I have been trying to use OWSLib to chain my PyWPS Process requests but am finding it difficult as there is no examples of how this is achieved using OWSLib. I have been able to 'simulate' a chained request by sending requests in order and then using the output from the first as the input to the next. I have also tried embedding a request in another but have found that the library escapes the xml special characters, resulting in malformed xml. I also attempted to manually create an XML POST request but not sure how the embedding is achieved ie. what is the element called that identifies a chained or embedded request. So I would therefore like to know if anyone can point me in the right direction in terms of what the XML for a chained PyWPS request would look like.</div><div class=""><div class=""><br class=""></div><div class="">Thanks,</div><div class="">Suzana</div>-- <br class=""><div dir="ltr" class="gmail_signature" data-smartmail="gmail_signature"><div dir="ltr" class=""><div class=""><div dir="ltr" class=""><p style="font:7.5pt/normal arial,sans-serif;color:gray;text-transform:none;text-indent:0px;letter-spacing:normal;word-spacing:0px;white-space:normal;font-size-adjust:none;font-stretch:normal;background-color:rgb(255,255,255)" class=""><b class="">Dr Suzana Barreto<br class="">Software Analyst<br class="">Environment Systems</b><br class="">Tel: <a style="color:rgb(17,85,204)" href="tel:%2B44%20%280%29%201970%20626688" value="+441970626688" target="_blank" class="">+44 (0) 1970 626688</a><br class=""><a style="color:rgb(17,85,204)" href="http://www.envsys.co.uk/" target="_blank" class="">www.envsys.co.uk</a></p><p style="font:7.5pt/normal arial,sans-serif;color:gray;text-transform:none;text-indent:0px;letter-spacing:normal;word-spacing:0px;white-space:normal;font-size-adjust:none;font-stretch:normal;background-color:rgb(255,255,255)" class="">The information contained in this e-mail is intended only for the use of the person(s) to whom it is addressed and may contain confidential or privileged information.
