Parser Docs

The URL http://technet.oracle.com/tech/xml/parser_java2/htdocs/relnotes.htm
contains the following sentence:
Important note: Documentation for Oracle XML Parser for Java is located in the doc directory in your install area.
I cannot find any XML documentation in either the doc or the install directories
for my 8.1.5 Oracle installation. Surely this documentation came with the product. What am I overlooking?
Thanks
Kristi Uthoff

This statement is referring to the installation of the parser that you download from this site. It was not included as part of the 8i install.

?xml version = '1.0' encoding = 'ASCII'? pl/sql xml parser

When ever I parse a document which has the
<?xml version = '1.0' encoding = 'ASCII'?> tag as the first line hangs the pl/sql xml parser . If I remove the "encoding = 'ASCII'" from the file everything works fine ! What is the problem ?
version 8.1.6 / plsql parser v2 / hpux 11x
Here is the input file
<?xml version = '1.0' encoding = 'ASCII'?>
!--- This is a comment -->

Here is my program
declare
p xmlparser.parser;
doc xmldom.DOMDocument;
dir varchar2(100) := '/apps/oracle/drugstore';
errfile varchar2(30) := 'err.txt' ;
inpfile varchar2(30) := 'person.xml';
nl xmldom.DOMNodeList;
len number;
n xmldom.DOMNode;
new_node xmldom.DOMNode;
node_name varchar2(100);
node_value varchar2(100);
begin
-- new parser
p := xmlparser.newParser;
-- Set some characteristics
xmlparser.setValidationMode(p, FALSE);
xmlparser.setErrorLog(p, dir| |'/'| | errfile );
xmlparser.setBaseDir(p, dir);
-- parse input file
xmlparser.parse(p, dir| |'/'| |inpfile);
-- get document
doc := xmlparser.getDocument(p);
-- get all elements
nl := xmldom.getElementsByTagName(doc, '*');
len := xmldom.getLength(nl);
dbms_output.put_line('Length='| |len);
-- loop through elements
for i in 0..len-1 loop
n := xmldom.item(nl, i);
node_name := xmldom.getNodeName(n);
-- get the text node associated with the element node
n := xmldom.getFirstChild(n);
if xmldom.getNodeType(n) = xmldom.TEXT_NODE then
node_value := xmldom.getNodeValue(n);
if node_name='lastname' then
dbms_output.put_line('The value you are looking for is -->:'| |node_value);
if node_value = 'GHANTASALA' then
xmldom.setNodeValue(n,'TEST2');
end if;
end if;
end if;
end loop;
new_node := xmldom.makeNode(doc);
xmldom.writeToFile(new_node, dir | |'/'| |'mod.xml');
end ;
null

The encoding header is actually generated by
by the following piece of code in my pl/sql program .
new_node := xmldom.makeNode(doc);
xmldom.writeToFile(new_node, dir | |'/'| |'mod.xml');
Since this is a document created by the pl/sql parser, I assume there is some meaning to it !
Also why is it hanging ? PL/sql parser should tell me that it is not a valid string !

JSTL - Problem parsing XML file w/ XML schema declarations

I'm having trouble parsing an xml document that contains XML schema declarations in the root element. I've included 2 snippets, the XML files they're supposed to parse, and their output below. The first one works and the second one doesn't. Could someone please tell me why? I find it hard to believe that no one's run into this before.
I'm running Tomcat 5.5 and I'm using JSP 2.0, jakarta standard taglibs jars (1.1.2), jdk 1.5.0_04, and the Xalan 2.7.0 jars.
Here's the first snippet:
<c:import url="/WEB-INF/config/schools.xml" var="xml" />
<x:parse doc="${xml}" var="schoolList"/>
There are <x:out select="count($schoolList//school)"/> schools in the file: 
<x:forEach select="$schoolList//school">
 <x:out select="name"/> 
</x:forEach>it parses the following xml file:
<?xml version="1.0" encoding="UTF-8"?>
<schools>
 <school id="34033">
 <name>Tumwater Middle School</name>
 <district>Tumwater</district>
 <type>middle</type>
 <active>false</active>
 </school>
 <school id="17001">
 <name>Garfield High School</name>
 <district>Seattle</district>
 <type>high</type>
 <active>true</active>
 </school>
 <school id="00023">
 <name>Tigard High School</name>
 <district>Tigard-Tualatin</district>
 <type>high</type>
 <active>true</active>
 </school>
</schools>and it outputs:
There are 3 schools in the file:
Tumwater Middle School
Garfield High School
Tigard High School-----------------------------------------
The second snippet:
<c:import url="/WEB-INF/config/schools2.xml" var="xml2" />
<x:parse doc="${xml2}" var="schoolList2"/>
There are <x:out select="count($schoolList2//school)"/> schools in the file: 
<x:forEach select="$schoolList2//school">
 <x:out select="name"/> 
</x:forEach>parses this xml file (note the xml schema declarations):
<?xml version="1.0" encoding="UTF-8"?>
<schools xmlns="http://www.serenus.com" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.serenus.com schools.xsd">

