Trying to get the XML document data as a text for the rule input

Question

Hello, 
 I have a requirement where I want to use the body present in the XML document as text. And use that text as the rule input value. 
 Is there any way to achieve this? 
 Thanks

Hi Atul, 
 You could try to use the function xpathdocument ( docId , expression , prefix ) 
 Check the sample below: 
 If you need the whole node: 
 xpathdocument(addHereAXMLDocId,"ns:root/node","http://www.appian.com/ae/types/2009" ) 
 If you need just the text of one field: 
 xpathdocument(addHereAXMLDocId,"ns:root/node/text()","http://www.appian.com/ae/types/2009" ) 
 The prefix that I added in the sample ( www.appian.com/.../2009) is not mandatory and should be used or not according to your XML input file. 
 Hope this helps you to achieve your goal.
