How to transform huge xml files in java?
- by fx42
As the title says it, I have a huge xml file (GBs)
<root>
<keep>
<stuff> ... </stuff>
<morestuff> ... </morestuff>
</keep>
<discard>
<stuff> ... </stuff>
<morestuff> ... </morestuff>
</discard>
</root>
and I'd like to transform it into a much smaller one which retains only a few of the elements.
My parser should do the following:
1. Parse through the file until a relevant element starts.
2. Copy the whole relevant element (with children) to the output file. go to 1.
step 1 is easy with SAX and impossible for DOM-parsers.
step 2 is annoying with SAX, but easy with the DOM-Parser or XSLT.
so what? - is there a neat way to combine SAX and DOM-Parser to do the task?
