    Blog4Umbraco ampersand

     

    Hi all

    I'm breaking my head over this one so if anyone could help me with this, that would be awesome.

    I'm using the Blog4Umbraco package. When a user tags a blogpost with an ampersand (for example: Tips & Tricks), the BlogListPost.xslt and the BlogCategories.xslt breaks. There are more posts on this forum about this topic but none of them are answered.

    Any help would be appreciated!

    Here's the error I'm getting:

    Hi Thijs

    How do you fetch the blogposts in XSLT? You should probably do a replace on "&" so that it gets replaced with "&" I could imgine...

    Hi Thijs,

    This is definitely a bug (and sadly, a very common bug when dealing with XML). An ampersand has special meaning in XML (and HTML for that matter - XML just has more draconian error handling) and it *must* be escaped whenever it's used in a plain text meaning. The input control should handle this. 

    If the tagging mechanism is part of Blog4Umbraco you should report the error to that project, otherwise if it's internal to Umbraco (i.e., does it happen using the "standard" tagging datatype?), it should of course be reported there.

    You can, as Jan suggests, probably work around it, but "fixing the wrong problem" is not really the best solution...

    Thanks both of you. It's in the tagging of umbraco self. I'm trying to validate the tags with a regex but for some reason it doesn't validate. Thanks anyway for your input!
