xml - How to join to predicates together to get an attribute from the parent element based on two attributes and values from child -

-

i need "date of birth" node value when attribute "benefit type id" equal "ben13" and attribute "dependant of benefit" equal "y".

xml

<component> <attributes name="flexdependants">     <attribute name="datainstance">11</attribute>     <attribute name="rownumber">1</attribute>     <attribute name="date of birth">nov 11 1978</attribute>     <component name="allocation">         <attributes name="allocation">             <attribute name="datainstance">24</attribute>             <attribute name="benefit type id">ben13</attribute>             <attribute name="dependant of benefit">y</attribute>         </attributes>     </component> </attributes> <attributes name="flexdependants">     <attribute name="datainstance">10</attribute>     <attribute name="rownumber">2</attribute>     <attribute name="date of birth">oct 12 1984</attribute>     <component name="allocation">         <attributes name="allocation">             <attribute name="datainstance">23</attribute>             <attribute name="benefit type id">ben13</attribute>             <attribute name="dependant of benefit">n</attribute>         </attributes>     </component> </attributes>

so need have 2 predicates in 1 statement, i'm not sure how that..

i've tried: 

/component/attributes/component/attributes/ attribute[@name='benefit type id' , text()='ben13'][@name='dependant of benefit' , text()='y']/ ../../../attribute[@name='date of birth']

^ doesn't work.

the problem joining 2 predicates together... work fine individually not together. how can this?

you can try way (formatted readability) :

/component /attributes[     component     /attributes[         attribute[@name='benefit type id' , .='ben13']              ,          attribute[@name='dependant of benefit' , .='y']     ] ]/attribute[@name='date of birth']

or 1 using less nested predicate maybe easier read :

/component /attributes[     component/attributes/attribute[@name='benefit type id' , .='ben13']          ,      component/attributes/attribute[@name='dependant of benefit' , .='y'] ]/attribute[@name='date of birth']
