XPATH AND 同一节点上的条件

Question

this is a pretty simple question but I couldn't really find the correct result googling my problem.

I have this part of an xml document

<ProcessTypes>
     <ProcessType>
           <ID>DRUCK</ID>
     </ProcessType>
     <ProcessType>
           <ID>EBOX</ID>
     </ProcessType>
</ProcessTypes>

What would be the correct xpath expression to check if i have both ids "DRUCK" and "EBOX" in my xml file?

Answer 1

This XPath expression,

//ID="DRUCK" and //ID="EBOX"

will evaluate to true iff the XML document has an ID element with string value of "DRUCK" and an ID element with string value of "EBOX" .

Related, but not what was asked:

This XPath expression,

//ProcessType[ID="DRUCK" or ID="EBOX"]

will select all ProcessType elements with ID child elements with string values of either "DRUCK" or "EBOX" .
