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.

DOM XML parser program

Hi,
I am trying to write a sample program using DOM xml parser in java to read the values in a XML file.
please suggest me what are all the things I have to do for that.
I know Java and XML. I want to know how to access values from XML file in java.
Thanks

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.

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,

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...

Java.lang.ClassCastException: oracle.xml.parser.v2.XMLText cannot be cast to org.w3c.dom.Element

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.

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.

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.

How to ignore empty text element while using DOM to parse xml??

hi everyone,
i am using DOM to parse an xml file. But i dont know how to cinfig the DocumentBuilderFactory to ignore empty text elements.
For example, i have an xml file like this:
<?xml version="1.0" encoding="UTF-8" ?>
<root>
    <child>Tom</child>
    <child>Jerry</child>
</root>I used the following codes to parse:
String fname = "Tom-and-Jerry.xml";
DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance();
factory.setIgnoringElementContentWhitespace(true);
factory.setIgnoringComments(true);
DocumentBuilder builder = domFactory.newDocumentBuilder();
// Generate a DOM tree from the DOM builder.
org.w3c.dom.Document dom = builder.parse(new File(fname));
org.w3c.dom.NodeList list = dom.getChildNodes();
for (int i=0; i<list.getLength(); i++) {
    System.out.println("Child No."+i);
    System.out.println("NodeName="+list.item(i).getNodeName());
    System.out.println("NodeType="+getType(list.item(i).getNodeType()));
    System.out.println("NodeValue="+list.item(i).getNodeValue());
    System.out.println();
}The result is not exactly what i want ---- there are 5 children in list!! The 1st, 3rd and 5th are #text and their values are all empty. Only the 2nd and the 4th are the child that i expect.
It is really troublesome to get all these silly empty texts as sub elements. I tried to get rid of them, but i failed. I just dont understand why factory.setIgnoringElementContentWhitespace(true) did not work.
Anyone can help me? thanks.
Heavy ZHENG

I just dont understand why factory.setIgnoringElementContentWhitespace(true) did not work.That only does something if the XML has a DTD that enables it to know what whitespace can be ignored and what is significant. The API documentation for the method refers you to this document:
http://www.w3.org/TR/REC-xml#sec-white-space

Creating a dynamic jtree using datas retrieved by dom in xml parsing

help me with code to create a dynamic jtree using data retrieved as nodes by xml parsing using dom

Ok, so you want to make a tree. To determine the data that appears in a tree, you have to make a custom tree model. The API for this is at :
http://java.sun.com/j2se/1.4.2/docs/api/
A tutorial for using trees is at :
http://java.sun.com/docs/books/tutorial/uiswing/components/tree.html
I assume you are going to be using Nodes, since you are using XML. For this I might start with something like
class NodeTreeModel implements TreeModelI would then implement the 'getChildCount()' as the number of subnodes a node has, and the value of a tree node to the nodes value.
Hope that starts you off.

How can I use a 3rd party XML parser such as xerces with OC4J ?

Hi all tech experts,
I am using Oracle Application Server 10g Release 2 (10.1.2) and i have
installed Portal and Wireless and OracleAS Infrastructure on the same
computer.
i tried all the solutions on this thread
Use of Xerces Parser in out application with Oracle App Server 9.0.4
but still fighting.
I have also posted this query on OTN on following thread
How can I use a 3rd party XML parser such as xerces with OC4J?
but no reply....
Please help me on this issue.
Since OC4J is preconfigured to use the Oracle XML parser which is xmlparserv2.jar.
i have read the following article which states that
OC4J is preconfigured to use the Oracle XML parser. The Oracle XML parser is fully JAXP 1.1 compatible and will serve the needs of applications which require JAXP functionality. This approach does not require the download, installation, and configuration of additional XML parsers.
The Oracle XML parser (xmlparserv2.jar) is configured to load as a system level library of OC4J through it's inclusion as an entry in the Class-Path entry of the oc4j.jar Manifest.mf file. This results in the Oracle XML parser being used for all common deployment and packaging situations. You are not permitted to modify the Manifest.mf file of oc4j.jar.
It must be noted that configuring OC4J to run with any additional XML parser or JDBC library is not a supported configuration. We do know customers who have managed to successfully replace the system level XML parser and the Oracle JDBC drivers that ship with the product, but we do not support this type of configuration due to the possibility of unexpected system behavior and system errors that might occur from replacing the tested and certified libraries.
If you absolutely must use an additional XML parser such as xerces, then you have to start OC4J such that the xerces.jar file is loaded at a level above the OC4J system classpath. This can be accomplished using the -Xbootclasspath flag of the JRE.
i have also run the following command
java -Xbootclasspath/a:d:\xerces\xerces.jar -jar oc4j.jar
but no success.
How could i utilize my jar's like xerces.jar and xalan.jar for parsing instead of OC4J in-built parser ?
All reply will be highly appreciated.
Thnx in advance to all.

