Hi,

I have file people.wsdl:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions
targetNamespace="http://localhost:8080/wsapp/services/PeopleService"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">
<wsdl:portType name="PeopleService">
<wsdl:operation name="add" parameterOrder="name sex age"/>
<wsdl:operation name="getList"/>
<wsdl:operation name="del" parameterOrder="id"/>
</wsdl:portType>
</wsdl:definitions>

I need to get all wsdl:portType and all wsdl:operation for every
wsdl:portType.

Code:

var doc =
document.implementation.createDocument("http://schemas.xmlsoap.org/wsdl/","wsdl",null);
doc.load("people.wsdl");
var definitions = doc.getElementsByTagName("definitions");
alert(definitions[0].getAttribute("targetNamespace"));
var portType = doc.getElementsByTagName("portType");
alert(portType[0].getAttribute("name"));
var operation = doc.getElementsByTagName("operation");
for(var i=0; i<portType.length; i++) {
alert(operation[i].getAttribute("name"));
}

On line 4 I got error:

Error: definitions[0] has no properties

What's wrong?

Can I use XPath expressions like this:

getElementsByTagName("/definitions/portType/operation[0]") ?

This is async, the rest of the code needs to go into the onload handler.
See http://www.mozilla.org/projects/xslt/js-interface.html for sample code.

Thanks

Where can I read about Document events? Has it error event? How can I
handle it?

Why this code don't show alert:

var doc = document.implementation.createDocument("","",null);
doc.addEventListener("load", onload, true);
doc.load("people.wsdl");
function onload() {
alert(doc);
}
