<x:out select="<string>" escapeXml="<true|false>"/>
Name | Required | Description |
select | True | XPath expression to evaluate and display the result. |
escapeXml | False | Defaults to true. By default if resulting content has any XML or HTML or any other markup language tags, the content will be shown with raw XML or HTML or markup language (we can see the tags as well). If set to false, the XML or HTML will be evaluated and shown. |

This is the tag we use to display the result of the XPath expression to the output. If we want the HTML which is part of the result to be evaluated then we can specify escapeXml as false.
