Thanks for the explanation.

I think that, I'm finally able to write an XSLT solution, the way you
suggested earlier (i.e, using string-length(translate( ... to compute the
count). Below is my attempt, that seems to work fine,

<xsl:stylesheet version="3.0" xmlns:xsl="
http://www.w3.org/1999/XSL/Transform"
                                               xmlns:xs="
http://www.w3.org/2001/XMLSchema"
                                               exclude-result-prefixes="xs">

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

   <xsl:template match="/">
      <xsl:variable name="temp_result">
          <xsl:analyze-string
select="'abhello1cdehello2fghijklhello3hello4mhello5nhello6'"
                                         regex="hello[1-9]">
             <xsl:matching-substring>
                <xsl:value-of select="1"/>
             </xsl:matching-substring>
             <xsl:non-matching-substring>
        <xsl:value-of select="0"/>
             </xsl:non-matching-substring>
          </xsl:analyze-string>
      </xsl:variable>
      <result>
<yes count="{string-length(translate($temp_result, '0', ''))}"/>
<no count="{string-length(translate($temp_result, '1', ''))}"/>
      </result>
   </xsl:template>

</xsl:stylesheet>

With above mentioned XSLT stylesheet, the thing that worked is, not
explicitly declaring the type for xsl:variable name="temp_result".
