Skipping xml entries with xsl

[Andreas W. Wylach]

Hello everybody,

i got a problem in building a xsl construct to skip xml entries. Xml
looks like this:

....
<textblock>
<text_crlf></text_crlf>
<text_crlf></text_crlf>
<text_crlf></text_crlf>
<text_crlf></text_crlf>
<text_crlf></text_crlf>
<text_crlf></text_crlf>
</textblock>
....

Above xml code is a little part out of a whole xml tree. The problem
i try to solve is to print out the first text_crlf tag (which will be
translated in <br> via a match function. All the following text_crlf
entries should be skipped, _if_ they are empty.
I tried to work with following/preceding-sibling and such but can't get it
to work.
I am not very xml expirienced, so maybe one of you wizards can give me a hint
how to get that problem solved.

Greetings

<xsl:template match="text_crlf[1]">
<br>
</xsl:template>

<xsl:template match="text_crlf[position() != 1 and . = '']"/>

<xsl:template match="text_crlf[position() != 1 and . != '']">
<!-- do some stuff here -->
</xsl:template>
