The xpath analytic navigates to a specific element and attribute in the XML using the xpath expression and returns the list of objects that match.

Syntax

xpath(xml content,"xpath expression")

The following table describes the required and optional arguments:

Argument	Required Optional	Description
xml content	Required	Any element that returns the xml content. The element can be a web service analytic that returns an xml document.

Example

WHEN 1 rssnews rn WITH xpath(rn.contents,"/rss/channel/headline") as result contains "World Cup Finalists" then response with body=”${result}”

The following table describes the result for the event property value that you pass:

Event Property Value	Description	Result
