I have the following problem. I have a couple of XML documents to merge

Each document has the same structure like this:

Is there any other and simpler way to - let's say - memorize the already
written blocks resp. identifiers?

Mike is correct that the variable-based grouping method would work with this, but it is far slower than an XSLT 2 approach. When using XSLT 1.0 I find variable-based grouping acceptable for sub-document and multi-document grouping.

The code would work along the lines of the following, and it assumes that there is an XML structure $files with the list of all the file names:

  <xsl:variable name="items"
                select="document($files/file/@uri,.)/root/block"/>
  <xsl:for-each select="$items">
     <!--walk through all, doing work at first of each unique idTag-->
     <xsl:if test="generate-id(.)=
                   generate-id($items[idTag=current()/idTag])">
        <!--the following executes once for each unique idTag
            value across all the files-->
     </xsl:if>
  </xsl:for-each>
