Is it possible to use regular expressions inside of an xpath statement executed by System.Xml.XmlD ocument.SelectS ingleNode() ?

Is it possible to use regular expressions inside of an xpath statement
executed by System.Xml.XmlD ocument.SelectS ingleNode() ?

string sdoc = "<foo><bar a='1'/><bar a='2'/></foo>";
System.Xml.XmlD ocument pdoc = new System.Xml.XmlD ocument();
pdoc.LoadXml(sd oc);
System.Xml.XmlN ode pnode =
pdoc.SelectSing leNode("//foo/bar/matches(.,'\\d' )");
string foo = pnode.InnerText ;
int i23 = 23 + 23;

Yes, when using EXSLT.NET. See

Forgot to mention that latest EXSLT.NET version can found at

EXSLT.NET has nothing to support regular expressions inside of xpath for
System.Xml.XmlN ode xpath methods such as SelectNodes or SelectSingleNod e

These methods are just wrappers around XPathNavigator. Select() method
and you are right, they are useless with EXSLT.NET. Use XPathNavigator
instead. Here is a sample how to use EXSLT function with XmlDocument and
XPath.

XmlDocument doc = new XmlDocument();
doc.Load("foo.x ml");
XPathNavigator nav = doc.CreateNavig ator();
XPathExpression expr = nav.Compile("se t:distinct(//@country)");
expr.SetContext (new ExsltContext(do c.NameTable));
XPathNodeIterat or ni = nav.Select(expr );
while (ni.MoveNext()) {
Console.WriteLi ne(ni.Current.V alue);
}
