . This wont be a problem if the SOA uses default w3c DOM parser. How do i force SOA to use w3c DOM parser.
Is there any thing i can do with class loading?
Kindly help.

Can you paste your java code here ? I assume, you must have tried type-casting.

Installing XML Parser for Java v2

I downloaded Oracle XML Parser for Java v2 and looked in the doc directory of the unzipped files but couldn't find any doc about installation. Can anyone point me in the right the direction or tell me how to install and use it to convert XML files stored in the files system to HTML output using XSL stylesheet. Thanks

There is no installation involved beyond including the xmlparserv2.jar in your CLASSPATH. Take a look in the sample directory where we have included sample code and instructions on their use.
Addiaitonal HTML conversion samples are included with the XSQL Servlet download.

XML Parser for Java v2. Applying XSLT to DOM tree

I encountered pretty weird behavior of XML Parser for Java v2.
While applying XSLT to XML document created in memory using DOM
interface I couldn't access element attributes. For example,
given the XML document:
<root>
<Item ID="00001">Value of Item 00001</Item>
<Item ID="00002">Value of Item 00002</Item>
</root>
and XSLT:
<xsl:template match="/">
<HTML>
<HEAD>
<TITLE>XSLT Test</TITLE>
</HEAD>
<BODY>
<xsl:for-each select="/Error">
<H1>Error</H1><xsl:value-of select="."/>
</xsl:for-each>
<TABLE border="0" cellspacing="0" cellpadding="2">
<TBODY>
<xsl:for-each select="/root">
<TR>
<TH style="background-color:khaki">
<xsl:text>Attribute</xsl:text>
</TH>
<TH style="background-color:khaki">
<xsl:text>Value</xsl:text>
</TH>
</TR>
<xsl:for-each select="Item">
<TR>
<TD><xsl:value-of select="@ID"/></TD>
<TD><xsl:value-of select="."/></TD>
</TR>
</xsl:for-each>
</xsl:for-each>
</TBODY>
</TABLE>
</BODY>
</HTML>
</xsl:template>
If I build DOM tree by parsing XML file the resulting HTML
document after applying XSLT will display
Attribute Value
00001 Value of Item 00001
00002 Value of Item 00002
But if I build DOM tree using following code:
XMLDocument xDoc = new XMLDocument();
Element root = xDoc.createElement( "root" );
xDoc.appendChild( root );
Element elem = xDoc.createElement( "Item" );
elem.setAttribute( "ID", "00001" );
root.appendChild( elem ).
appendChild( xDoc.createTextNode( "Value of Item 00001" ) );
elem = xDoc.createElement( "Item" );
elem.setAttribute( "ID", "00002" );
root.appendChild( elem )
.appendChild( xDoc.createTextNode( "Value of Item 00002" ) );
the same XSLT will produce the following HTML output:
Attribute Value
Value of Item 00001
Value of Item 00002
So the value for the ID attribute is not displayed. At the same
time I can access this attribute using DOM interface. For
example, following code
NodeList nList = xDoc.getElementsByTagName( "Item" );
Element e;
for( int i = 0; i < nList.getLength(); i++ )
e = (Element)nList.item( i );
System.out.println( "ID: " + e.getAttribute( "ID" ) );
produces an output
ID: 00001
ID: 00002
Here is the code for applying XSLT to DOM tree:
DOMParser parser = new DOMParser();
parser.parse( new FileInputStream( "test.xsl" ) );
XMLDocument xsldoc = parser.getDocument();
XSLStylesheet xsl = new XSLStylesheet( xsldoc, createURL( "" ) );
XMLDocument out = new XMLDocument();
out.appendChild( new XSLProcessor().processXSL(xsl, xDoc) );
out.print( new FileOutputStream( "test.html" ) );

XML validation using XDK DOM/SAX 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.

I have the same question. I have an external DTD. I wish to parse an xml file using XMLParser.xmlparse. If I first call XMLParser.xmlparseDTD and then call xmlparse with the XML_FLAG_VALIDATE will the xml automatically be validated against the previously parsed DTD? There is no DOCTYPE declaration in the xml file.
The demo code on OTN for Java is great but has no relation to the code you would use in C++ (no set functions in C++).

Problem casting org.w3c.dom.Document to oracle.xml.parser.v2.XMLDocument

I have the following problem:
I get my xml-documents as an XMLType from the database and want to compare these using the supplied Oracle class oracle.xml.differ.XMLDiff (i use the java version supplied with Oracle 9i r2).
XMLType.getDOM() returns the xml-document as a org.w3c.dom.Document,
what i need for oracle.xml.differ.XMLDiff is a oracle.xml.parser.v2.XMLDocument.
How can i cast/convert between these two formats?
thanks!
p.s. cross-posting with Re: Casting/Converting XMLType to XMLDocument? (but i think this forum is more relevant).

Hi,
thanks for the suggestion: i have written the code shown below. It results in a casting error.
As far as i know, i don't use a oracle.xdb.dom.XDBDocument, i only use a oracle.xdb.XMLType as the input parameter for my conversion-method:
any new suggestions ???
p.s. the second method which is commented does work, but is a bit verbose.
   private static oracle.xml.parser.v2.XMLDocument convert2XMLDocument(XMLType xml) {
     // simple version (should work according to tech. doc. 9i r2/ 10g r1 database)
     oracle.xml.parser.v2.XMLDocument doc = null;
     try {
        // n.b. probleem is dat XMLType.getDOM() een w3c.Document object teruggeeft ipv een oracle.XMLDocument.
        System.out.println("convert2XMLDocument(): casting w3c.Document naar oracle.XMLDocument.");
        doc = (oracle.xml.parser.v2.XMLDocument) xml.getDOM(); // public org.w3c.dom.Document getDOM()
        System.out.println("convert2XMLDocument(): done casting w3c.Document naar oracle.XMLDocument.");
     catch (Exception e) {
        e.printStackTrace(System.out);
    return doc;
   private static XMLDocument convert2XMLDocument(XMLType xml) {
     // complex version: works ok !!!
     XMLDocument doc = null;
     try{
        DOMParser parser = new DOMParser();
        parser.setValidationMode(oracle.xml.parser.v2.XMLParser.NONVALIDATING);
        parser.setPreserveWhitespace (true);
        parser.parse(new StringReader(xml.getStringVal()));
        doc = parser.getDocument();
    catch ( XMLParseException e ) {
      e.printStackTrace(System.out);
    catch ( SQLException e ) {
      e.printStackTrace(System.out);
    catch ( Exception e ) {
      e.printStackTrace(System.out);
    return doc;
