Use of XML parser to read/parse xml stored in DB as CLOB

Hello,
I am new to XML technology. I have xml data stored in DB as
CLOB. I need to parse this data to retrieve VALUE fro certain
tags. I would greatly appreciate any help. Any examples that
manipulate xml data stored in DB can be of extreme help.
DesiDBA

As you use Oracle 9.0.1. We suggest you use XMLType instead of
CLOB to store your XML documents.
You can use xmlType.extract() to get the elements within the
XMLDocuments.
Please refer to our Oracle9i XML Demo for examples.
http://otn.oracle.com/tech/xml/xdk_sample/xdkdemo_faq.html
For Instructions:
http://ws5.olab.oracle.com/faqdemo/source/instruction.xsql?
pagename=ins_xmltype
Or you have to do the SQL query to get XML documents and parse
each document and extract the content yourself using XML Parser
for PL/SQL.
Thanks.

I am trying to read this data using the xpath.. and its going crazy with out reading the xml.
When I use the dom object to read this xml its failing to read the xml file.
When i tried to remove the header part and read the xml file its working fine.
I appreciate if some one can have the inputs in this.
Thanks

You aren't allowed to use element names which begin with "xml".

but the problem is i want to read (parse) any XML file means any Elemets would be change any time using SAX .In the above example
else if (elemName.equals("Heat")) {
else if (elemName.equals("IndexREDId")){
} else if (elemName.equals("Maturity")) {
like above I am doing hard code Elements names and reading the values so i don't want hard coding the elements names I want to read any element name and value dynamically.
If i give any one below XML file i want to read the Elements and displaying to console without changing any code i want to read the XML document.
EX:
Student.XML: <root>..</StName>..</StAge>...</root>
Employee.XML: <root>..</EmpName>..</EmpAge>...</root>
CdCatalog.XML: <root>..</Cdtitle>...</CdNumber>...</root>
I need one java program can ready any type of XML file elements and send to the Database table.
Please any one done like this task please suggest some reference links or books or sample snippet which can help me to develop program in my requirement.
Thanks in advance

How to read xml-stylesheet Processing Instruction from XML using DOM Parser

Hi,
I am trying to read an xml that contains xsl stylesheet PI using DOMParser. The parse() method reads the entire contents of the XML except the PI instruction. Below is the XML I am using to read
<?xml version="1.0" encoding="ISO-8859-1"?>
<?xml-stylesheet href="../../../lang/en-us/style0/usc_profile.xsl" type="text/xsl"?>
<Oblix oblang="en-us" xmlns="http://www.oblix.com/" xmlns:oblix="http://www.oblix.com/">
<ObProfile>
</ObProfile>
</Oblix>
Can anyone let me know if there are any propery settings to be done for the DOM parser before parsing?. If so, what is the property to be set?.
Thanks in Advance
Muthu

A COTS product builds the XML and inserts the respective xsl (xml:stylesheet) file name to be used for transforming the xml. I am trying to interrupt this xml and make some updations on an element and finally send the updated xml to the stream.
For the above process, I parse the input XML using DOMParser and update the elements (some internal elements). While I view the final XML that would be passed to the stream, I found the <?xml-stylesheet... PI is missing.
I somehow managed using a temp fix by doing the below. I manually pulled the PI using document.getFirstChild().getNodeValue() and reconstructed the PI and inserted it to the outgoing XML. This needs to be done every time. This might run into problems when more than one PI is used in the XML.
If the parsed XML could get the PI along with it the above problem could be resolved.
Is there any property that could be set on the parser (prior to parsing) to resolve the issue?.

How to parse xml file to read the tags

Hi All,
I am having a requirement to read the tags from the xml file(xml parsing).
The main issue is *xml file is stored in the table with xml type column* (not placed directly in the server) and we have to read the tags from that xml file.
Please help me to achieve it.
Regards,
Akshata

Hi,

The main issue is xml file is stored in the table clob/blob type column (not placed directly in the server) and we have to read the tags from that xml file.How is that an issue? On the contrary, it's better when the data already resides in the database, though it should be in an XMLType column to leverage the full capacity of the Oracle parser.
What's the datatype of the column exactly? CLOB or BLOB?
Either way you'll have to convert in to XMLType datatype using the XMLType constructor.
Did you go through the countless examples on this forum? Examples with XMLTable should be helpful.
Post some sample data and database version if you need additional guidance.
Thanks.

Hi Laks
Here is an example of converting a XML doc to a DOM object.
The method is ParseXML(pXMLString:TextData, pListType:CSAListInterface).

Need to Parse or Read XML into a ResultSet

Hi, I see lots of examples of folks reading from a database, populating a ResultSet, and then putting that data into an XML document. I don't see any reference to going the other way, and was hoping some of you might have an insight on how to do this.
We have a huge historical database and want to take the older info, put it into xml format, zip it, and store the zip'd result as a blob. That's the easy part.
We want to be able to go back, to read the blob, unzip it, and then populate a ResultSet and return that to the caller. I don't see any slick methodology to either 1.) instantiate an empty ResultSet or 2.) parse/read an XML structure into a ResultSet.
Any bright ideas?
Thanks, John

@maggie: That is easily done with XPath expressions, for example:
xmlstarlet sel -t -m '//servers[@country_code="us"]' -c '.' -n vpn.xml
xmlstarlet sel -T -t -m '//servers[@country_code="us"]' -v @public_name -o " " -v @bw -n vpn.xml
xmlstarlet sel -t -m '//servers[@country_code="us"]' -v '@public_name' -o ": " -v '@currentload' -n vpn.xml
xmlstarlet sel -t -m '//servers[@country_code="us" and @currentload<15]' -v '@public_name' -o ": " -v '@currentload' -n vpn.xml

jshon -e servers -a -e country_code -u -p -e public_name -u -p -e bw -u <vpn.json | {
# filter country_code
while read -r country_code && read -r public_name && read -r bw; do
[ x"$country_code" = x"ca" ] && echo "$public_name $bw";
done
} | sort -k2,2nr -k1,1d # sort second field (bw) numeric reverse, if equal use dictionary sort on first (name)

