Create a message validation cartridge that can be used by Smooks to perform message validation. ----------------------------------------------------------------------------------------------- Key: JBESB-459 URL: http://jira.jboss.com/jira/browse/JBESB-459 Project: JBoss ESB Issue Type: Feature Request Security Level: Public(Everyone can see) Affects Versions: 4.0 Reporter: Tom Fennelly Assigned To: Tom Fennelly Priority: Optional Fix For: 4.2 Something as simple as cartridge that would allow you target and apply regexp and XPath expressions at parts of a message, generating error/warning reports. I actually used Smooks to prototyped something that's conceptually similar from a validation perspective - analyze a website using Smooks, and generate a report contain possible browser issues with each page (message) e.g. on browser "X" on Mac Os X, this part of the markup may cause usability issues etc (http://milyn.codehaus.org/Smooks+Report+Generator). The cartridge could allow you create "validation" resources that can be targeted at message exchanges (fragments, elements, attributes etc). This might support applying regexp expressions to data values (match, not-match etc - easy enough) as well as using xpath (has-child-element etc easy enough too *I think*). Would obviously get more difficult if you started to add some form of expression language to it - "if attribute matches X and doesn't have child element Y" etc. Might be possible to use JBoss Rules and some form of DSL to wrap the xpath stuff (or even the regex stuff too).
