Question

I have an XML file with the following structure:

<root>
    <level1>
        <level2>
            <value>A</value>
            <value>B</value>
            <value>C</value>
            <value>D</value>
            <value>E</value>
            <value>F</value>
        </level2>
    </level1>
</root>

Guess I want to concatenate only the first three values in XSL in order to get ABC. How do I do it?

Answer 1

Assuming the focus item is the level2 node, you can use a XSLT 1.0 sequence constructor like…

<xsl:value-of select="concat(value[1],value[2],value[3])" />

…or in XSLT 2.0…

<xsl:value-of select="for $i in 1 to 3 return value[$i]" />
