Hi,

I want to do simple regular expression matching on an attribute value, which
is passed to a javascript extension function as a parameter, but I can't get
it working :-(

The javascript seems to recieve the XPath location of the attribute, rather
than it's value. E.g. "org.apache.xml.utils.NodeVector@ee7a14" instead of
"P1".

Relevant parts of the XSL:
---------------8<-------------------------

    <xalan:component prefix="regexp" functions="match">
        <xalan:script lang="javascript">
        <![CDATA[

// JS Regexp
function match(str, re, flags){
    var match = new RegExp(re, flags);
    return match.test(str) +  ", " + str + ", " + re;
}

]]>
        </xalan:script>
    </xalan:component>

    <xsl:template match="text:h|text:p">
        <xsl:copy>
            <xsl:attribute name="text:style-name">
                <xsl:call-template name="get-style-name">
                    <xsl:with-param name="STYLE_NAME"
select="@text:style-name"/>
                </xsl:call-template>
            </xsl:attribute>
            <xsl:apply-templates select="node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template name="get-style-name">
        <xsl:param name="STYLE_NAME"/>
        <xsl:value-of select="regexp:match($STYLE_NAME, 'P\d+')"/>
    </xsl:template>

---------------8<-------------------------



XML fragment:
---------------8<-------------------------
        <text:p text:style-name="P1">Morality</text:p>
---------------8<-------------------------



Output fragment:
---------------8<-------------------------
<text:p text:style-name="false, org.apache.xml.utils.NodeVector@ee7a14,
P\d+">Morality</text:p>
---------------8<-------------------------


Expected results:
---------------8<-------------------------
<text:p text:style-name="true, P1, P\d+">Morality</text:p>
---------------8<-------------------------

Any help would be most appreciated!

Cheers,
Dave.
