Fw: How to query dataObject that is from dynamic type by xpath?

[lizt]

Hi,
    append some comment:
    My dataObject converted to xml like as follow:
    <Entity:EntityType xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; 
xmlns:Entity="com/hollycrm/platform/metadata/model/EntityMetadata.xsd" 
xsi:type="Entity:EntityType">
        <field xsi:type="Entity:SimpleFieldType">
            <name>id</name>
            <dataType type="VARCHAR" length="15"/>
            <isPK>true</isPK>
            <persistAspect>
                  <columnName>ID</columnName>
                  <sqlType>12</sqlType>
            </persistAspect>
        </field>
        <field xsi:type="Entity:LookupFieldType">
            <name>monitor</name>
            <dataType type="VARCHAR" length="30"/>
            <isPK>false</isPK>
            <persistAspect>
                  <columnName>MONITOR</columnName>
                  <sqlType>12</sqlType>
            </persistAspect>
        </field>
        ...
    </Entity>
    
    my question is how to query field dataObject with 
xsi:type="Entity:LookupFieldType" by using xpath.

thanks
