nsdata to nsstring to nsdata

I am calling the web services. The web service returns data in xml format. Now the problem is the xml data is not being received in proper format. In place of "<", ">" it returns in html form.

So I assigned the xmldata to a NsMutableString and replaced the escape characters so that the format of xml data is proper. Then I reassigned the NSMutableString to NSData so that I can parse the tags. but the problem is the xmlparser stops right where the xml data is, where I replaced the tags. It doesn't go further. What is going on?

This is the xml response from web service that I called.

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:GetCustomerInfoResponse xmlns:ns1="http://aa.somewebservice.com/phpwebservice">
<return xsi:type="xsd:string">
    &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;&lt;customer&gt;&lt;id&gt;1&lt;/id&gt;&lt;customername&gt;Hitesh&lt;/customername&gt;&lt;phonenumber&gt;98989898&lt;/phonenumber&gt;&lt;/customer&gt;
</return>
</ns1:GetCustomerInfoResponse>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

And this is after I replaced the tags.

<?xml version="1.0" encoding="ISO-8859-1"?><SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/">
<SOAP-ENV:Body>
<ns1:GetCustomerInfoResponse xmlns:ns1="http://aa.somewebservice.com/phpwebservice">
<return xsi:type="xsd:string">
<?xml version="1.0" encoding="utf-8"?> 
 <customer><id>1</id><customername>Hitesh</customername><phonenumber>98989898</phonenumber></customer>
</return>
</ns1:GetCustomerInfoResponse>
</SOAP-ENV:Body></SOAP-ENV:Envelope>

Now the problem is while parsing the xml data, the parser only goes up to return tag. And then it is stuck there.

What parser do you use? On the iPhone you can use different parsers (eg: TouchXML or TinyXML), try to use they...

Also I think you would remove <?xml version="1.0" encoding="utf-8"?> from 'return' tag or replace it with another tag. Then when needed make the inverse transformation.
