Instead of:
<xsl:variable name="bauteil_test">
<xsl:for-each select="/...//bauteil_id">
<xsl:if test="string(.) = string($wand_ID)">
<xsl:text>true</xsl:text>
</xsl:if>
</xsl:for-each>
</xsl:variable>
use:
<xsl:variable name="bauteil_test">
<xsl:if select="/...//bauteil_id[. = $wand_ID]">
<xsl:text>true</xsl:text>
</xsl:if>
</xsl:variable>
or better still:
<xsl:variable name="bauteil_test" select="boolean(/...//bauteil_id[. =
$wand_ID])"/>
(You can then convert the boolean to the string "true" using string() if you
want, but why not leave it as a boolean?)
