ui:iflang

This element checks whether the current language is the language specified by xml:lang. If the result is true, the inner nodes are expanded and the condition code is set to true; otherwise the inner nodes are ignored, and the conditon code is set to false.

For an overview about multi-language support, see the chapter about Internationalization.

Declaration

Level: Control structure

<!ELEMENT ui:iflang ANY>

<!ATTLIST ui:iflang
          xml:lang CDATA #REQUIRED>

Attributes

xml:lang: Specifies the language to check for.

Sub elements

All page body elements may occur as sub elements.

The l namespace

This element can be abbreviated as follows: Instead of

<ui:iflang xml:lang="TOKEN">TREE</ui:iflang>

one can write

<l:TOKEN>TREE</l:TOKEN>

Example

<ui:cond>
  <l:en>One</l:en>
  <l:de>Eins</l:de>
  <l:it>Uno</l:it>
  <l:es>Uno</l:es>
</ui:cond>

Due to the implementation it is currently not recommended to use the combination ui:cond/ui:iflang as substitute for message catalogues if the number of languages is bigger than a small number (three or four). (May be improved in the future, however.)

Hints

Note that template parameters and bracket expressions within ui:iflang are unconditionally evaluated. See ui:cond for a discussion of the consequences of this fact.
