HttpWebResponse.GetResponseStream converts &lt; instead of < etc.

I am using an HttpWebRequest to retrieve XML data from a web service.

My content type is:
request.ContentType = "text/xml; charset=utf-8";

The problem is, when I retrieve the text, everything inside the Envelope, the response, is converted. So <> are &lt; and &gt;, etc..

How do I retrieve the data, and retain the less than / greater than symbols for valid XML?

thanks!

Well, yeah. But I thought there should be a way of retrieving the data WITHOUT it converting in the first place.

Is that not possible? Or do you not know?

thanks.

since < and > are already in use by HTML so whenever the service that you are using is returning the xml response in http, it is encoding these characters and returning back.

However if the service that you are calling is a RESTFUL Service it will not return any html response, so you will get your xml already decoded.

So a lot depends a lot on what kind of web service you are working with, is it asmx or wcf service. Is this service in your control???

Hi,

use the below code to get the correct XML response.

after getting response from the request, use the streamreader to read the xml values.
this will give you the exact xml data.
string httpResponse = "";
string requestUrl = "http://www.domain.com/Service.asmx/Method1?Param1=string&Param2=string&Param3=string";

HttpWebRequest request = (HttpWebRequest)WebRequest.Create(requestUrl);

WebResponse response = null;
StreamReader reader = null;
try
{
	response = request.GetResponse();
}
catch (WebException ex)
{
	response = ex.Response;
}

reader = new StreamReader(response.GetResponseStream());
httpResponse = reader.ReadToEnd();

TextBox2.Text = httpResponse;

Open in new window

Try this.

Hope this will work for you.

srosebabu,

That produces the same thing.. the < >'s are converted:

    &lt;/client&gt;
    &lt;order_dataset&gt;

Decoding is not helping, because it also decodes values within the elements. Then I get an error:

>>Data at the root level is invalid. Line 1, position 1

Because the text was replaced with an open carat:

<class>GVWR<26001</class>

any open carets and other XML keys have to be sent as <CData></CData>

strange... but, my sample code produces XML structure correctly.

update requestUrl  with the below sample url and test once.
string requestUrl = "http://constantine.lirmm.fr:8080/CentileParSaisieWS_GFV2/CentileWSService?wsdl";

//string requestUrl = "http://wsf.cdyne.com/WeatherWS/Weather.asmx/GetWeatherInformation?";

Open in new window

I found the solution.

I had to use HtmlDecode to decode the commands without decoding the element text.

Thanks all!
