SOAP request fails

[tosbaha]

For the following XML document(SOAP service), XPath can't find the elements.

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
    <soapenv:Body>
        <ServiceResponse xmlns="http://sub.domain.com">
            <ServiceReturn>
                <a>US</a>
                <b>
                    <b>
                        <e>Herrod</e>
                        <f>molestie@necmetus.edu</f>
                        <g>Et Commodo LLC</g>
                        <i>07/14/2014</i>
                    </b>
                    <b>
                        <e>Armand</e>
                        <f>est@vitae.org</f>
                        <g>Vel Convallis In Consulting</g>
                        <i>04/18/2015</i>
                    </b>
                    <b>
                        <e>Bernard</e>
                        <f>nulla@blandit.net</f>
                        <g>Cursus Nunc Mauris PC</g>
                        <i>11/12/2015</i>
                    </b>
                    <b>
                        <e>Dante</e>
                        <f>lorem@acmi.org</f>
                        <g>Sit Amet Ltd</g>
                        <i>01/19/2016</i>
                    </b>
                </b>
                <c>0</c>
                <k>12345678</k>
            </ServiceReturn>
        </ServiceResponse>
    </soapenv:Body>
</soapenv:Envelope>

Here are the result of some functions

document.rootElement.firstChildWithTag("Body", inNamespace: "soapenv") //some
document.rootElement.firstChildWithTag("//soapenv:Body/ServiceResponse") //nil
document.rootElement.firstChildWithTag("//Body//b", inNamespace: "soapenv") //nil
document.firstChildWithXPath("//ServiceResponse") //nil
document.firstChildWithXPath("//ServiceReturn") //nil
document.firstChildWithXPath("//*/ServiceReturn/b/b") //nil
document.firstChildWithXPath("//ServiceReturn/b/b") //nil
document.firstChildWithXPath("//b/b") //nil

Another example

<?xml version="1.0" encoding="UTF-8"?>
<S:Envelope xmlns:S="http://schemas.xmlsoap.org/soap/envelope/">
   <S:Body>
      <ns2:OperationHistoryData xmlns:ns2="http://www.domain.org/operation" xmlns:ns3="http://www.domain.org/info" xmlns:ns5="http://www.domain.org/data">
         <ns2:historyRecord>
            <ns2:DestinationAddress>
               <ns2:Index>190000</ns2:Index>
               <ns2:Description>Info 1</ns2:Description>
            </ns2:DestinationAddress>
         </ns2:historyRecord>
      </ns2:OperationHistoryData>
   </S:Body>
</S:Envelope>

Whenever there is nested namespaces, ono can't parse it. I don't know maybe it is limitation of libxml. Only workaround I found is to strip name spaces and other attributes.

I have the same problem and have to go down the elements until I get to the element I want:

ONOXMLElement *dataElement = [[[[[[[[[document.rootElement.children firstObject] children] firstObject] children] firstObject] children] firstObject] children] firstObject];

Here are some details about the problem:

"The ‘gotcha’ moment with our response message is that the namespace “xmlns=http://ws.cdyne.com/WeatherWS/” does not have a prefix for the declaration. By not defining a prefix, it is defaulting to the default namespace or null namespace and we cannot use XPath expressions to reference the null namespace."

Hi @mattt,

What is the status of this issue? It seems like I'm experiencing it too.

Apologies for not responding sooner, everyone. I'm not very familiar with SOAP, but I'd like to make any necessary fixes for this in code and/or documentation. I'll add the example you provided, @tosbaha, as a failing test case in a branch and work to figure out a solution.

"The ‘gotcha’ moment with our response message is that the namespace “xmlns=http://ws.cdyne.com/WeatherWS/” does not have a prefix for the declaration. By not defining a prefix, it is defaulting to the default namespace or null namespace and we cannot use XPath expressions to reference the null namespace."

In the meantime, have you tried calling the definePrefix:forDefaultNamespace as a workaround?

[tosbaha]

Sorry but this issue was so old. I don't work on this anymore. I think I made it work by stripping the name spaces. Since I don't have the old code anymore, I can't comment whether your workaround works or not. Cheers.

I've tested this by calling definePrefix:forDefaultNamespace, however, XPath queries still returns nil
