Re: [httpclient] Parse response for NameValuePairs?

[John Burke]

Hello Adrian,
I'm using httpclient to automate the process of using an online
reservation system.  This is the first project I have used it for
so I'm am grasping at some new concepts.  At one point in the
script, I execute a get method and I get a few kilobytes from the
server.  Buried in there is a :  <INPUT TYPE="radio" NAME="xxx"
VALUE="yyy"> tag.  There may be more than one, but I have to respond
with my choice in the next POST method if I want to continue the
reservation process.  I thought the getmethod class might have a
method that culls the server response for these gems and returns
a set of NameValuePair class instances.  It would make building
the post method a little easier for the newbies, but I may just be lazy.
How would you handle this?
Thanks for your response.

Hi John,
I take it you wanted to get the name and value of all the headers 
returned
in the response.  You can use the getResponseHeaders() method in any
HttpMethod which will return an array of Headers.

Each header though can contain multiple values so you'd have to 
iterate over
the headers and the over the values for each header.  Something like:

Header[] headers = method.getResponseHeaders();
for (int i = 0; i < headers.length; i++) {
        String headerName = headers[i].getName();
        HeaderElement[] elements = headers[i].getValues();
        for (int j = 0; j < elements.length; j++) {
                HeaderElement el = elements[j];
                // At this stage you have the header and it's value.
                // See below for information on some "funky" headers
        }
}
Some headers can contain multiple values within the header value, in
particular cookie headers do this.  You can repeat the pattern above to
iterate over the parameters of the HeaderElement to get a name value 
pair of
each element if that's what you want.  It really depends what level of
detail you need to go to.

Why were you wanting to do this?

Subject: [httpclient] Parse response for NameValuePairs?
Hi, I've looked through the API docs but didn't find what I wanted.
I'm wondering if there is a method that will find and return all
NameValuePairs
from a given response?  If not can anyone please suggest a few lines
of code?  Thanks.
