XML Modifiers

Use XML modifiers to pull pieces of XML data into CSM in a usable format. For example, use XML modifiers with webhooks to parse, change, and use data between an external tool and CSM.

XML modifiers build on each other and typically must be used in conjunction with each other to return useful values. In addition, field tokens can be used in the modifiers. See also Webhook Modifier Examples.

Note: All XML should be inside a root container so that you can use modifiers to successfully find it. Encapsulate the entire list in a root container as follows:

<directory><name id=”bob”>Value</name><name id=”Jane”>Value</name></directory>

The following modifiers can be applied to XML data. The examples use an XML collection that contains a list of books.
