Thanks David. I think you are right. This may simplify my need to group and
sort.

Subject: Re: [xsl] Function to Extract integer from string
BTW, what does
"'regex="\d+\.?\d*"' do?
\d is a digit so \d+ is one or more digits \. is a . so \.? is 0-or-1 .
and \d* is zero or more digits
[0-9] also matches digits but with a rather anglo-saxon.ascii view of
what constitutes a digit. \d matches any unicode character with the
appropriate digit property. Still I doubt that US code of Federal
Regulations uses digits from non latin scripts so it probably comes to
the same thing in this case
<xsl:variable name="all" select="replace(.,'[^
0-9\.]','')"/>
<xsl:variable name="numbers" as="xs:string*">
<xsl:analyze-string select="$all" regex="\d+\.?\d*">
<xsl:matching-substring>
<xsl:sequence select="."/>
</xsl:matching-substring>
</xsl:analyze-string>
</xsl:variable>
I think that's just giving the sequence of numbers which you could do as
<xsl:variable name="numbers" as="xs:string*"
select="tokenize(.,'[^0-9\.]+')"/>
David
