bubles_88 has asked for the wisdom of the Perl Monks concerning the following question:


Hi all,

I would like to develop a Perl Web CLient consuming Web Service made in Java (apache CFX).

THe Web Server produces WSDL in localhost.

I have two questions:
1. Are there ways other than SOAP that I can use to develop this Web Client?
2. I have tried using SOAP::Lite.
The Web Service (WSDL) has operation called Hello which accept input(input:Hello) and output the input(output:HelloResponse).

Here is my Perl code:

Expected: Input: Jimmy Output: Jimmy 
$svc = SOAP::Lite 
-> service('http://localhost:8000/Hello.wsdl') 
-> proxy('http://localhost:8000/Hello') 
-> on_action(sub {sprintf '%s/%s', @_}); 

$resp = $svc->Hello("Jimmy");

However, this code will produce empty result.
Executing "print $resp" produces empty result.

I have tried using SOAP::Data as below: 
<readmore title ="See the code">
$resp = $svc->call(SOAP::Data->name('Hello') 
->attr ({'xmlns'=>'sth'}) 
=> SOAP::Data->name('')->value("Jimmy"));

[download]


But this results in extra tags
<Hello xmlns="sth"><c-gensym3>Jimmy</c-gensym3></Hello>
which again resulted in empty final result: 
<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:xsi=htt
+p://www.w3.org/1999/XMLSchema-instance xmlns:SOAP-ENC=http://schemas.
+xmlsoap.org/soap/encoding/ xmlns:SOAP-ENV="http://schemas.xmlsoap.org

+V:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV
+:Body><Hello xmlns="sth"><c-gensym3>Jimmy</c-gensym3></Hello></SOAP-E
+NV:Body></SOAP-ENV:Envelope>

What i would like to have is:
<Hello xmlns="sth">Jimmy</Hello> 
<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:xsi=htt
+p://www.w3.org/1999/XMLSchema-instance xmlns:SOAP-ENC=http://schemas.

+V:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"><SOAP-ENV
+:Body><Hello xmlns="sth">Jimmy</Hello></SOAP-ENV:Body></SOAP-ENV:Enve
+lope>

Do you know how to remove the tags <c-gensym3> entirely?

Could you please help me in solving this issue?

Thank you very much

    How about a regex? Something like this: 
    $resp =~ s/<\/*c-gensym3>//gxms

    NB that this is very much untested, though.

      Hi. Thanks for the response.
      I am not sure where can i modify the xml code as it is resulted from error message.
      I have also tried to go to the website.
      If I use the "/", it will add another nested element.
      What I want is:
