For guardian articles, e.g. http://www.guardian.co.uk/environment/2012/aug/14/eu-waste the Meta tags list in "Page Info" contains many entries with blank Name field but non-blank Content fields. Looking at the page source, some likely candidates for the problematic entries are "link rel=canonical", "meta name=description", "link rel=image_src". Tested on Fedora 17 Live image + updated firefox: firefox-14.0.1-1.fc17.x86_64 xulrunner-14.0.1-3.fc17.x86_64

The Guardian webpage claims to be HTML5, but Open Graph uses <meta property="...". In HTML5 the meta tag does not have a property attribute. Open Graph is RDFa so you probably need a different DOCTYPE e.g. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML+RDFa 1.0//EN" "http://www.w3.org/MarkUp/DTD/xhtml-rdfa-1.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="http://rdf.data-vocabulary.org/#">

For this bug, the change will need to be made at http://mxr.mozilla.org/mozilla-central/source/browser/base/content/pageinfo/pageInfo.js?rev=8d3304b7e0e0#514. We currently supply `metaNodes[i].name || metaNodes[i].httpEquiv`. We can update this to also include the `property` attribute: `metaNodes[i].name || metaNodes[i].httpEquiv || metaNodes[i].getAttribute("property")`.

I think instead that you should just add a "property" attribute to nsIDOMHTMLMetaElement.idl so that you can reference it as metaNodes[i].property

Ms2ger, are you OK with doing what comment #3 is recommending?

No, that's nonsense. nsIDOM* interfaces don't expose anything to JS, and haven't for years. getAttribute() is perfectly fine if that's something we want to do. Not sure if we need to expose those, though. What is the use case for this list?

Ms2ger is right. nsIDOMHTMLMetaElement is irrelevant to JS. Adding things to HTMLMetaElement.webidl _could_ be done, but I don't see a good reason to add this there, esp. since it would have to be [ChromeOnly] or something (unless you're proposing this be added to the HTML spec).

Are you asking what's the point of this bug? I thought I added some more background in comment #2 but I guess I forgot to add it there. There are many pages that use name="property" that currently display a blank column in the Page Info dialog. It would be nice if we added support for those pages, and it doesn't come at much of a cost to us if we only have to update pageInfo.js to do so.

Comment on attachment 8567565 [details] [diff] [review] Make pageInfo display the 'property' attribute of meta tags. Review of attachment 8567565 [details] [diff] [review]: ----------------------------------------------------------------- ::: browser/base/content/pageinfo/pageInfo.js @@ +512,5 @@ > var metaTree = document.getElementById("metatree"); > metaTree.view = gMetaView; > > for (var i = 0; i < length; i++) > + gMetaView.addRow([metaNodes[i].name || metaNodes[i].httpEquiv || metaNodes[i].getAttribute("property"), metaNodes[i].content]); This looks good. We'll want to wrap the line after the comma since it's getting pretty long. Do you want to post an updated patch and add r=jaws to the end of the patch summary?

Thanks for the feedback. I implemented the solution described in comment #2 and wrapped the line accordingly. I wasn't entirely sure about the code style conventions (I looked here (https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style), especially regarding the indentation of the wrapped line and the question of whether or not braces should be added. Hopefully I did it correctly.

I'll push this to tryserver where it will run the changes against the set of automated tests that this might affect. If all goes well (which I expect it to), we can land this on fx-team where it will then get merged to mozilla-central and appear in Firefox Nightly a day or two later.
