Re: [xsl] Adding an element to a list of similar elements?

["Jim Earley" <xml.jim@xxxxxxxxx>]

Dan,

You could try something like this:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"; version="1.0">
    <xsl:param name="to_add" select="''"/>
    <xsl:template match="node() | @*">
        <xsl:copy>
            <xsl:apply-templates select="node() | @*" />
        </xsl:copy>
    </xsl:template>
    <xsl:template match="/cruisecontrol/project.fullbuild">
        <xsl:copy>
            <xsl:copy-of select="node() | @*"/>
        </xsl:copy>
        <xsl:if test="not(following-sibling::project.fullbuild)">
            <project.fullbuild name="{$to_add}" buildAfterFailed="false"/>
        </xsl:if>
    </xsl:template>
</xsl:stylesheet>


Cheers,

Jim Earley
