I have an XPath related question. I have a list of XML entries like this:
<NavigationEntry>
<BaseData>
<Name>Entry Name</Name>
</BaseData>
<Relation>
<RelationEntry isDefault="0">
<ParentNavigationEntry>456</ParentNavigationEntry>
<Order>200</Order>
</RelationEntry>
</Relation>
<NavigationEntry>
<BaseData>
<Name>Entry Name</Name>
</BaseData>
<Relation>
<RelationEntry isDefault="0">
<ParentNavigationEntry>123</ParentNavigationEntry>
<Order>200</Order>
</RelationEntry>
</Relation>
The question is: how do I get all navigation entries that has a Field ParentNavigationEntry with the value 456.
I tried
//NavigationEntry//RelationEntry[ParentNavigationEntry="456"]
But this only gives me the RelationEntry Field, but I need the NavigationEntry Field.
Is it possible to solve this with a single XPath query?

//NavigationEntry[
/Relation
/RelationEntry
/ParentNavigationEntry = 456
]
Note: Select those NavigationEntry
elements and then filter predicate. Also, when the schema is well known it's not good practice to use //
because it traverse the whole descendant tree even after a match.

Add /ParentNavigationEntry to your XPath..
Example...
//NavigationEntry//RelationEntry[ParentNavigationEntry="456"]//ParentNavigationEntry