Hi Neeraj Sidhaye,
I am trying to deploy a sample xform application to the Oracle Application Server (10.1.3). However, I encountered the class loader issue that is similar to your stuation. I tried all the three solutions but the application is still use the Oracle xml paser class. I am wondering if you have any insight about this?
Thanks for your help.

XML parsing problem

Hi, my problem is :
In my Application i want to parse an XML file with DOM parser. The problem is that in my Project "MyProject -> Project Properties -> Libraries and Classpath"
I have included some 15 libraries which are useful for my Application: ADF Faces Runtime 11, ADF Web Runtime and etc.
Problems are causing the libraries: BC4J Runtime,ADF Model Runtime, MDS Runtime Dependencies
because when added my source which is parsing an XML file stops working.The source code is:
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
File file =
new File("C:\\Documents and Settings\\ilia\\Desktop\\begin.xml");
Document doc = db.parse(file);
Element root = doc.getDocumentElement();
NodeList dots = root.getElementsByTagName("w:t");
Element firstDot = (Element)dots.item(0);
String textValue = firstDot.getFirstChild().getNodeValue();
I use DOM because i need to change some values in the XML file, but its not working neither for reading nor for writing.When debugging I see that it gets the root of the xml but " firstDot.getFirstChild().getNodeValue() " returns null and it breaks with NullPointerException. And that's only when the libraries mentioned above are added to the project. Without them it works just fine !
I don't know, it's like when added the parser validates my xml against some schema and returns null.
The xml file is very simple MS Word Document saved as .xml .But I don't think that's the problem.
Thanks in advance !

Hi all,
I found the solution to my problem.The right way to parse and change an XML file with DOM parser using the Oracle XML Parser v2 should look like this:
JXDocumentBuilderFactory factory =
(JXDocumentBuilderFactory)JXDocumentBuilderFactory.newInstance();
JXDocumentBuilder documentBuilder =
(JXDocumentBuilder)factory.newDocumentBuilder();
File file = new File("c:/Documents and Settings/ilia/Desktop/begin.xml");
InputStream input =
new FileInputStream(file);
XMLDocument xmlDocument = (XMLDocument)(documentBuilder.parse(input));
System.out.println("Encoding: " + xmlDocument.getEncoding());
System.out.println("Version: " + xmlDocument.getVersion());
NodeList namespaceNodeList =
xmlDocument.getElementsByTagNameNS("http://schemas.microsoft.com/office/word/2003/wordml","t");
XMLElement namespaceElement17 = (XMLElement)namespaceNodeList.item(17);
namespaceElement17.getFirstChild().setNodeValue("someString");

Loading XML parser for PL/SQL

I am working my way thru 'Building Oracle XML Applications' by Steve Muench.
I am getting a problem when I try to install the XML parser for PL/SQL
The following errors occur when I try to do
loadjava -v -r -u xmlbook/xmlbook xmlparserv2.jar
initialization complete

About 20 classes get loaded correctly. All the rest get ORA-29545 or ORA-04043 errors.
I expect the ORA-04043 errors are a result of the earlier errors.
The documentation seems to indicate that there is no need to do
dbms_java.grant_permission to load into your own schema.
I have NT4 (sp6)
Oracle 8.1.7
xmlparserv2.jar dated 24/8/2001 17:01 size 1,177,259
xmlparserv2_2027.jar gives the same errors.
Any help would be appreciated.
null

Was it definitely xmlparsev2.jar that you had to load?
I recently started going through some of these examples as well and found that the standard xml parser was there but that I needed to load the xml parser for PL/SQL. I did this using loadjava from a subdirectory within the xdk directory and everything worked fine.

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.
