• lambda filters

  Hi I currently use this lien to remove xml emelents and their childs.. xmldoc.Elements("book").First(Function(b) CInt(b.Attribute("id")) = ArticleID).Remove() But I now need to filter out based on two more attributes, so I would also like to do like this... Function(b) CInt(b.Attribute("LID")) = LID Function(b) CInt(b.Attribute("VID")) = VID But that does not work, how do I do that?
