Description
-
If node is similar to the <xsl:if> instruction. It intends to
provide a way to execute conditionnal instructions. Like <xsl:if>
instruction, there is no else [if] corresponding statement. You must
use the negation of the condition in another if node in order to
get an else equivalent.

<if test=".[@language='java']">

</if>
<if test=".[@language='ada']">
...
</if>
<if test=".[@language!='java' and @language!='ada']">
...
</if>

This sample shows conditionnal if blocks: the first one tests if
current node has a language attribute set to "java";
if this is true, child nodes of this if node will be executed; the
second one is very similar, and the last one is a kind of else
expression.
See also choose node.

Attribute Detail
- base
-
this is a generic block attribute that allows URI base redefinition: all
uri attributes used in children nodes of this block will be
relative to this new base definition (except if there is another child block
node that redefines a new base). This is only a convenience attribute in
order to simplify URI specifications. A base attribute must be a valid (well
formed) URI, absolute or relative to another base definition.
- test
-
any valid XPath expression (either absolute or relative to the current node).
Children
- catch, choose, depends, echo, filter, finally, foreach, if, remove, save, sax, source, template, try, variable
