Question

Newbie question on xslt. I’ve multiple xsl:if checks like

<xsl:if test="node/node1"> ...</xsl:if>
...
<xsl:if test="node/node1"> ...</xsl:if>
...
<xsl:if test="node/node1"> ... </xsl:if>

Is there a way to parameterize the test condition to make the code more readable and easy to maintain? Maybe with a variable or something like

<xsl:variable name="node1Present" select="true()"/>
<xsl:if test="$node1Present"> ... </xsl:if>

I don’t understand how to construct the variable to reflect the ‘test a node exist’ (test=”node/node1″)

Answer 1

<xsl:variable name="node1Present" select="boolean(node/node1)"/>

For node-sets, boolean() converts to true, if and only if the node-set is not empty.
