I know that the HTML entity for Man Walking as follows:
🚶
This renders fine in browser as:
🚶♂️
However, what is the HTML entity for a Woman Walking?
🚶♀️
Every time a user posts something containing <
or >
in a page in my web application, I get this exception thrown.
I don't want to go into the discussion about the smartness of throwing an exception or crashing an entire web application because somebody entered a character in a text box, but I am looking for an elegant way to handle this.
Trapping the exception and showing
An error has occurred please go back and re-type your entire form again, but this time please do not use <
doesn't seem professional enough to me.
Disabling post validation (validateRequest="false"
) will definitely avoid this error, but it will leave the page vulnerable to a number of attacks.
Ideally: When a post back occurs containing HTML restricted characters, that posted value in the Form collection will be automatically HTML encoded.So the .Text
property of my text-box will be something & lt; html & gt;
Is there a way I can do this from a handler?
I am trying to parse a string of HTML with ruby, this string contains multiple <pre></pre>
tags, I need to find and encode all <
and >
brackets in between each of these elements.
Example: string_1_pre = "<pre><h1>Welcome</h1></pre>"string_2_pre = "<pre><h1>Welcome</h1></pre><pre><h1>Goodbye</h1></pre>"def clean_pre_code(html_string) matched = html_string.match(/(?<=<pre>).*(?=<\/pre>)/) cleaned = matched.to_s.gsub(/[<]/, "<").gsub(/[>]/, ">") html_string.gsub(/(?<=<pre>).*(?=<\/pre>)/, cleaned)endclean_pre_code(string_1_pre) #=> "<pre><h1>Welcome</h1></pre>"clean_pre_code(string_2_pre) #=> "<pre><h1>Welcome</h1></pre><pre><h1>Goodbye</h1></pre>"
This works as long as html_string
contains only one <pre></pre>
element, but not if there are multiple.
I would be open to a solution that utilizes Nokogiri or similar, but couldn't figure how to make it do what I want.
Please let me know if you need any additional context.
Update:This is possible only with Nokogiri, see accepted answer.
As ScottGu says in his blog post «by default content emitted using a @ block is automatically HTML encoded to better protect against XSS attack scenarios».My question is: how can you output a non-HTML-encoded string?
For the sake of simplicity, pls stick to this simple case:
@{ var html = "<a href='#'>Click me</a>" // I want to emit the previous string as pure HTML code...}
Are they the same as XML, perhaps plus the space one (
)?
I've found some huge lists of HTML escape characters but I don't think they must be escaped. I want to know what needs to be escaped.
