Hi guys,

Thanks a lot for all your answers. It looks like XSLT can be used for
everything :)

What Michael wrote was exactly what I needed. I just tweaked a bit the
output, to make it (the output) more human-readable:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="";
	<xsl:output method="text"/>
	<xsl:template match="file">
		<xsl:text>INCONSISTENCIES FOUND&#xA;</xsl:text>
		<xsl:for-each-group select="unit" group-by="source">
			<xsl:if test="count(distinct-values(current-group()/target)) gt 1">
				<xsl:text>Segment [</xsl:text>
				<xsl:value-of select="current-grouping-key()"/>
				<xsl:text>]&#xA;translated as:&#xA;[</xsl:text>
				<xsl:value-of select="distinct-values(current-group()/target)"
separator="] and &#xA;["/>

So I get


Segment [bleble]
translated as:
[pleple] and

That function conflicts-for must be quite new, it's not in my O'Reilly book.

Once again: really, thanks a lot.

Cheers, Manuel
