RE: [xsl] how to ask analyze-string for only one match?

[cknell@xxxxxxxxxx]

So, are you saying that with these elements:

  currentX=<xsl:value-of select="regex-group(2)"/>f;
  currentY=<xsl:value-of select="regex-group(5)"/>f;

you wish to extract the two numbers to the right of 'M'?

Subject:  [xsl] how to ask analyze-string for only one match?

I'm transforming svg.  In particular path data noted by the d attribute.
-----
 <path d="M 100 100 L 300 100 L 200 300 z"
       fill="red" stroke="blue" stroke-width="3" />
----
In this example there are 3 matches 100 100, 300 100 and 200 300.  The 
following gives me all 3 but I want it to stop after the first match.  
Added a {1} for group 1 but that doesn't stop the rematch from occuring.
-----
   <xsl:template name="apply-absolute-point">
   <xsl:param name="d-path" select="''"/>
           <xsl:analyze-string select="$d-path" 
regex="((\-?(\.|\d)+)(,| )+(\-?(\.|\d)+)){{1}}">
             <xsl:matching-substring>
         currentX=<xsl:value-of select="regex-group(2)"/>f;
         currentY=<xsl:value-of select="regex-group(5)"/>f;
             </xsl:matching-substring>
           </xsl:analyze-string>
   </xsl:template>
