May I ask the circumstances in which you need to do this...Hover your mouse over the MRI bookmarklet on IE browser and observe that the Java Script code which is helping us in validating the XPath Expressions and CSS Selectors locators will be displayed as shown below: Conclusion MRI is nothing but a bookmarklet containing the Java Script code for validating the XPath Expressions and CSS Selectors locators in Internet Explorer Browser.If you requirement is to validate the XPath Expressions and CSS Selectors Locators in Internet Explorer browser, blindly use MRI bookmarklet.It only verifies that the XML document is well formed. Message) End Try End Sub Shared Sub Schema Validation Handler(By Val sender As Object, By Val e As Validation Event Args) Select Case e.

If you are not aware of these plug-ins, you can refer to important ones in the below links: Now its time for Internet Explorer browser.Errors in XML documents will stop your XML applications.The W3C XML specification states that a program should stop processing an XML document if it finds an error.XPath was defined by the World Wide Web Consortium (W3C).The XPath language is based on a tree representation of the XML document, and provides the ability to navigate around the tree, selecting nodes by a variety of criteria.