 <active>true</active>
 </school>
</schools>and its output is:
There are 0 schools in the file:That's it! No errors at all! I'm 100% certain the variable names, filenames, etc. are correct. I've looked everywhere for an existing answer to this problem, but I can't find one. Is this a known issue? Please help.

Hi Ben,
I got exactly the same problem and also could not find any solution.
Did you find a way out for this problem meanwhile?
Any help is welcome!

XML Parser for PL/SQL

Hi,
I have to produce and manipulate XML documents in PL/SQL. I have downloaded the XML Parser for PL/SQL from Oracle's web site.
Can anyone please:
1. Point me to some examples illustrating XML DOM manipulation with PL/SQL.
2. Any information about PL/SQL packages used for XML manipulation.
I am using Oracle 8i version 8.1.6
Thanks,
Rossen

I just ran the initjvm.sql,initdbj.sql and
initsqlj.sql.
Still getting the error.
Please help!!!!

Hi,
i found the problem :-)
I used the function apex_web_service.parse_xml to parse the SOAP response. The return datatype of this function is VARCHAR2. Therefore i get the error when the return value overflows.
Now i use the function apex_web_service.parse_xml_clob and it works fine.

How to parse an XML document with oracle8i

Has anyone a good link or an example how to decode and store an XML document into an oracle8i database.
I' ve found only good things for oracle9i.
Thank you
Roger

Here is an example of parsing xml taken fro Oracle8i 8.1.7 xdk.
This one uses external OS files to pase, but could be easily converted to
use CLOB or VARCHAR2 string for parsing XML documents.
IF you wanted to use CLOB to store and manipulate xml documents you can use XMLParser and XMLDom
packages along with the DBMS_LOB package to do that.
-- This file demonstates a simple use of the parser and DOM API.
-- The XML file that is given to the application is parsed and the
-- elements and attributes in the document are printed.

Error while parsing CLOB

I got following error while parsing clob :
ORA-20100: Error occurred while parsing: ORA-00942: table or view does not exist
ORA-06512: at "SYSTEM.XMLPARSER", line 22

Any Ideas ? What Table or View it is looking for ?

Need help on processing XML doc using Java store procedure

I am currently working on project to read, parse XML document and store data in XML document into database columns. I use JAVA API-OracleXMLSave in my java store procedure to do it, which use URL of XML doc to read, parse doc and store the data to database columns. My java store procedure works fine when XML doc is saved in server, but got "ORA-29532: Java call terminated by uncaught Java exception:
oracle.xml.sql.OracleXMLSQLException: No such file or directory" if XML doc is in client's PC instead of in server. I think the problem comes from the URL that created using OracleXMLSave
--createURL(fileName) based on the filename. what will be the filename if XML document located in Client PC like C:\myprojects\xmldoc.xml?
Thank you in advance if anyone can give some hints.

Adding external DOCTYPE causes "UnknownHostException" in x:parse

Hi,
I am using the following JSTL to parse and retrieve data from an xml file:
<c:import url="starfleet.xml" var="sf"/>
<x:parse doc="${sf}" varDom="dom"/>This works great but I am needing to add a DOCTYPE to the XML document:
<!DOCTYPE starship SYSTEM "starfleet.dtd" >As soon as that line is added I get the following error message on the JSP page:
org.apache.jasper.JasperException: javax.servlet.ServletException: javax.servlet.jsp.JspException: java.net.UnknownHostException: starfleet.dtdHowever placing the DOCTYPE internally brings up no problems e.g.
<!DOCTYPE starship [
]>
Any ideas why adding an external doctype is causing an "UnknownHostException"?
Thanks

