HtmlNode.SelectNodes issue

Sep 25, 2009 at 10:04 PM

when i use an Xpath of //element on a particular node, why am I getting all the nodes of the entire document of type //element rather than just the nodes within the node I call SelectNode on?  Is it possible to just query the node with SelectNodes for only childnodes with that element tag?

Yes, it does grab all then nodes in the document. Internally it creates a navigator from the root of the document and then runs the xpath.

One of the new Methods HtmlNode.Descendants(string name) may be more to your liking.

var nodes = thenode.Descendants("input");
foreach(var node in nodes)
  //do something with the node

You can also go a step further and do

var nodes = thenode.Descendants("input")
                   .Where(x => x.Attributes.Contains("type") && 

foreach (var node in nodes)
    //do something with the node

You can also use CreateNavigator but be warned the types it returns are System.Xml types, not HAP types.
