contains function problem

[Howard Katz]

Note that contains() has several signatures. Your statement:

        where contains( "//Mpeg7:Name/text()", "Moras" )
 
is asking if the literal string, "//MPeg7:Name/text()", contains the literal
text, "Moras". It doesn't. What you want is the statement:
 
        where contains( //Mpeg7:Name/text(), "Moras" )

I ask for the email address for a person who has a <Name> as Moras for
example...

my xquery is the following:

 

xquery version "1.0";

declare namespace Mpeg7="urn:mpeg:mpeg7:schema:2001";

for $x in doc("myPersons.xml")//Mpeg7:Semantics

where contains("//Mpeg7:Name/text()","Moras")

return $x//Email

 

 

none results returned

 

what is my fault?

 

Thanks 

Manolis
