OK, I got it. Here's the new version of the template for the thousands of
readers who have been holding your collective breath.
<xsl:template name="extract-minutes-as-seconds">
<xsl:param name="time" />
<xsl:analyze-string select="$time" regex="([0-9]+) minute(s)?.*$">
<xsl:matching-substring>
<xsl:value-of select="60 * xs:integer(regex-group(1))"
/>
</xsl:matching-substring>
<xsl:non-matching-substring>0</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>

Subject: Re: [xsl] xsl:analyze-string explanation needed
are you saying that I should change the regex so that it matches the
entire input string rather than the part I'm interested in,
yes
then there will only be one substring aafter the regex analysis, either
1 matching substring (the whole string) or one none matching substring.
