RE: Nasty XPath expressions
I'm not sure how closely this mirrors the behavior of .valueOf, but I often use: node.SelectSingleNode(strXPath).InnerXml This works with the native MSXML and managed .NET classes, and gives you whatever the value of the selected element or attribute is. You have to cast it to the appropriate type if you want something other than a string; you could probably get the type from the SOM if there is an XSD associated, but I never bothered. > -----Original Message----- > From: Francis Norton [mailto:francis@r...] > Sent: Friday, December 14, 2001 10:13 AM > To: Christian Nentwich > Cc: xml-dev > Subject: Re: Nasty XPath expressions > > > > Christian Nentwich wrote: > > > On Fri, 2001-12-14 at 14:42, Steve Muench wrote: > > > >>Oracle's XML Parser also provides an XPath engine that's > >>woven into our DOM implementation.
