xxforms:variable inside xPath declaration?

Hello

Is it generally possible to use Orbeon xforms variables inside xPath? In my sample it's not working and I wonder if its possible at all to write ref declarations like:

<xforms:output ref="$test1/data/text[@language='$test2/language']"/>

Thank you for your help,

Karolin

<xforms:instance id="test1-instance">
<root xmlns="">
<data>
<text language='de'>Hallo</text>
<text language='en'>Hello</text>
<text language='fr'>Allô</text>
</data>
</root>
</xforms:instance>

<xforms:instance id="test2-instance">
<root xmlns="">
<language>en</language>
</root>
</xforms:instance>

<xxforms:variable model="test1-model" name="test1" select="instance('test1-instance')" />
<xxforms:variable model="test2-model" name="test2" select="instance('test2-instance')" />

<xforms:output ref="$test2/language"/>

<xforms:output ref="$test1/data/text[@language='de']"/>

<xforms:output ref="$test1/data/text[@language='$test2/language']"/>

Hi Karolin,

Do you mean the interpolation of $test2 ? Then move it out
of the quotes:

[@language=concat($test2,'/language')]

or something similar may work.

Regards,
Hank

Re: xxforms:variable inside xPath declaration?

Hey Hank,

thank you for your answer.
In the end the ' ' was the problem. Using xxforms:variables you have to write it like this:

<xforms:output ref="$test1/data/text[@language=$test2/language]"/>

Cheers,
Karolin

PS:
concat($test2,'/language') won't work because $test2 is interpreted as String = "fr". So concat($test2,'/language') gives back "fr/language"

<xforms:instance id="test1-instance">
<root xmlns="">
<data>
<text language='de'>Hallo</text>
<text language='en'>Hello</text>
<text language='fr'>Allô</text>
</data>
</root>
</xforms:instance>
