wsdl
You can try using one of their tools: http://www.ws-i.org/deliverables/workinggroup.aspx?wg=testingtools
These will check both WSDL validity and Basic Profile 1.1 compliance.
If you're using Eclipse, just have your WSDL in a .wsdl file, eclipse will validate it automatically.
From the Doc
The WSDL validator handles validation according to the 4 step process defined above. Steps 1 and 2 are both delegated to Apache Xerces (and XML parser). Step 3 is handled by the WSDL validator and any extension namespace validators (more on extensions below). Step 4 is handled by any declared custom validators (more on this below as well). Each step must pass in order for the next step to run.
You can try out wsdl validator http://docs.wso2.org/wiki/display/ESB451/WSDL+Validator
If you would to validate WSDL programatically then you use WSDL Validator out of eclipse. http://wiki.eclipse.org/Using_the_WSDL_Validator_Outside_of_Eclipse should help or try this tool Graphical WSDL 1.1/2.0 editor.
