Currently, I am working on a program that converts an html page into a PDF using the iText Library.
The Checker that I am using is PAC3 -->PDF Accessibility Checker 3 which is described by the following link (https://section508.gov/blog/check-pdf).
One of the issues is the “Alternate description missing for an Annotation”
An excerpt from the following link explains it:
http://www.uottawa.ca/respect/sites/www.uottawa.ca.respect/files/fss-fixing-accessibility-errors-in-pdfs.pdf
Alternative description missing for an annotation This usually happens when the link is not clear enough. To fix this error, add alternative text to the link tags. To add the alternative text, please do the following;
In the tag tree, select the tag for the link, and select Properties
from the options menu.
In the Touchup Properties dialog box, select
the Tag Tab.
Type alternate text for the link, and click close
I have been trying to use iText to fix this problem, but googling, looking at the source and reading the documentation does not help.
Does anybody have any suggestions on how to either write the HTML or use the itext problem to get rid of the “Alternate description missing for an Annotation”
Thank you for your help
You did not specify whether you using old code (XMLWorker, HTMLWorker) or new iText code (pdfHTML).
This of course impacts the proposed solution.
In my answer I am going to assume you are using pdfHTML
There are several options:
edit the incoming HTML using a library like JSoup
convert the incoming HTML to iText IElement objects, and edit those, setting properties where needed
write your own custom TagWorker that handles all instances of a specific tag, and write custom logic to deal with the missing annotations.
An example of a custom tag worker can be found here:

After searching for a while as I couldn't find a way to achieve what I want posting the question here. I want to format the angular HTML file in a way that is explained below.
There was enough way to format. Using extensions or overwriting the vscode settings by "html.format.wrapAttributes": "force"
This is how the file is formatted after pressing Ctrl+Shift+Enter
I want only the angular component selectors' attributes to be formatted as shown below.
Any extensions or customizations or any better way to do that is appreciated?
I had the same issue and found a solution.
Install Beautify plugin for vscode and it will solve your issue.
You can use the following option in VS Code settings:
"html.format.wrapAttributes": "preserve-aligned"
If you split the angular components' attributes into different lines (and keep the remaining HTML attributes in a single line), it will correctly format you document without breaking the "rules" you defined.
Yes, it has a bit of manual work, but is the best alternative I've found.
I used Ctrl + K + S for the first time and after that it continued saving withoud reformatting
So, I was taking a look at some websites that display video on their front page, and I came across this website. I wanted to know how they had accomplished such a remarkable result, so I inspected the element that contained the video. To my surprise, I encountered html attributes I had never seen before.
My question is: If this is not standard html, then what is it?, and how can I use it?
Here is a snippet of the code they are using:
<div class="frontpage-head-wrapper" data-has-video="1" data-video-mp4="http://d27shkkua6xyjc.cloudfront.net/videos/maaemo-film-2.mp4?mtime=20141113185431" data-video-ogv="http://d27shkkua6xyjc.cloudfront.net/videos/maaemo-film-2.ogv?mtime=20141113185421">
</div>
A point before I answer your question is that the data attributes are custom attributes in which user can store any data. These were introduced in HTML5. For more information please refer to this
From what I understand looking at the code link https://developer.mozilla.org/en/docs/Web/Guide/HTML/Using_data_attributes
Now to your question
what happens is that the website is using custom data attributes and the custom attributes specifies the url where the video is stored. And when I dug further in the code, I found that they are displaying video using ajax calls
Those are data attributes. They are useful because they are standardized, and
allow easy JavaScript access:
ch = document.querySelector('div').dataset;
// 1
ch.hasVideo;
// http://d27shkkua6xyjc.cloudfront.net/videos/maaemo-film-2.mp4?mtime=20141113185431
ch.videoMp4;
// http://d27shkkua6xyjc.cloudfront.net/videos/maaemo-film-2.ogv?mtime=20141113185421
ch.videoOgv;
Using data attributes
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.
I have an HTML string that I need to modify its elements.
I looked into NSXMLParser, but didn't see any method to modify the elements while reading them.
I don't like the solution of creating a NSMutableString and adding strings to it.
