Select nodes by filter

[Norbert Pürringer]

Hello!

I've got following XML structure

<ROOT>
<DATASET>
<ID>1</ID>
<VALUE>Test1</VALUE>
</DATASET>
<DATASET>
<ID>2</ID>
<VALUE>Test2</VALUE>
</DATASET>
<DATASET>
<ID>3</ID>
<VALUE>Test3</VALUE>
</DATASET>
</ROOT>

I want to select all dataset nodes having a certain id value.

SelectNodes will give me a collection of ALL dataset nodes.

I need something like SelectNodesByFilter("ROOT/DATASET", "ID < 3")

Does someone know a way how to solve that problem optimally?

Regards,
Norbert

SelectNodes("/ROOT/DATASET[number(ID) gt 1]") will return the set of nodes
whose ID value is greater than 1.

xmlDocument.SelectNodes("ROOT/DATASET[ID < 3]")
