Hello All,

Can anyone explain me the meaning of the following line,

<xsl:when test="$pages[parent_id = $current_page/id]">

Thank you very much

Khwab Sheth

The test will succeed whenever the $pages variable contains a parent_id element that has its value equal to the value of the id element found in $current_page. Taking a guess based on the variable and element names it is checking whether the current page has a parent page.

Assuming that $pages holds a set of element nodes, and that $current_page holds a single element node, the expression tests whether one of the nodes in $pages has a child element called parent_id whose string value is equal to the string value of the id element that is a child of the node in $current_page.
