Please try the following stylesheet:

<?xml version="1.0" encoding="UTF-8" ?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                       xmlns:exslt="http://exslt.org/common"
                       exclude-result-prefixes="exslt"
                       version="1.0">

  <xsl:output method="xml" indent="yes" />

  <xsl:variable name="doc" select="/" />

  <xsl:template match="/files">
    <data>
      <xsl:for-each select="document(file[1]/@href)/data/line">
        <line>
          <xsl:copy-of select="@ref" />
          <xsl:variable name="ref" select="@ref" />
          <xsl:attribute name="amount">
            <xsl:variable name="sumOfAmounts">
              <xsl:for-each select="$doc/files/file">
                <num><xsl:value-of
select="document(@href)/data/line[@ref = $ref]/@amount" /></num>
              </xsl:for-each>
            </xsl:variable>
            <xsl:value-of select="sum(exslt:node-set($sumOfAmounts)/num)" />
          </xsl:attribute>
        </line>
      </xsl:for-each>
    </data>
  </xsl:template>

</xsl:stylesheet>

These files should be merged into a variable, which can then be further processed; in my example below the @amount of each line[@ref] is summed. But I'm already stuck in the first part of this, how do I correctly put file1.xml and file2.xml into a variable which then contains (psuedo) "<root><data><lines/></data>><data><lines/></data></root>"? And how can I then use that variable as a basis for further processing?
