After successfully load data, one webKit, need to extract token from it.
Which is embeded in HTML.
Is it an javascript injection -> for evaluate value from HTML?

I'm working on a URL preview widget, so I'd like to extract the meta tags from the HTML of a given URL.
However, the problem is that websites like Twitter don't return the entire HTML when they detect there's no JavaScript engine enabled (i.e. doing a GET request from the http package).
So, I'd like to know if there's any workaround for these cases, for example, using some kind of headless browser to get the entire HTML.
Thanks!
I have a PDF which has a submit button which will submit the PDF fields as an html form to my web API. The submit part works, however it is sending the request payload in a format I have never seen before
Also the request doesn't show the content-type being sent. I supposed it was being sent as application/octet-stream so I added this custom MediaTypeFormatter I found and it still didn't work.
I am filling the PDF fields using iTextSharp and the sending it to the client. The client creates a BLOB URL to display it in an iframe. I noticed that the problem is due to this, because when opening the PDF by itself and filling the data manually and then submitting it works fine, so the problem has to be either when I fill the form fields or when I create the BLOB URL in the client.
That's an Adobe format called FDF (Forms Data Format) but that's just one option for the submit format. You can also submit the data as the equivalent of an HTML GET using the settings shown in the images below.
If your API can accept data from HTML forms, it should work from Acrobat as well.
Hi friends I am developing an application in Blackbery10 to parse the xml data in an html page. That the html is loaded in a webview and the html source contains some xml tags. Please help me to get the html source code of web view in blackberry10.
On the Webview you can use a function evaluateJavaScript (const QString &script, bb::cascades::JavaScriptWorld::Typeworld world) to execute a javascript function to get the text or xml you need. You should be able to evaluate the following expression:
return document.documentElement.innerHTML;
You can then retrieve the evaluated expression from the signal javaScriptResult
You cannot access the HTML of a WebView that was loaded from network
If you want an application highly based on HTML, you can have a look at WebWorks. If you still require the native framework, you have to request the content yourself, parse it, and then inject it into the webview.
I'm using Xcode to build an app to monitor a web page to see if the HTML changes. I want to extract a website's HTML source to compare it to the same website's HTML source at a later time to see if the website has changed. I can't find anything that would allow me to do this.
If it's not possible to extract the HTML of a site, I need some way to check for changes in the website.
Use NSURLConnection to retrieve the page as an NSData instance, and save it in an ivar (for example). Then retrieve it again into another NSData instance and compare the two instances using NSData isEqualToData:.
Let's say that I have a link to a webpage that contains some text. What's the easiest way to grab this text to process?
Thanks.
Long story short, I don't think it's possible to make a request from the client js to grab the text from a url with a different domain.
It is possible to make requests to load json. This link describes how.
Basically, the steps are:
Embed a tag in the GWT page
after GWT page is initialized, update
the script tag's src to load remote
url
remote url returns some json data
padded inside a callback javascript
function such as:
callback({blah:foo})
So, you're only option may be writing a method on the server side that loads the url, gets the text. You could then call this method from gwt client using normal rpc technique.
Assuming same origin: use the "RequestBuilder" class.
If you are trying to grab a webpage from a different origin, then it obviously won't work.
