I have an xhtml-file (nothing special at it). Now I would like to number the h?-tags (like h1=1 h2=1.1 h3=1.1.1).

My xslt-code is like this:

<xsl:template match="/">
   <xsl:number level="multiple" lang="de" grouping-separator="." count="h1|h2|h3" format="1.1.1" />
</xsl:template>


But if I apply this to my xhtml-file I get the following fault:

Unimplemented block at preproc.c:725
Segmentation fault


any idea where the bug is? thanks!

The problem is clearly something to do with your XSLT processor or your processing environment, which you have told us nothing about. You need to go to your vendor's product support site.

Well, I use xsltproc. The command looks like:

$ xsltproc number.xsl website.xhtml > /tmp/output.xhtml

[number.xsl includes the posted xslt-code]
[website.xhtml is a simple xhtml-file]

by the way: is the xsl:number-code correct?

I thought the format is can be one of the following:
format="1" results in 1 2 3 . .
format="01" results in 01 02 03
format="a" results in a b c . .
format="A" results in A B C. .
format="i" results in i ii iii iv . .
format="I" results in I II III IV . .

Try without any attributes and see processor runs it, if it does try adding one attribute and check where is the problem!

lang="de" was the problem. looks like xsltproc don't like it ;)! without there is no problem! thanks!
