xpath evaluation on xml document's sax input

[Mukul Gandhi <mukulg@softwarebytes.org>]

Hi all,

   I was researching a bit, on this topic, and came across the following thread on stackoverflow,

https://stackoverflow.com/questions/26996504/in-java-how-do-i-evaluate-xpath-expression-on-xml-using-sax-parser

i.e, can we have a general purpose xpath expression evaluator, on xml document's sax stream input?

My assessment is that, a general purpose xpath expression evaluator, would always require some form of tree representation (of an xpath data model) of an entire xml input document.

Any thoughts would be interesting to know.
