HTML rel="up" attribute? - html

I'm using mobile template HTML files on a PHPBB forum.
I tested the html for errors at http://validator.w3.org/
The test results showed the following error
Line 24, Column 66: {navlinks.FORUM_NAME}
Bad value up for attribute rel on element a: The string up is not a registered keyword or absolute URL.
Not having heard back from the author and not finding much on Google search, I'm trying to understrand what rel="up" does, if anything constructive.
Can't find any mention as an official HTML attribute
http://www.w3schools.com/tags/att_link_rel.asp
wondering if it's probably safe to just remove the phrase rel="up"

The Internet Assigned Numbers Authority (IANA) keeps a list of link relationships The latest version is from March 21 2013.
up: Refers to a parent document in a hierarchy of documents.
Unfortunately, despite the fact that this registry was long established, it was decided that HTML5 would not use this registry and would use a Wiki page to list the conforming link types instead.
Up, is listed in a rather insane section marked "dropped without prejudice", which nobody seems to know what to do with, or how to get those link types out of.
It's safe to drop it, but some browsers and browser plugins make use of it. For example, I use a Firefox plugin called "Link Widgets" like this to make use of the link type.

From: http://www.w3.org/MarkUp/html3/dochead.html
REL=Up
When the document forms part of a hierarchy, this link references the immediate parent of the current document.
If this is causing any specific problems or unexpected results, please post your code. Thanks.

What is tppabs attribute?

As the title suggest, I've encountered this tag today. Searched for it, however couldn't find anything informative. It is something like this
<a href="activities.html" tppabs="http://www.dreamguys.co.in/hrms/activities.html">
What is the meaning of "tppabs" attribute?
From:
http://www.tenmax.com/teleport/support.htm
Q: I notice that the HTML pages Teleport creates will have "tppabs" tags in them. What are these and can I remove them?
A: The tppabs tags are created and used by Teleport as part of its Link Localization system. You can prevent the tags from being inserted by turning OFF Link Localization on the Project Properties, Browsing/Mirroring page; but then the links between files may not work correctly in the offline copy.
This is not a default attribute and will more than likely be a custom created attribute, you will need to look at your code to find out more.
Elements (like div and a) have starting and ending tags, and starting tags can contain attributes.
As for the status of tppabs, it has never existed. It's inserted into markup by Teleport Pro and contains the absolute form of a URL. This allows the software to locate a resource once the document has been downloaded. It serves no purpose as far as HTML is concerned.

Capybara won't find a button by its "name" attribute

A W3C-validated HTML 5 web page contains this working, simple button inside a login form.
<input data-disable-with="Signing in, please wait&hellip;"
name="commit" type="submit" value="Sign in" />
I'm writing a largely pointless test :-) in a Rails 3.2.17 application that's just to get the hang of Capybara and I've already got completely stuck Googling, reading documentation and reading source code to the test framework, with no joy - attempting to find this button by its name (i.e. "commit") fails.
click_button("commit")
find_button("commit")
Both result in Capybara::ElementNotFound: Unable to find button "commit". If I use the visible button text of Sign in then the element is found, i.e. these:
click_button("Sign in")
find_button("Sign in")
...both work fine, so it would appear that the XML parser isn't having any trouble finding the element.
Documentation for click_button says that the locator works on "id, text or value", with "text" being meaningless for an input element like this (the visible text is taken from the value attribute), but relevant perhaps for button elements. So, we might expect that to fail, though if we view the code via the documentation, find that it calls down to find in the same way as find_button. Yet find_button is documented differently; it says it locates by "id, name or value". So sadly, we know from this that the documentation is broken because it says two different things for what turns out to be an identical call at the back end.
Either way, the element isn't found by name, and that means the lower level find call isn't searching name attributes as far as I can see. This means Capybara (2.2.1, on Nokogiri 1.6.1) is rather broken in that respect. How come nobody has noticed? I've Googled for ages and it doesn't seem to come up. I seem to be rather missing the point :-)
Why don't I just search for the English text in the button, you might ask? Because of internationalisation. This old, Rails 1 -> 2 -> 3 upgraded app has some I18n parts and other static text parts. I don't want to be forced to put I18n into any view that Capybara tests, just so I can have the test use I18n.t() to ensure a match despite different languages or locale file updates. Likewise, it would clearly be very stupid in 2014 to write hard-coded English strings into my tests.
That's why we have names and IDs and such... The unique (in theory!) identifiers that are machine-read, not human-read.
I could hack up something that CSS-selected by "type=submit" but seriously, why isn't Capybara searching the name attribute when its documentation says it does, and why does the documentation disagree on what attributes are searched on two methods that call down to exactly the same back-end implementation with exactly the same parameters?
TIA :)
It turns out the docs are misleading for both calls, as neither look at the attributes listed. It's also clearly very confusing what exactly a "button" means, since a couple of people herein seemed to think it literally only meant an HTML button element but that's not the case.
If you view the source for the documentation of, say, click_button:
https://github.com/jnicklas/capybara/blob/a94dfbc4d07dcfe53bbea334f7f47f584737a0c0/lib/capybara/node/actions.rb#L36
...you will see that this just calls (as I've mentioned elsewhere) to find with a type of :button, which in turn passes through to Capybara's Query engine which, in turn, ends up just using the standard internal selection mechanism to find things. It's quite elegant; in the same way that an external client can add their own custom selectors to making finding things more convenient:
http://rubydoc.info/github/jnicklas/capybara/master/Capybara#add_selector-class_method
...so Capybara adds its own selectors internally, including, importantly, :button:
https://github.com/jnicklas/capybara/blob/a94dfbc4d07dcfe53bbea334f7f47f584737a0c0/lib/capybara/selector.rb#L133
It's not done by any special case magic, just some predefined custom selectors. Thus, if you've been wondering what custom selectors are available from the get-go in Capybara, that's the file to read (it's probably buried in the docs too but I've not found the list myself yet).
Here, we see that the button code is actually calling XPath::HTML.button, which is a different chunk of code in a different repository, with this documentation:
http://rdoc.info/github/jnicklas/xpath/XPath/HTML#button-instance_method
...which is at the time of writing slightly out of date with respect to the code, since the code shows quite a lot more stuff being recognised, including input types of reset and button (i.e. <input type="button"...> rather than <button...>...</button>, though the latter is also included of course).
https://github.com/jnicklas/xpath/blob/59badfa50d645ac64c70fc6a0c2f7fe826999a1f/lib/xpath/html.rb#L22
We can also see in this code that the finder method really only finds by id, value and title - i.e. not by "text" and not by name either.
So assuming XPath is behaving as intended, though it's not clear from docs, we can see that Capybara isn't documenting itself correctly but probably ought to make the link down to XPath APIs for more information, to avoid the current duplication of information and the problems this can cause for both maintainers and API clients.
In the mean time, I've filed this issue:
https://github.com/jnicklas/capybara/issues/1267
You can also use css selectors which are default capybara locators. People say they are faster.
find('[name=commit]').click
Capybara do not look at name attribute in it's finders :(
You can use xpath selector if you want
find(:xpath, "//input[contains(#name, 'commit')]").click()
If anyone wants it is possible to add (quite easily) find by name selector. In order to do so:
Add following code to test/test_helper.rb (for minitest)
Capybara.add_selector(:name) do
xpath { |name| XPath.descendant[XPath.attr(:name).contains(name)] }
end
Use it
Now in your tests you can use following selector:
find(:name, 'part_of_the_name_attribute')
It will find every element which name attribute contains searched value.
Example
find(:name, 'user')
This will find elements (element could be of any type):
<select name='user_name'>
<input name='name_of_user'>
<textarea name='some_user_info'>
You can use this selector to find a button on a page with RSpec and Capybara:
expect(page).to have_selector(:link_or_button, "Button text")
Check your gem depencies. RSpec 3 or higher works with gem 'rspec-rails', '~> 3.7.1' then capybara version must be gem 'capybara', '~>2.18.0' and poltergeist should be gem 'poltergeist', '~>1.17.0'.

