RBeL-Path is a XPath or JSON-Path inspired expression-language enabling the quick traversal of captured RBeL-Traffic (navigation of the RbelElement-tree). It is described in detail here.

Some examples:

• $.body The body of the message
• $..Action All nodes named "Action" (searches the whole tree)
• $.body..Action All nodes named "Action" in the body.
• $..[?(content =~ "UTF-.*")] All nodes matching the given JEXL-Expression. (Here: All nodes that have text starting with "UTF-")

The JEXL syntax is described in detail here.

When executing a JEXL-Expression the context is initialized with a multitude of values, helping you write short and powerful JEXL-Expressions. In addition, you can always use RbelPath expression, which are described here.

Some examples:

• "RbelHttpMessageFacet" =~ facets Checks if the message has the "RbelHttpMessageFacet" facet. facets is an array which contains all facets recognized by the RbelConverter.
• isRequest Checks if the message is a request.
• $.body.recordId == "X12349035" Checks for the recordId of a decrypted EPA-VAU-message.
• $.header.Content-Type == "application/json" Check if the message is a JSON-message.
• charset =~ "UTF-.*" Check the charset with a regex.
• $.body.recordId == "Y243631459" && charset == "UTF-8" Combines the two criterions.
