Parsing an XML Message

XML is a very common format to transmit data in your messages. It supports schema and can be used with a number of languages and platforms. To work with XML in your message, be sure that the Content Type of your message is set to XML.

In addition to the standard fields that are required for any parser, the following fields are required:

Search Location (required)
By definition the XML will be present in the Message Body, so make sure you specify Message Body as the Search Location

Message Field Type (required) Specify the type of the field as it appears in the message, see Message Field Types for more information.

Storage Field Type (required)
Specify how this value should be stored and the type that is assigned to it, see Type System for more information

Is Required
Check this option if the value must be present on the message. If the value is set to be required, however the value is not present, the message will be rejected

XPath (required)
Parsing XML Messages is done with XPath.

RegEx Value Selector
In addition to providing the initial XPath selector to extract the value you can provide a regular expression to select the value out of the resulting string.

Additional Validation Fields
After the message has been parsed there are a number of options that can be used to validate the value, if validation fails, the message will be rejected.

Using XPath

The following is an example of how you would use an XPath query to select a value

With the following XML document

<?xml version='1.0'?> 

The XPath Expression //root/x would select the value green.

Here is a good tutorial on using XPath.
