Bio::DB::ESoap::WSDL(3) User Contributed Perl Documentation Bio::DB::ESoap::WSDL(3)

Bio::DB::ESoap::WSDL - WSDL parsing for Entrez SOAP EUtilities

Used by Bio::DB::ESoap

 # url
 $wsdl = Bio::DB::ESoap::WSDL->new(
    -url => "http://www.ncbi.nlm.nih.gov/entrez/eutils/soap/v2.0/eutils.wsdl"
  );
 # local copy
 $wsdl = Bio::DB::ESoap::WSDL->new(
    -wsdl => "local/eutils.wsdl"
  );

  %opns = %{ $wsdl->operations };

This module is a lightweight parser and container for WSDL XML files associated with the NCBI EUtilities SOAP server. XML facilities are provided by XML::Twig.

The following accessors provide names and structures useful for creating SOAP messages using SOAP::Lite (e.g.):

 service()    : the URL of the SOAP service
 operations() : hashref of the form {.., $operation_name => $soapAction, ...}
 request_parameters($operation) : 
    request field names and namelists as an array of hashes
 result_parameters($operation)  : 
    result field names and namelists as an array of hashes

The following accessors provide XML::Twig::Elt objects pointing at key locations in the WSDL:

 root            : the root of the WSDL docment
 _types_elt      : the <types> element
 _portType_elt   : the <portType> element
 _binding_elt    : the <binding> element
 _service_elt    : the <service> element
 _message_elts   : an array of all top-level <message> elements
 _operation_elts : an array of all <operation> elements contained in <binding>

Parsing occurs lazily (on first read, not on construction); all information is cached. To clear the cache and force re-parsing, run

 $wsdl->clear_cache;

The globals $NCBI_BASEURL, $NCBI_ADAPTOR, and %WSDL are exported.

 $NCBI_ADAPTOR : the soap service cgi

To construct a URL for a WSDL:

 $wsdl_eutils = $NCBI_BASEURL.$WSDL{'eutils'}
 $wsdl_efetch_omim = $NCBI_BASEURL.$WSDL{'f_omim'}
 # etc.

User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to the Bioperl mailing list. Your participation is much appreciated.

Please direct usage questions or support issues to the mailing list:

rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