Hi Dev,
When you create an external dimension, whether by creating it directly in an XML file or by transforming it from a source file, the dimension must conform to Endeca’s external_dimensions.dtd file before you import it into your project. The dtd file can be found here: $ENDECA_ROOT/conf/dtd. Also make sure to declare the dtd file in your XML:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE external_dimensions SYSTEM "external_dimensions.dtd">

SLOW XML DOM Parser

Hi All,
I am trying to a parse an XML File whose contents are given below:
<?xml version="1.0"?>
<inquiryresult sessionname="TheDataEnquiry" code="0" subcode="0">
<indexqueryresult code="0" subcode="0" queryname="AISClient range query">
<item objectname="Ncompass_SVS" mediastatus="m">
<rfield name="Amount" value="79427"/>
<rfield name="PostingDate" value="20030708"/>
<rfield name="Account" value="79427"/>
<rfield name="DRN" value="79427"/>
</item>
</indexqueryresult>
</inquiryresult>
In the above code i have to retrieve the "name" and "value" attributes of <rfield/> tag in each <item/>element.
The PL/SQL Procedure i used for data extraction is:
CREATE OR REPLACE PROCEDURE ParseXMLFile(xmlfile varchar2)
IS
p xmlparser.parser;
doc xmldom.DOMDocument;
nl2 xmldom.DOMNodeList;
nl3 xmldom.DOMNodeList;
n3 xmldom.DOMNode;
n4 xmldom.DOMNode;
e xmldom.DOMElement;
len2 number;
len3 number;
attrname varchar2(100);
attrval varchar2(100);
BEGIN
-- new parser
p := xmlparser.newParser;
-- parse input file
xmlparser.parse(p, xmlfile);
-- get document
doc := xmlparser.getDocument(p);
-- Free resources associated with the Parser as now it is no longer needed.
xmlparser.freeParser(p);
nl2 := xmldom.getElementsByTagName(doc, 'item');
len2 := xmldom.getLength(nl2);
-- loop through elements of item
FOR k IN 0..len2-1 LOOP
n3 := xmldom.item(nl2, k);
nl3 := xmldom.getElementsByTagName(xmldom.makeElement(n3), 'rfield');
len3 := xmldom.getLength(nl3);
-- loop through elements of rfield
FOR l IN 0..len3-1 LOOP
n4 := xmldom.item(nl3, l);
attrname := xslprocessor.valueOf(n4, '@name');
attrval := xslprocessor.valueOf(n4, '@value');
END LOOP;
END LOOP;
END;
But as soon I Parse an XML File greater than 10 MB, it takes a lot of time and gives me the java out of memory error.
Please advise me whether the above method I use to extract data from the XML file is efficient or not.
Thank You,

Hi,
When compared with SAX parsers, DOM parsers are a bit slow. They are best suited for small sized XML documents, but still going ahead with it, I have a suggestion that might improve the performance if the time taken for parsing the document into a DOM is very less when compared with the time taken for getting the values by looping thro' the DOM nodes.
Instead of finding the item nodes and then the rfield nodes you may directly check for them using the XPATH syntax like as follows
-- Getting a list of the RFIELD nodes in the document using the XPATH syntax.
v_nl := sys.xslprocessor.selectNodes(sys.xmldom.makeNode(v_doc),'/ITEM/RFIELD');
that should help you in avoiding lot many loops there by decreasing the time taken.

Pb with tag x:parse... JSTL

Hello,
I am begining in JSTL, I went to parse documents xml with the tags JSTL, but it doesn't work ...
I have a version of tomcat 5.0.25 and JDK 1.4.2
my Pb is as follows: that one I use the tags jstl for parser xml, according to the code below: essai.jsp
<%@ taglib uri="http://java.sun.com/jstl/core" prefix="c" %>
<%@ taglib uri="http://java.sun.com/jstl/xml" prefix="x" %>
<c:import url="essai.xml" var="xml" />
<HTML>
<BODY>
<x:parse doc="${xml}" var="test" scope="application" />
</BODY>
</HTML>
in the execution, I have the following error: "the attribute "doc". is incorrect for the tag parse according to the TLD indicated"
the same error when I change the attribute "doc" by "xml":
<x:parse xml="${xml}" var="test" scope="application" />
thank you for your help.

There is no attribute "doc" for <x:parse> in JSTL. The correct attribute name is "xml".
If you still get the error after you make the change, try restarting the servlet/JSP engine again. Perhaps it's hanging onto a cached version of the page.
