Thanks, I tried that already but i cannot get it right.

Here's a sample input (i left out the top level elements and started with the topmost div):

file1.xml:
<div type="edition_title" id="PLBAT">
<head><hi rend="b">Some text</hi></head>
<div type="papyrus_number" id="PLBAT1" n="1">
<head><hi rend="b">1</hi></head>
<div type="nr" id="PLBAT1_10" n="10">
<head><hi rend="b">10</hi></head>
<div type="zeile" id="PLBAT1_10_-" n="-">
<head>-</head>
<div type="entry" id="PLBAT1_10_-_BL5" n="10" part="-" vol="BL5" lang="ger" page="59">
<p>Some Text</p>
</div>
</div>
</div>
<div type="nr" id="PLBAT1_14" n="14">
<head><hi rend="b">14</hi></head>
<div type="zeile" id="PLBAT1_14_11-12" n="11-12">
<head>11-12</head>
<div type="entry" id="PLBAT1_14_11-12_BL5" n="14" part="11-12" vol="BL5" lang="ger" page="59">
<p>Sone text</p>
</div>
</div>
</div>
</div>
</div>


file2.xml:
<div type="edition_title" id="PLBAT">
<head><hi rend="b">Some text</hi></head>
<div type="papyrus_number" id="PLBAT1" n="1">
<head><hi rend="b">1</hi></head>
<div type="nr" id="PLBAT1_3" n="3">
<head><hi rend="b">3</hi></head>
<div type="zeile" id="PLBAT1_10_-" n="-">
<head>-</head>
<div type="entry" id="PLBAT1_10_-_BL5" n="10" part="-" vol="BL5" lang="ger" page="59">
<p>Some Text</p>
</div>
</div>
</div>
<div type="nr" id="PLBAT1_9" n="9">
<head><hi rend="b">9</hi></head>
<div type="zeile" id="PLBAT1_14_11-12" n="11-12">
<head>11-12</head>
<div type="entry" id="PLBAT1_14_11-12_BL5" n="14" part="11-12" vol="BL5" lang="ger" page="59">
<p>Sone text</p>
</div>
</div>
</div>
</div>
</div>


so using a xsl like this:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; xmlns:xs="http://www.w3.org/2001/XMLSchema"; exclude-result-prefixes="xs">
<xsl:template name="body">
<xsl:variable name="docs" as="node()*" select="collection(concat($path, '?select=*.xml'))"/>
<xsl:variable name="divs" as="node()*" select="$docs//TEI.2/text/body/div"/>
<xsl:for-each-group select="$divs" group-by="@id">
<div type="{current-grouping-key()}" id="{current-group()[1]/@id}">
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:for-each-group select="current-group()/node()" group-by="@id">
<div type="{current-group()[1]/@type}" id="{current-grouping-key()}" n="{current-group()[1]/@n}">
<!-- I want to insert a xsl:sort here so that i can sort the current-group() according to the @n -->
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:for-each-group select="current-group()/div" group-by="@n">
<div type="{current-group()[1]/@type}" id="{current-group()[1]/@id}" n="{current-grouping-key()}">
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:apply-templates select="div"/>
</div>
</xsl:for-each-group>
</div>
</xsl:for-each-group>
</div>
</xsl:for-each-group>
</xsl:template>


<!-- indentity template here -->
</xsl:stylesheet>

I should get:

<div type="edition_title" id="PLBAT">
<head><hi rend="b">Some text</hi></head>
<div type="papyrus_number" id="PLBAT1" n="1">
<head><hi rend="b">1</hi></head>
<div type="nr" id="PLBAT1_3" n="3">
<head><hi rend="b">3</hi></head>
<div type="zeile" id="PLBAT1_10_-" n="-">
<head>-</head>
<div type="entry" id="PLBAT1_10_-_BL5" n="10" part="-" vol="BL5" lang="ger" page="59">
<p>Some Text</p>
</div>
</div>
</div>
<div type="nr" id="PLBAT1_9" n="9">
<head><hi rend="b">9</hi></head>
<div type="zeile" id="PLBAT1_14_11-12" n="11-12">
<head>11-12</head>
<div type="entry" id="PLBAT1_14_11-12_BL5" n="14" part="11-12" vol="BL5" lang="ger" page="59">
<p>Sone text</p>
</div>
</div>
</div>
<div type="nr" id="PLBAT1_10" n="10">
<head><hi rend="b">10</hi></head>
<div type="zeile" id="PLBAT1_10_-" n="-">
<head>-</head>
<div type="entry" id="PLBAT1_10_-_BL5" n="10" part="-" vol="BL5" lang="ger" page="59">
<p>Some Text</p>
</div>
</div>
</div>
<div type="nr" id="PLBAT1_14" n="14">
<head><hi rend="b">14</hi></head>
<div type="zeile" id="PLBAT1_14_11-12" n="11-12">
<head>11-12</head>
<div type="entry" id="PLBAT1_14_11-12_BL5" n="14" part="11-12" vol="BL5" lang="ger" page="59">
<p>Sone text</p>
</div>
</div>
</div>
</div>
</div>

I believe TEI.2 is always the topmost element of a TEI doc? but // implies searching to arbitrary depth to find them all, your probably just want / there.

<!-- I want to insert a xsl:sort here so that i can sort the current-group() according to the @n -->
<xsl:apply-templates select="current-group()[1]/head"/>
<xsl:for-each-group select="current-group()/div" group-by="@n">


seems like you want to add <xsl:sort select="@n"/> at this point

hard to check without any input though-)
