Re: [xsl] retrieve elements with same attribute values

[George Cristian Bina <george@xxxxxxxxxxxxx>]

Hi Charles,

Something like below would do it. That defines a key that matches all 
the items with the same author. Then iterates the authors and if there 
are more than 2 items matched then outputs them.

<?xml version='1.0'?>
<xsl:transform version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>

    <xsl:output method="text" indent="no"/>
    <xsl:key name="itemsByAuthor" match="item" use="author"/>

    <xsl:template match="/">
        <xsl:for-each select="//author[not(.=preceding::author)]">
            <xsl:if test="count(key('itemsByAuthor', .))>2">
                <xsl:for-each select="key('itemsByAuthor', .)">
                    <xsl:value-of select="../@name"/>
                    <xsl:text> : </xsl:text>
                    <xsl:value-of select="normalize-space(.)"/>
                    <xsl:text> : </xsl:text>
                    <xsl:value-of select="@name"/>
                    <xsl:text>&#10;</xsl:text>
                </xsl:for-each>
            </xsl:if>
        </xsl:for-each>
    </xsl:template>
</xsl:transform>

Regards,
George
