newbie xslt help

[crash_override]

Hallo Forum,
I got a xml-based file to convert into a different form and to filter. No problem using xslt - but - because I'm pretty new to xslt I can't get it to work.
Example-xml:

Code: Select all

<?xml version='1.0' encoding='UTF-8'?>

<test>

	<point id="1" a="11" b="111">

		<tag k="name" v="a"/>

		<tag k="name2" v="a2"/>

	</point>

	<point id="2" a="22" b="222">

		<tag k="name" v="b"/>

		<tag k="adr" v="fun"/>

	</point>

	<point id="3" a="33" b="333"/>

	<point id="4" a="44" b="444"/>

	<point id="5" a="55" b="555"/>

	<point id="6" a="66" b="666"/>

	

	<line id="1" A="1111" B="11111">

		<pt ref="1"/>

		<pt ref="2"/>

		<pt ref="3"/>

		<tag k="rest" v="5"/>

		<tag k="abx" v="finish"/>

	</line>

	<line id="2" A="2222" B="22222">

		<nd ref="5"/>

		<tag k="hun" v="trips"/>

	</line>

	<line id="3" A="333" B="33333">

		<nd ref="2"/>

		<nd ref="5"/>

		<tag k="all" v="56"/>

	</line>

</test>

The resultant xml-file should include
1. all <line/> with 2 or more <pt/> (works with <xsl:if test="count(nd)>=2">) AND
2. all <point/> referenced by <pt ref="#"> including rule 1. => this is where my problems start.

The result should look like this (the original file to process is about 1GB!):

Code: Select all

<?xml version='1.0' encoding='UTF-8'?>

<test>

	<point id="1" a="11" b="111">

		<tag k="name" v="a"/>

		<tag k="name2" v="a2"/>

	</point>

	<point id="2" a="22" b="222">

		<tag k="name" v="b"/>

		<tag k="adr" v="fun"/>

	</point>

	<point id="3" a="33" b="333"/>

	<point id="5" a="55" b="555"/>

		

	<line id="1" A="1111" B="11111">

		<pt ref="1"/>

		<pt ref="2"/>

		<pt ref="3"/>

		<tag k="rest" v="5"/>

		<tag k="abx" v="finish"/>

	</line>

	<line id="3" A="333" B="33333">

		<nd ref="2"/>

		<nd ref="5"/>

		<tag k="all" v="56"/>

	</line>

</test>

=> <line id="2"> removed, too less <pt/>
=> <point id="4 and 6"> removed, not referenced (anymore)

Any hints?

Post your XSLT, and it'll be easier to see where you're going wrong.
