No, (a) the path expression must select a node, and (b) it isn't allowed to
use predicates. The combination of these two rules means that you can't use
string functions like concat(). In fact, XML schema allows only a very small
subset of XPath 1.0 in these expressions.

Hello All,
 
Is it possible to specify XPATH functions in XS:field, XML schema element ?
Like 
 
<xs:field xpath="concat('abc','def')/>
 
Thanks and Regards,
Chandu

No. I doubt this is even on anyone's requirements list - element names are
generally regarded as atomic, and the idea that individual characters in the
name should have semantic significance feels all wrong. That's what
attributes are for.

In the XSD is it possible to specify, if the element value is "X" and the
following elements must start with ?



For Ex:

<Tasks>

<Task>

<Name>X</Name> 

<Xlong>long text</Xlong>

<Xshort>short test</Xshort>

</Task>

<Task>

<Name>Y</Name> 

<Ylong>long text</Ylong>

<Yshort>short test</Yshort>

</Task>

</Tasks>

Thanks and Regards,
