XML starts-with function

[AlaeddineJebnoun90723]

Hello,

How can test if java code variable ($VARIABLE) starts-with a string in XML code.

When I used when attribute like this: 

<group when="{starts-with({$PROVIDER_NAME},'voip')}">
....
</group>

I got the following error:

only one XPATH expression: '{starts-with({$PROVIDER_NAME},'voip')}' allowed in 'when' attribute

Try removing the curly brackets around the variable $PROVIDER_NAME inside the when-expression.
