Groovy script to delete broken references to non-existent images in documents

[Rodrigo de Paula Cunha]

So, I created a groovy script to identify and delete portrait images in our hippo gallery but those images were referenced by documents, now the website displays those images blank and I can see in the document nodes that the references are broken. I tried putting together a script to delete the references but was not successful so far.

Can someone please point what am I missing? the code to remove the image reference node is commented out, I'm just trying to list the broken references for now.

Really appreciate any input! 

Thanks!

well, you are not changing anything...

this:

if (JcrUtils.getNodeIfExists(imagePath, this.session)==null) {

                log.warn "Image reference does not exist: ${imagePath}";

                retVal = true;

                //imageNode.remove();

            }

should probably be something like:

if (JcrUtils.getNodeIfExists(imagePath, this.session)==null) {

                log.warn "Image reference does not exist: ${imagePath}";

                retVal = true;

              imageNode.setProperty("hippo:docbase","cafebabe-cafe-babe-cafe-babecafebabe");

 }

cheers