Is there a way to read HTML string and modify its element in an elegant way?
e.g.,
<div style="color:grey"></div>
will be
<div style="color:black"></div>
Unfortunately I saw that one cannot use NSXMLDocument in an iPhone app.
see the github project KissXML which is a 'clone of NSXML library and works the same.
https://github.com/robbiehanson/KissXML
shameless self-advert: my fork of it works way better with html that's not real xml

I write an application and inside of HTML code I have custom tags (of course these tags are parsed on server side and end user gets them as valid HTML code). Example of custom tag usage:
<html>
<body>
...
<Gallery type="grid" title="My Gallery" />
...
</body>
</html>
1.) How can I have eclipse recognize my custom tags inside of HTML code and add syntax highlighting to them?
2.) How can I add auto-suggestions to my custom tags? For example if I type "<Gallery " press "Ctrl+Space" - in the list of available attributes it shows me "type" and "title" and if I type "<Gallery type=" press "Ctrl+Space" I would see list of available values only for tag "Gallery" and its attribute "type".
Thanks in advance!
Not really what you want, but maybe it helps you:
You can try the Aptana Plug-in for Eclipse. It allows to write your own regular expression for HTML validation, so a custom tag would be ignored by the validator.
E.g.:
.gallery.
Eclipse allows you to add simple auto-suggestions via Templates. On
Eclipse 3.7.1 (Indigo) + PHP Dev Tools (PDT) 3.0.0: Window > Preferences > Web > HTML Files > Editor > Templates
Sadly, there is no easy way: you have to roll your own parser for this, and then add both your extra elements and the base grammar (HTML) to it.
If you have your parser, you could use it to do syntax highlighting (strictly speaking, for that simple lexing is enough); and a good parser can support content assist (auto-suggestions in your terminology).
Caveats:
Creating a parser for HTML is not an easy task. Maybe by aiming at a more often used subset is feasible.
If a parser exists, the editor parts are still hard to get well.
Some help on the other hand: you could use some text editor generators to ease your work:
Eclipse IMP http://www.eclipse.org/imp/ can in theory handle any type of parser, but currently it is most optimized for LPG. The documentation is scarce, but the developers are helpful in the forums.
Xtext http://www.eclipse.org/Xtext/ got quite a hype for creating text editors for DSLs. The generated editors are quite nice out of the box, but is not the best solution for large files. Has a really helpful developer community.
EMFText http://www.emftext.org/index.php/EMFText is a lesser known entity - I don't know it in details, but I guess, it is similar to Xtext.
I know its been a long time since this Q was asked,
but I hope this might help others like myself that reach this in search of a solution.
So, When using Eclipse (Mars.1 Release (4.5.1) - and possibly earlier - I did not check).
Go to Window - Prefrences
Then in the dialog that opens go to Web - HTML Files - Editor - Validation.
On the right side:
under Ignore specified element names in validation and enter the list of custom elements you use. (e.g. Gallery,tab,tabset,my-element-directives-*)
you might also like to go under Ignore specified attribute names in validation do the same for your custom attributes.(e.g. ng-*,my-attr-directives-*)
Two things to note:
After letting eclipse do a full validation you must also close the file and reopen it to have the warnings removed from the source code.
Using this method would ignore those attributes under any element. I don't think there is a simple way to tell it to ignore some-attribute only if its a child of some-element.
I find templates are an ok alternative but let's see if we can encourage a more robust solution; please take a moment and vote for this: https://bugs.eclipse.org/bugs/show_bug.cgi?id=422584
You need to add a new HTML template.To add a new template, complete the following steps:
1) From the Window menu, select Preferences.
2) In the Preferences page, select Web and XML > HTML Files > HTML Templates.
3) Click New.
4) Enter the new template name and a brief description of the template.
5) Using the Context drop-down list, specify the context in which the template is available.
6) In the Pattern field, enter the appropriate tags, attributes, or attribute values (the content of the template) to be inserted by content assist.
7) If you want to insert a variable, click the Variable button and select the variable to be inserted. For example, the word_selection variable indicates the word that is selected at the beginning of template insertion, and the cursor variable determines where the cursor will be after the template is inserted in the HTML document.
8) Click OK to save the new template.
You can edit, remove, import, or export a template by using the same Preferences page.
