I'm consuming an API that returns encoded HTML entities on the response (I don't have access to the code).
This response contains text that will be later used on the HTML, such as inside
<p>, <h1> ...
I would like to know the best way to decode all the HTML entities on the document.
All the solutions I found tell me to decode each API response. But it isn't scalable on my case.
Btw, I'm using React.

I make use of an API that consists of a JSON with prefetched data from a CMS. The partial JSON looks like this:
"content": "<p><em>We're looking for a pro-active, analytical, commercially minded and ambitious deal-closer who loves to work - and play - hard to join our Company.
I then pass this data to a child component and then render it by using v-html. I expected this to output the HTML tags with styling and semantics. However, it renders the HTML tags as plain text:
<p><em/>We're looking for a pro-active, analytical, commercially minded and ambitious deal-closer who loves to work - and play - hard to join our Company.
Does anyone know what I am doing wrong? Should I have parsed the JSON? Should I have decoded the raw JSON to HTML tags first?
Nothing to do with JSON; everything to do with your web service unhelpfully giving you unparsed HTML.
You're going to have to decode these HTML entities yourself.
One common trick is to feed the unparsed HTML to an off-DOM element, then read it back via textContent, which will give you the parsed version.
let p = document.createElement('p');
p.innerHTML ='<p>'
console.log(p.textContent); //"<p>"
My query is that I want to convert html to json with C#. Is there any way to do it. I searched a lot and found articles related to using Javascript Serializer and Newtonsoft to serialize the html string to json. But these serializers do nothing except adding a opening and closing curly braces around the html string. I don't want that. I want to convert whole html to json so that I can get relevant information from the html using C# objects instead of parsing html with regular exressions. Html can be any valid html from any website available on the internet. I am getting the html using http request & response objects using C#.
Please don't suggest using html agility pack because that will also do the same thing that Serialization does.
If anybody have any idea how to do this with C# then please share your ideas.
I will tell why your question can cause confusion.
Consider example of html:
<html>
<body>
<p> example of paragraph </p>
</body>
</html>
Example of json:
{"employees":[
{"firstName":"John", "lastName":"Doe"},
{"firstName":"Anna", "lastName":"Smith"},
{"firstName":"Peter", "lastName":"Jones"}
]}
json is something, on which html is generated or initial fundament. So when you say you want to convert html to json it's really confusing, because it is impossible to figure out according to which rules you want to make this conversion. Or which tags from html should be ignored/added while creating json.
There is a javascript example of the solution here: Map HTML to JSON
DOM Parsers are pretty similar so you can try implementing it in C#. (I'd be interested in such implementation as well :D )
So I am fairly new to working with iOS applications and I am currently working on an application which pulls data from a website using NSURLSessionDataTask, parses the JSON response (HTML), and then populates a view with data from the response.
Currently, I am stuck trying to find a solution to correctly parsing my current HTML string (of type __NSCFString/NSString) from the JSON response, and putting the text into one or more UITextViews and images into one or more UIImageViews within the main ViewController.
It has previously been suggested to simply use a UIWebView to display everything or to use an outside library to do some of the converting, however I am curious if there are any methods by which I could parse the HTML and extract all relevant text or images and throw them into an array for later use. I would very much prefer to keep all of this native and not use outside libraries unless absolutely necessary.
I have also seen some use of the NSAttributedString class for parsing HTML from a JSON response, but am unsure if this is even relevant to what I am trying to do here. Any help/suggestions/thoughts are appreciated!
You can use the native NSXMLParser class. Checkout the documentation here.
Within your custom parsing class. You can generate NSAttributedString and store into array based on custom logic. This should help.
Classic problem. Want to see html rendered but I'm seeing text in the browser. Whether I tell handlebars js to decode it or not in template ( three curly braces vs two - {{{myHtmlData}}} vs {{myHtmlData}} ) doesn't get me there. Something about the JSON being returned via the model.fetch() has this html data wrapped up in such a way that it is resistant to the notion of displaying as HTML. It's always considered a string whether encoded or decoded so it always displays as text.
Is this just something backbone isn't meant to do?
The technologies involved here are:
backbone.marionette
handlebars.js
.NET Web API
Your data is being escaped automatically. It's a good thing, but since you're sure the data is a safe HTML. Use {{{}}} as in this other question Insert html in a handlebar template without escaping .
I need to be able to parse HTML snippets in an event-driven way. For example, if the parser finds a HTML tag, it should notify me and pass the HTML tag, value, attributes etc. to a delegate. I cannot use NSXMLParser because I have messy HTML. Is there a useful library for that?
What I want to do is parse the HTML and create a NSAttributedArray and display it in a UITextView.
YES you can parse HTML content of file.
If you want to get specific value from HTML content you need to Parce HTML content by using Hpple. Also This is documentation with exmple that are is for parse HTML. Another way is rexeg but it is more complicated so this is best way in your case.
