Reading and terminating stream in HttpClient 4

["droidin.net" <dr...@droidin.net>]

Hi,

Here's what I need to do
1. Read response as a stream 
2. Feed it into SAX-based HTML parser "on the fly"
3. When certain tag is detected - terminate the stream

In other words - I'm reading large documents from which I only need top 5%,
can I do it with HttpClient 4?

Thanks for your suggestions

Use the HttpEntity#getContent() method, which returns an  
java.io.InputStream, and pass that to your SAX-based HTML parser.

When you see the tag you need, terminate the request via invoking the  
HttpUriRequest#abort() method.
