RE: Constructing hierarchical XML from a flat XML-tag

This is a kind of grouping problem which I call "positional grouping".

In XSLT 2.0 you can do

<xsl:for-each-group select="*" group-starting-with="a">
  <a>
   <xsl:copy-of select="current-group() except ."/>
  </a>
</xsl:for-each-group>

In 1.0 my usual approach is

<xsl:for-each select="a">
  <a>
    <xsl:copy-of select="following-sibling::*
         [generate-id(preceding-sibling::a[1])=generate-id(current())]">
  </a>
</xsl:for-each>
