Huge XML

[woodrain]

I am new to XML.
I will work on a huge XML file (42G, 12 million Records). But we only need a few elements. What tools or language I should use to capture only certain elements to a new file to make the file smaller.

You can use XSLT to capture certain elements and then if I remember correctly you can spit them out in another XML file..( I know that I had done something along these line using Xalan processor quite some time ago)

Is that 42 Gb? If I was your company I would split that into smaller files, and create a relation XML database web, because with a file size that large, the application costs to actually process the file will be HIGH and the processing time will also be HIGH.
