if para2 is an empty element, then the regex success and

empty is a non-matching regex ?
Further to Joe's response: analyze-string partitions the input string into a
sequence of substrings, passing substrings that match the regex to
xsl:matching-substring and those that don't match to
xsl:non-matching-substring. If the input is empty, there will be no
substrings, therefore no calls on either xsl:matching-substring or
xsl:non-matching-substring.
If you want to test whether the string as a whole matches the regex, use the
matches() function.
Ok I think I am getting closer now. My goal is simply to recursively
iterate over preceeding <para> element in search for a matching regex.
I must have made a mistake with the recusion calls...
<article>
<para>C.1. section</para>
<para>C.1.1 section</para>
<para>bla</para>
<para>C.1.1.1 section</para> <!-- correct solution -->
<para>foo</para>
<para/>
<para>bar</para>
<table>mytable</table>
</article>
