Question

Is it possible to use XPath to select only the nodes that have a particular child elements? For example, from this XML I only want the elements in pets that have a child of ‘bar’. So the resulting dataset would contain the lizard and pig elements from this example:

<pets>   <cat>     <foo>don't care about this</foo>   </cat>   <dog>    <foo>not this one either</foo>   </dog>   <lizard>    <bar>lizard should be returned, because it has a child of bar</bar>   </lizard>   <pig>    <bar>return pig, too</bar>   </pig> </pets> 

This Xpath gives me all pets: '/pets/*', but I only want the pets that have a child node of name 'bar'.

Answer 1

Here it is, in all its glory

/pets/*[bar] 

English: Give me all children of pets that have a child bar
