Regex on onItemChange

Hi ,

I am implementing a functionality where whenever user select any URL in Teamsite DCR , corresponding portal URL should be displayed in DCR. This functionality is working fine using onItemChangein formAPI.

Sample:

IWEventRegistry.addItemHandler("/Root/HomePage/HeroImage/Link/URL", "onItemChange", changeURL);
IWEventRegistry.addItemHandler("/Root/HomePage/Category/Link/URL", "onItemChange", changeURL);

similarly for other DCRs.

I want to make it generic . I have starting "Root" and ending "URL" as common in xpath and rest Xpath is different. So if it is possible I can use any regex expression on this event. I tried using regex for it , but it didn't work (I am new to regex).

Please help me if it is possible to put regex in IWEventRegistry.

Thanks in Advance.

The IWEventRegistry doesn't accept regexes. They're approximations of XPath syntax so I don't know where you came up with that.

What you can do is IWDatacapture.getRoot() and then recursively loop through getChildItems(). For each item, attempt to match its name (path) to your regex and add to the event registry as required.

That said, this is a pretty crappy performance waste especially if you have a lot of fields, so you really should consider spending the extra 5 minutes to be specific about your handler mappings.

Thanks rpoulin for quick response, I just thought to make it generic, to avoid overhead of creating individual item change event for every items, since regex do not work . I will go ahead with my old approach.
