contains function problem

[Manolis Mylonakis]

hello,

i have a problem with 'contains' function of xquery.

I have the following xml file named myPersons.xml





<Mpeg7 xmlns="urn:mpeg:mpeg7:schema:2001" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

<Description xsi:type="SemanticDescriptionType">

<Semantics>

<AbstractionLevel dimension="0"/>

<Label>

<Name>Soccer Agent Example</Name>

</Label>

<Property>

<Name>Something</Name>

<Definition>socceragents</Definition>

</Property>

<SemanticBase xsi:type="AgentObjectType" id="Moras">

<AbstractionLevel dimension="0"/>

</Mpeg7>











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
