How to search for a property Attribute in AML?

In AML: I would like to search for an Item of type Action, with a Property hum_project_id

<Item type="activity2" action = "get" select="hum_project_id">
<id>00004C85E3B74A7D995A48B536924853</id>
</Item>

I would like to change this to search the Item Property hum_project_id.keyed_name like '2SV%'. How do I do this?

<Item type =" Activity2 " typeId =" E236DB697E294C46B630C99A0D20C2B1 " id =" 00004C85E3B74A7D995A48B536924853 " >
  < hum_project_id keyed_name =" 2SVA-19107-001 " type =" Project " > 528575AAF3BC4A01ABE1DAA0991C0C3F </ hum_project_id > 
  < id keyed_name =" EUNA 3 - Specification Gateway " type =" Activity2 " > 00004C85E3B74A7D995A48B536924853 </ id > 
 </Item>
