Since the & is in CDATA tags, I am not sure this is your problem. What is the error you are receiving?

Maybe you are right :)

I get this error:
Error parsing XSLT file: \xslt\BlogListPosts.xslt

An error occurred while parsing EntityName. Line 2, position 47.

Actually, it seems more likely that the "bug" is in the to methods in umbraco.editorControls.tags.library?

The XSLT calls both of these methods, and the error only appear if I have used a tag with ampersand in one of the blogposts...

the error occurs at umbraco.editorControls.tags.library.getTagsFromNode(String nodeId) and at umbraco.editorControls.tags.library.getAllTagsInGroup(String group) so it seems to me at this is indeed a bug.

I made a workitem for this http://umbraco.codeplex.com/workitem/27650 so please vote.

Am i correct in thinking that as the tags datatype is part of the core fixing this would involve amending the core source code? Really don't want to do this but can't see a work around. I was considering a SQL Server trigger?

Has anyone else found a work around? Whenever anyone enters & in a tag the site breaks.

I can't see any event handlers for tags.

I'm having the same problem, how did you fixed it?

I'm having the same problem in Umbraco 6.0.2.  Blog4Umbraco breaks when the user puts in a tag with an ampersand (&).  This either needs XML encoding on the way into the database or encoding properly by the getAllTags function in umbraco.editorControls.dll

Hi Kris

Could you try and post the code snippet that is rendering your content?