HO w to use SAX parser to create an XML file on the fly

Hi All,
Currently I am using the DOM parser to create an XML file from a text file. But as the DOM takes much memory and inefficient, I need to convert the DOM translator to SAX translator. Can I do that ?? If YES then how to go about that and if NO then what may be the workaround for that.
Please help me out
Thanx in advance
kaushik

Incidentally, look at this thread:
http://forum.java.sun.com/thread.jsp?forum=34&thread=252415
It has an example of how to transform an XML file via XSLT. If you change this to use the zero-argument form of newTransformer, it will apply the "identity transformation" to your input, thus outputting your XML in valid form. Now you just need to figure out how to provide SAX input to this, and the JAXP download includes an example of that.

How to validate XML against XSD and parse/save in one step using SAXParser?

How to validate XML against XSD and parse/save in one step using SAXParser?
I currently have an XML file and XSD. The XML file specifies the location of the XSD. In Java code I create a SAXParser with parameters indicating that it needs to validate the XML. However, SAXParser.parse does not validate the XML, but it does call my handler functions which save the elements/attributes in memory as it is read. On the other hand, XMLReader.parse does validate the XML against the XSD, but does not save the document in memory.
My code can call XMLReader.parse to validate the XML followed by SAXParser.parse to save the XML document in memory. But this sound inefficient. Besides, while a valid document is being parsed by XMLReader, it can be changed to be invalid and saved, and XMLReader.parse would be looking at the original file and would think that the file is OK, and then SAXParser.parse would parse the document without errors.

Have you looked at the XML DB FAQ thread (second post) in this forum? It has some examples for validating XML against schemas.

Parse an Aggregate in XML Document using PL/SQL

Hi. I've been successful with parsing a TAG in XML Document stored in CLOB using PL/SQL XML Parser.
However, I need help on how to get the whole aggregate in XML Document stored in CLOB.
sample XML Doc :
<library>
<book>
<title>Oracle Complete Reference</title>
<author>Kevin</Author>
<year>2000</year>
</book>
<video>
<title>Learning C++</title>
<length>2 hours</length>
<video>
</library>
I need a function that will accept an Input which is the aggregate name and will return the aggregate value.
With the sample XML above, say the input is 'VIDEO', the function will return :
<video>
<title>Learning C++</title>
<length>2 hours</length>
<video>
I'll really appreciate any help.

I used such an example to parse several Varchar2 strings in a given DB session:
BEGIN
parser := xmlparser.newparser ;
xmlparser.parsebuffer(parser,xmlout) ;
domdoc := xmlparser.getDocument(parser) ;
xmlparser.FREEPARSER(parser) ;
parser.id := -1 ;
nodes := xslprocessor.selectNodes(
xmldom.makenode(domdoc),
'Positionen/Position') ;
for i in 1 .. xmldom.getLength(nodes) loop
node := xmldom.item(nodes,i-1) ;
-- do s/thing with the node
end loop ;
xmldom.freedocument(domdoc) ;
RETURN(komponenten) ;
EXCEPTION
WHEN OTHERS THEN
if parser.id <> -1 then xmlparser.freeparser(parser) ;
end if ;
if domdoc.id <> -1 then xmldom.freedocument(domdoc) ;
end if ;
RAISE ;
END ;
However, after about 2000 of nodes lists parsed, I get an ArrayIndexOutOfBoundsException from XMLNodeCover. Obviously, I should release the nodes or the nodelist, but I have not found any procedure to do this.

XML Parser - Reading an XML document into the DocumentObject

Hi guys,
I have been trying to read an XML file and feed it into the XMLParser.
I have read about the DOM API, and i can work with the DOM API in java
scripts. How
will i play with it in TOOL implementation of DOM API. Can anyone guide me
in this
process.
Thanks for your help.

Sorry for this post, here ist the complete text.
Is it possible to create a XML Parser (javax.xml.parsers.SaxParser or javax.xml.parsers.DocumentBuilder) which reads from a ByteChannel?
Example:
java.nio.channels.FileChannel fc = new ...;
javax.xml.parsers.SaxParser parser = ...;
org.xml.sax.HandlerBase hb = ...;
parser.parse( fc, hb );

I want to create a parser file which dynamically reads out XML file.

HI ,.
I created a DOM parser where i am getting the values of XML file by tag names...
which is increasing my code lines number ...
So can any one suggest me with proper way of approach to overcome this....

Reading an xml file in actionscript using flex3

plzz tell me how to read an xml file in actionscript using flex3.......

One possible option to parse an xml-file to a flex XML object:
public function parseConXML(source:String):void
                xmlLoader = new URLLoader();
                xmlLoader.load(new URLRequest(source));
                  // Eventlistener: if URL loaded --> onLoadComplete function
                  xmlLoader.addEventListener(Event.COMPLETE, xmlLoadComplete);
            public function xmlLoadComplete(evt:Event):void{
                var xml:XML = new XML();
                 // ignore comments in XML-File
                XML.ignoreComments = true;
                   //ignore whitespaces in XML-File
                 XML.ignoreWhitespace = true;
                // XML-Objekt erstellen
                xml = new XML(evt.target.data);
               //AFTERWARDS use your xml as your wish
