I have an XML file of the following format
<PROGRAM>
<FUNCTION>
<NAME>.insertR_3</NAME>
<BASICBLOCK>
<NAME>entry</NAME>
<INSTCOUNT>7</INSTCOUNT>
<INST>
<OPCODE>getelementptr</OPC
<TYPE>sbyte *</TYPE>
</INST>
<INST>
<OPCODE>load</OPCODE>
<TYPE>sbyte</TYPE>
</INST>
<INST>
<OPCODE>cast</OPCODE>
<TYPE>int</TYPE>
</INST>
<INST>
<OPCODE>setlt</OPCODE>
<TYPE>bool</TYPE>
....
and so on ,..
I want to extract all the INST elements where say TYPE is "int" ,
I want the OPCODE for such INST and also the BASICBLOCK name and also the FUNCTION to which it belongs too ..
I am very much new to all these XML.
Thanks ,
Abhijit

Oops! Submitted before finished editing the code part. Here's the correct one:
var instNode = xml.selectSingleNode("//IN
var opcode = instNode.selectSingleNode(
var basicBlock = instNode.parentNode.select
var functionName = instNodes.parentNode.paren
If you have multiple INST with type int
var instNodes = xml.selectNodes("//INST[./
please note, DOM is quite good, but memory consumption is big.
If, only you need to read data once, and store somewhere, it's better to use XmlReader (or XPP, is you are using JAva) or SAX approach. Probably if, only you need is some data manipulation you can use XSLT and sava yourself much development time.
Thank you sathish and dualsoul,
as such I am quite new with XML , so am not much awatre of DOM ( or even xmlreader )
So I was wondering if using libxml2 (http://xmlsoft.org/ ) give me the solution ? will it be simpler ?
libxml2 is good one. It supports all three models: SAX/XPP/DOM :) you can choose any you like, which is most suitable for your task. By the way you can say us what the task is, and possibly we can recommend you the easiest way to acheive it.
Check this link: http://alphaworks.ibm.com/
there are a lot of tutorials on XML processing, you can read some on SAX or DOM to get better understanding of concepts.

I assume you are using DOM. Following is a brief example:
var xml = new ActiveXObject("Microsoft.X
xml.async = false
xml.loadXML("test.xml")
To select the INST with type 'int'
var instNode = xml.selectSingleNode("//IN
// if you have multiple INST elements with type int you can usevar instNodes = xml.selectnodes("//INST[./
To get the OPCODE, BASICBLOCK and FUNCTION values
var opcode = instNodes.item(0).childNod
var basicBlock = instNodes.item(0).parentNo
var functionName = instNodes.item(0).parentNo
Hope this helps.
Cheers,
Sathish
