PL/SQL XML Parser (problem getting text of a node)

I am trying to get the contents of an ELEMENT (node with a CDATA section) using xmldom.getNodeValue(). However, it seems that there is a MAXIMUM number of characters that I can get back.
I think I've found a work-around using xmldom.writeToBuffer() which seems to write all of the CDATA contents to a VARCHAR2 variable. Now my problem is that it is using strings like '&#60' and '&#38'. I recognize these strings as being "internal representations of '<' and '&' respectively. I'd not have to replace every occurence of these types of strings with the ASCII equivalent -especially since I don't know all of the possible '&#nn' strings that may crop up.
Help!

The use of "//" or "\\" appears to be a bug in JServer. It has
been filed. You should not specify the path as a shared
directory as a workaround.

?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 -->
<person>
<employee>
<lastname>GHANTASALA</lastname>
<firstname>SREE</firstname>
<age>32</age>
</employee>
<employee>
<lastname>TAMATAM</lastname>
<firstname>SATISH</firstname>
<age>30</age>
</employee>
</person>
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 !

anybody seen this ??

There is no such limit on our Parser for PL/SQL. Could you
perhaps be using the PLXML Utilities? If you are you might try
our PL/SQL Parser instead.

Poweshell script to parse a XML document to get all Leaf level nodes with Node names in CSV

Hi Experts,
I want to write a Powershell script to parse a XML document to get all Leaf level nodes with Node names in CSV
<?xml version="1.0" encoding="UTF-8"?>
<CATALOG>
   <CD>
      <TITLE>Empire Burlesque</TITLE>
      <ARTIST>Bob Dylan</ARTIST>
      <COUNTRY>USA</COUNTRY>
      <COMPANY>Columbia</COMPANY>
      <PRICE>10.90</PRICE>
      <YEAR>1985</YEAR>
   </CD>
</CATALOG>
Need to display this as
CD_Tiltle, CD_ARTIST, CD_COUNTRY, CD_COMPANY, CD_PRICE, CD_YEAR
Empire Burlesque, Bob Dylan,USA,Columbia,10.90,1985
and so on..
I do not want to hard code the tag names in the script.
current example is 2 level hierarchy XML can be many level till 10 max I assume
in that case the csv file field name will be like P1_P2_P3_NodeName as so on..
Thanks in advance
Prajesh

Thankfully, I have writtenscript for ths same $node_name="";
$node_value="";
$reader = [system.Xml.XmlReader]::Create($xmlfile)
while ($reader.Read())
while ($reader.Read())
if ($reader.IsStartElement())
$node_name += "," + $reader.Name.ToString();
if ($reader.Read())
$node_value += "," + $reader.Value.Trim();

XML parsing problems with Oracle XML parser for PL/SQL

I am using the Oracle XML parser for PL/SQL to transform XML into HTML usign XSL. The parser gives me sporadic errors trying to parse various XML documents. For the same XML source, the XMLPARSER will parse without errors one day and the next day will give me errors such as "invalid char in text", "Expected ';'.", or even Java null pointer exceptions.
I have verified that the XML sources are well formed, so I am pretty certain that the problems I am having are bugs in the XMLPARSER.
Is there going to be a XML parser for PL/SQL version 2 that will fix these bugs? If so, when??? If not, is there anything else I could do to fix these problems?
Thanks!

You can use the latest version.

when the above xml file is read and populated into ITAB, for element vendorname-2 which has a space in first position , that space is ignored.
This is being used for a FB01 posting and vendor is paid based on Name1+Name2 printed on cheque and due to the space ignoring problem, the vendor name is displayed wrongly thus causing problems.
I appreciate if someone could guide me thru and help me in solving this problem.
How to preserve the leading or trailing space.
g_selementvalue = g_childnode->get_value( ).
when i check g_selementvalue, space is ignored.
i will be greateful if someone could guide me through.
Regards,
Simha

mean ? I think it means, that the Shuttle somehow sets itself to null ?! but i dont understand why...
There is no computation or anything that deletes the shuttle, the page is quite small, there is not much more than the shuttle and the validations and computations to give default value and transforming the shuttle items into a collection to continue working with the IDs.
I dont check whats the problem

XML Parser Problem

am using XML parser for PL/SQL in Oracle9i Enterprise Edition Release 9.0.1.1.1
When i run the sample xml program, i get error which is as follows. While compiling no errors. But while executing it reports error as given below.
SQL> execute domsample('c:\xml', 'family.xml', 'errors.txt');
begin domsample('c:\xml', 'family.xml', 'errors.txt'); end;

What need to be done to rectify the above problem.
when i do the following validation check

Please advice to how remove the following error:

Found the solution on metalink. There is a file under /$ORACLE_HOME/javavm/install/init_security.sql
which needs to be run under username where you are installing xml parser.
This step is not in readme.txt file provided as a part of download from the OTN website.

Create document with PL/SQL xml parser

Hello,
I'm trying to create a document with PL/SQL package xmldom on 8.1.7 and write to a file.
The problem is that my file is empty when it's created.
Can anyone send me an example of this simple problem or fullfill my example so it's works.
As you understand I'm new in using XML. :)
My example is:

Your problem may be memory for the JavaVM. Remember, the PL/SQL
parser uses the Java XML Parser APIs which run in a VM instance.
Are you running Oracle 8i? If you are you can access our Java
XML parser loaded in 8i's VM directly from your PL/SQL code.
That is in fact how our PL/SQL Parser does it.
Finally, we have no experience loading other XML Parsers into
Oracle.

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");

XML parser Problem in Oracle 9iAS

Dear All,
I am trying to parse a xml file by using a SAX Parser.
I am getting error "oracle.xml.parser.v2.XMLParseException: Invalid InputSource.'. I have already included 'xerces.jar' in the classpath.
But it is always taking oracle xml parser.

Adding Xerces XML parser is not enough to make it work. Since some version of JDK (I think 1.4.X) XML parser is included and for older version it can be setup like a runtime option. And this is probably how ORACLE is using its XML parser. If you want to use different parser, you have to pass runtime option to JVM - for Xalan it looks like this:
-Djavax.xml.transform.TransformerFactory=org.apache.xalan.processor.TransformerFactoryImpl
...this way it becomes default parser factory used by javax interface functions. Look for documentation on xml.apache.org

Faces-config.xml XML parser problem ???

I'm taking below error message when I was opening faces-config.xml file with diagram view, what's the exact solution of this problem???
Message
BME-99100: An error has been reported from the XML parser
Cause
The parse has reported the following error:
<Line 24, Column 2>: XML-20201: (Fatal Error) Expected name instead of <.
Action
Thanks for all...

I looked very well, there was'nt any error on line 24 about "<", I think if the size of faces-confic.xml file increased JDeveloper XML Parser cannot parse with high file size, what're other solutions?
