第一个ws.js，摘要代码如下：
var XML = {
createDocumentQName : function(qname) {
return XML.createDocument(qname.namespace,qname.value_of());
},
createDocument : function(namespace,nodename) {
return Try.these(
function() {
var doc = new ActiveXObject('Msxml2.XMLDOM');
var root = XML.createElementNS(doc, nodename, namespace);
doc.documentElement = root;
return doc;
},
function() {
var doc = new ActiveXObject('Microsoft.XMLDOM')
var root = XML.createElementNS(doc, nodename, namespace);
doc.documentElement = root;
return doc;
},
function() {
return document.implementation.createDocument(
namespace,
nodename,
null)
}
) || false;
},
createElementNS : function(document,nodename,namespace) {
var el = Try.these(
function() {
var el = null;
if (namespace) {
el = document.createNode(1,nodename,namespace);
} else {
el = document.createNode(1,nodename,"");
}
return el;
},
function() {
var el = null;
if (namespace) {
el = document.createElementNS(namespace,nodename);
} else {

}
return el;
}
) || false;
return el;
},
createElementQName : function(document,qname) {
return XML.createElementNS(document,qname.value_of(),qname.namespace);
},

var attr = Try.these(
function() { return document.createNode(2,nodename,namespace)},
