Question

I wondering what the ‘best practice’ way (in C#) is to implement this xpath query with LINQ:

/topNode/middleNode[@filteringAttribute='filterValue']/penultimateNode[@anotherFilterAttribute='somethingElse']/nodesIWantReturned 

I would like an IEnumerable list of the ‘nodesIWantReturned’, but only from a certain section of the XML tree, dependent on the value of ancestor attributes.

Answer 1

A more verbal solution:

var nodesIWantReturned = from m in doc.Elements('topNode').Elements('middleNode')               from p in m.Elements('penultimateNode')               from n in p.Elements('nodesIWantReturned')               where m.Attribute('filteringAttribute').Value == 'filterValue'               where p.Attribute('anotherFilterAttribute').Value == 'somethingElse'               select n;
