[jdom-interest] How to optimize xpath in jdom

[Michael Kay]

You might find that Saxon (which is able to read JDOM as an input document)
does a better job of this. In particular, Saxon-SA will build an index to
support this kind of expression.

Subject: [jdom-interest] How to optimize xpath in jdom



Hello, 

I am using Xpath available in jdom. The xml file is of 9MB size. It is
taking a lot of time to query a simple xpath like:

/Root/Parent/Child[name="abc"]/GrandChild 

I am trying to get the value of the "GrandChild" element in the following
way: 
((Element)org.jdom.xpath.XPath.selectSingleNode(xml_Document,
xpath_expression)).getValue(); 

There are many "Child" elements in my huge xml file of 9MB size. Please let
me know to optimize the xpath expression or any other workarounds.

Thanks in advance. 
Regards, 
Chandra
