Filter XML with 2 conditions using JOOX and XPATH (JAVA)

Question

I have many xml files to filter and I need to do it with JOOX. I'm using it with XPATH to filter by one condition but I need at least two conditions, I would like to be a dynamic filtering to which I could add more filters if it's requested, but at least I need two. A priori I don't know the structure of the xml and maybe the two conditions reference to siblings nodes. The structures of my xml are like this:

<Message>
   <Header>
      <SequenceNumber>12345</SequenceNumber>
      <OriginSystem>xxx</OriginSystem>
      <Timestamp>141</Timestamp>
      <ContentType>123</ContentType>
   </Header>
   <OriginCenter>
      <CR id="xx" />
      <LI id="We" />
   </OriginCenter>
   <MessageType>
      <Type1 id="myId">
         <Id>LAV6.OIR.282O</Id>
         <TimeStampValue value="1430275652165" />
         <State>
            <UpToDate value="YES" />
            <InterlockedRoute value="YES" routeType="Itinerario" />
            <Sliding value="NOT" routeType="" />
            <Blocked value="NOT" />
            <Plaques>
               <PlaqueO value="NOT" counter="0" />
               <PlaqueV value="NOT" />
            </Plaques>
            <Dual value="YES" active="YES" />
         </State>
         <Flights number="1">
            <Flight index="1" Id="09070" />
         </Flights >
      </Type1>
   </MessageType>
   <Optionals>
      <Parameter1 name="" value="" />
      <Parameter2 name="" value="" />
      <Parameter3 name="" value="" />
   </Optionals>
</Message>

An example could be: find all the messages where PlaqueV has the property value with value NOT and Blocked has the property value with value NOT .

I would do it knowing the depth of the structure with xpath using: //Blocked[@value='NOT']/../Plaques/PlaqueV[@value='NOT']

How I could do it dinamically without knowing the structure?

Thanks!

Thank you splash58, I finally solved it creating a dynamic string and passing it to JOOX.

I mean: JOOX.$(file).xpath(conditions);

Where conditions is the dynamic string I created using your advice:

Root[.//TAG[@property='value'] and .//TAG[content='value'] and...]
