I am trying to learn iMacros (and avoid jscript or vbscript IF possible). I was reading any resource i could find since yesterday and the imacros reference does not have any helpful example of what i need.
All the methods I tried, will extract either the TXT or the HTM content of an element. My problem is that i have a div like this
<div class="cust_div" id="Customer_45621">
...content in here...
</div>
And the part i need to extract is 45621 which is the only dynamic part of the id attribute.
For example, between 3 customers, it could be
Customer_45621
Customer_35123
Customer_85663
All I need is the number. Thanks.
The solution is
TAG POS=1 TYPE=DIV ATTR=cust_div EXTRACT=HTM
Then you have to use EVAL and use in it JS scripting to extract the id. That is the only way. You can't cut the HTML code without JS, but you can use JS in iMacros with EVAL.

I was looking in HtmlPurifier documentation, but I can't see nothing about that.
Let's say I have
<div class="codebox">
All html tags here - Even <div class="codebox">another code box</div>
</div>
I want to parse the content of the first <div class="codebox"> so it can be readable as plaintext.
Can htmlpurifier do that ?
Out of the box HTMLPurifier can't do that and there is no config setting, that I know of, that can convert only the first <div> tag to plain text without converting the entire document. And even for converting the entire document to text the HTMLPurifier is neither needed nor recommended.
You can extend functionality of HTMLPurifier but unless you are an expert coder, I wouldn't recommend doing that.
However if you want to convert a part of the HTML document to text then break it into parts and run the part which you want to convert to text through
strip_tags()
PHP Manual page on strip_tags
You could convert all the div tags in your document to plain text with this configuration directive:
$config->set(HTML.ForbiddenElements, 'div'); //This will black list 'div' tag
And if you absolutely insist on converting your entire document to text using HTMLPurifier then here is the config directive that will do that.
$config->set('HTML.Allowed', ''); //This will white list NO tags ''
With a grails app and from a local database, I'm returning some text in a xml format.
I can return it well formed in a <textarea></textarea> tag with the correct indenting (tabulation, line return,...etc.)
I want to go a bit further. In the text I'm returning, there are some <img/> tags and I'd like to replace those tag by the real images themselves.
I searched around and found no solution as of now. I understood that you can't add an image to a textarea (other then in a background), and if I choose a div tag, I won't have the indenting anymore (and therefore, harder to read)
I was wondering if using a <g:textField/> or an other tag from the grails library will do the trick. And if so, How can I append them to a page using jquery.
For example, how to append a <g:textField/> in jquery. It doesn't interpret it and I get this error
SyntaxError: missing ) after argument list [Break On This Error]...+doc).append("<input type="text" id="FTMAP_"+nb_sec+"" ...
And in my javascript file, I have
$("#FTM_"+doc).append("<g:textField id='FTMAP_"+nb_sec+"' ... />
Any possible solutions ?
EDIT
I did forget to mention that my final intentions are to be able to modify the text (tags included) and to have a nice and neat indentation so that it is the easiest possible for the end user.
You are asking a few different questions:
1. Can I use a single HTML tag to include images inside pre-formatted text.
No. You will have to parse the text and translate it into styled text yourself.
2. Is there a tag in the grails standard tags to accomplish this for me?
No.
3. How can I add grails tags from my javascript code.
Grails tags are processed on the server-side, and javascript is processed on the client. This means you cannot directly add grails tags via javascript.
There are a couple methods that can accomplish the same result, however:
You can set a javascript variable to the rendered content of a grails tag. This solution is good for data that is known at the time of the initial request.
var tagOutput = "${g.textField(/* etc */)}";
You can make an ajax request for the content to be added. Then your server-side grails code can render the tags you need. This is better for realtime data, or data that will be updated more than once on a single rendered page.
Anyone who's done anything much with PHP and receiving rich-text input from something like TinyMCE has (probably) used something like HTMLPurifier to keep the nasties out of the HTML you're intentionally allowing the user to submit.
For example, HTMLPurifier will take a string of (potentially malformed) HTML and strip out disallowed elements and attributes, try to fix broken HTML, and in some cases convert things like <i> to <em>.
Does anything equivalent exist for Rails (3)? What's the generally accepted way to sanitize input from rich text editors in Rails so that you can output the unescaped HTML onto a web page and know that stuff like <style> and <script> tags have been taken out of it and it's not going to break your page (or steal your cookies!)?
EDIT | Anybody used Sanitize? Any other options with pro's & con's?
You can use the sanitize method.
sanitize(html)
There is also a Sanitize gem.
Sanitize.clean(html)
I tend to prefer the Sanitize gem because it can be used as a before_save filter in your models instead of having to use the sanitize method in each of your views.
I'd like to have a link generated with BlueCloth that opens in a new window. All I could find was the ordinary [Google](http://www.google.com/) syntax but nothing with a new window.
Ideas?

Here is a complete reference for markdown: http://daringfireball.net/projects/markdown/syntax
And since there is no mention of how to set the target attribute, I would believe it is not directly possible, but the reference also says:
For any markup that is not covered by
Markdown’s syntax, you simply use HTML
itself. There’s no need to preface it
or delimit it to indicate that you’re
switching from Markdown to HTML; you
just use the tags.
Source: http://daringfireball.net/projects/markdown/syntax#html
So I would suggest you have to use the html syntax for links like this
update
if you wrap the markdown generated content in a div with a specific id like this:
and you use jQuery, you can add the following javascript:
$('#some_id a').attr('target','_blank');
Or you can save the BlueCloth output in a variable before outputting.
markdown_generated_string.gsub!(/<a\s+/i,'<a target="_blank" ')
I am using FckEditor in Create.aspx page in asp.net mvc application.
Since I need to show rich text in web pages, I used ValidateInput(false) attribute top of action method in controller class.
And I used Html.Encode(Model.Message) in Details.aspx to protect user's attack.
But, I had result what I did not want as following :
<p> Hello </p>
I wanted following result not above :
Hello
How can I show the text what user input?
Thanks in advance
The short answer is that HTMLEncode is making your markup show like that. If you don't HTMLEncode, it will do what you want.
You need to think about whether or not you need full control of markup, who is entering the markup, and if an alternative like BBCode is an option.
If your users using the editor are all sure to be 'safe' users, then XSS isn't likely to be as much a concern. However, if you are using this on a comment field, then BBCode, or something like SO itself uses is more appropriate.
You wont be able to use a WYSIWYG editor and do HTMLEncode though... (without BBCode, or some other token system)
It seems the user entered "<p> Hello </p>" (due to pressing Enter?) into the edit control, and it is displaying correct in the HTML as you have done an Html.Encode. E.g. the paragrahs are not rendered, they are outputted as "<p>..</p>" as the string is HTML encoded into something like "<p> Hello <p>".
If you do not want tags, I would suggest searching the text string for tags (things with <...>) and removing them from the inputted text. Do this before HTML.Encode.
...or am I missing something?
You can use HttpServerUtility.HtmlEncode(String)
