Hi, I'm trying to delete an attribute from an element, but having no luck. I'm about 99% confident that my xpath is correct, is this a bug?
Here is a short example of my code: <xforms:repeat nodeset="instance('metadata')/mods:titleInfo" id="titleInfo"> <xforms:input ref="@displayLabel"> <xforms:label class="mods-label">Display Label: </ xforms:label> </xforms:input> <xforms:trigger class="delete" appearance="minimal"> <xforms:label>remove</xforms:label> <xforms:action ev:event="DOMActivate"> <xforms:delete nodeset="@displayLabel" at="index('titleInfo')"/> </xforms:action> </xforms:trigger> </xforms:repeat>
relevant XML snippit: <mods:mods> <mods:titleInfo type="abbreviated" authority="lcsh" displayLabel="title"> <mods:title>Sound and fury :</mods:title> <mods:subTitle>the making of the punditocracy /</ mods:subTitle> <mods:nonSort>the</mods:nonSort> </mods:titleInfo> </mods:mods>

I believe that the problem is that you don't need the "at" attribute on your delete. In that context, the nodeset will have exactly one node (the desired attribute); the "at" attribute may evaluate to a number greater than one. You generally want to use the "at" attribute with the "index" function when you're selecting the currently indexed element node from a repeat.

I constructed a sample form based upon your original message:
This form seems to have the behaviour for which you were looking. It also works without the "at" attribute (and I still think that *not* including the "at" attribute is the correct approach). Can you see if this form works with your version of the Mozilla Xforms Extension? If it does, then we may need more information to try to determine why your actual form isn't working.
Take care,

I've been testing one of the recent nightly branch builds (2007-08-09-03[0], to be precise). I didn't think there had been any fixes to the delete functionality, but apparently I was wrong. It looks like bug 387738[1] might be related to your problem. You may want to give a nightly branch build a try; I've found them to be pretty stable. If you do, you probably want to go with the latest one[2].
