Question

Below is my xml…

What I am trying to do is using XPATH and count expression.. I want a count of when a date in xml matches Todays date. So for example Todays Date is “2011-05-05”.. Any messages that match this date have a count and return a integer. so answer would be NumberofTodaysMessages = 2.

<Response>
    <run_id>1</run_id>
    <message>
      <timestamp>2011-05-05T10:50:00.46875+00:00</timestamp>
      <event_type>Information</event_type>
      <operation>LoadProjects</operation>
      <error_code />
      <details>LoadProjects request detected</details>
    </message>
    <message>
      <timestamp>2011-05-05T10:50:02.296875+00:00</timestamp>
      <event_type>Error</event_type>
      <operation>Processor.InitaliseDCFiles</operation>
      <error_code />
      <details>some error details</details>
    </message>
    <message>
      <timestamp>2011-11-10T10:50:02.296875+00:00</timestamp>
      <event_type>Debug</event_type>
      <operation>Processor.InitaliseDCFiles</operation>
      <error_code />
      <details>some details</details>
    </message>
  <Response> 

How would I go about this in XPATH??

count(/Response/message/Timestamp[@DateTime.Now()])

C# implements XPath 2.0, right? Then you should have all these functions available.