Author error inside Google Structured Data Test

I receive this error when analyzing a review of my website: "Missing required hCard "author""
http://www.google.com/webmasters/tools/richsnippets?q=http%3A%2F%2Fwww.gamempire.it%2Fcastlestorm-ps-vita%2Frecensione%2F131419
Why? I have setted the class="author" inside the html.
This is the code of the page: https://gist.github.com/anonymous/7675765, that you can find here: http://www.gamempire.it/castlestorm-ps-vita/recensione/131419
author vcard has to be inside the hentry element http://microformats.org/wiki/hentry or you have to use the include pattern http://microformats.org/wiki/include-pattern, but I am not sure if it is supported by Google...
you are declaring author a few times in that document...not sure if you want to use microformats, schema.org, or both?
you have markup for both, and one of the author classes is actually nested inside the other...so at the very least that is not correct....fix your nested authors first. if that doesn't resolve validation, come back and share. the solution(s) are relatively easy, but impossible to give you the correct one without knowing more.
The solution is to create a new user mentioning him as Author in Admin Access, then open a page and go to screen option and select author. Now in the page check for author and update it with the new author user which you already created.

Why can't I add an HTML custom attribute to a visualforce page?

I have an control, to which I want to add a custom html attribute called, previousValue.
The Salesforce Developer's Guide assures me that I can do this by prefixing the attribute name with html-.
So I have an element that appears thus:. I also have the docType="html-5.0" attribute in my page control.
However, in Eclipse I get an 'unsupported attribute' error. I have upgraded to the latest force.com IDE; can any one tell me why this isn't working? What else do I need to do?
Thanks.
After much experimentation, the answer to this seems to be that the salesforce developer's guide is inaccurate and the 'hmtl-' prefix is not supported by the <apex:inputField> component. I can add it without a problem to an <apex:outputPanel> component. Don't understand why this should be so and the whole point to using these attributes is to locate data in a relevant place and avoid complex jquery selects to find the data relative to the location at which it is required.

Validation error with skype toolbar

Morning!
I added the following line of code to disable the skype feature on phone numbers.
<meta name="SKYPE_TOOLBAR" content="SKYPE_TOOLBAR_PARSER_COMPATIBLE" />
The problem is that it is causing the following error.
Line 6, Column 71: Bad value SKYPE_TOOLBAR for attribute name on element meta: Keyword skype_toolbar is not registered.
Syntax of metadata name:
A metadata name listed in the HTML specification or listed in the WHATWG wiki. You can register metadata names on the WHATWG wiki yourself.
Is there a work around for this? I need to ensure that the skype numbering doesn't take over the phone numbers but also validate at the same time.
Thanks for reading.
You can submit a metadata registration to the WHATWG wiki as instructed, or you can ignore the error message. Neither of these has any effect on whether your page works as intended.
Use HTML 4.01 (which lacks the HTML 5 draft's bizarre limits on what constitutes valid meta data).
