Hi I am trying to extract units and measure from a string with the example provided here:

http://www.dpawson.co.uk/xsl/rev2/re...tml#d17781e331

My result is only non-matching-substring output - what am I doing wrong?

Code:

<xsl:template match="unitofmeasure">
        <xsl:analyze-string select="." regex="^(\d*(\.\d*)(in|cm|lbs|m))">
            <xsl:matching-substring>
                <measure>
                    <xsl:value-of select="regex-group(1)"/>
                </measure>
                <units>
                    <xsl:value-of select="regex-group(3)"/>
                </units>
            </xsl:matching-substring>
            <xsl:non-matching-substring>
                <value>
                    <xsl:value-of select="."/>
                </value>
            </xsl:non-matching-substring>
        </xsl:analyze-string>
    </xsl:template>

Input:

Code:

<root>
    <unitofmeasure type="lbs.2.kg">15.6lbs</unitofmeasure>
    <unitofmeasure type="inch.2.cm">14in</unitofmeasure>
    <unitofmeasure type="feet.2.m">14ft</unitofmeasure>
</root>

Current output:

Code:

<value>15.6lbs</value>
<value>14in</value>
<value >14ft</value>

Your first example matches the regex, but regex-group(1) is the whole string: position the parentheses differently if you just want the number.

Your second and third examples don't match because the regex makes the decimal point mandatory, and the third one also doesn't match because "ft" is not in your list of units of measure accepted by the regex.
