function XMLWriter()
{
this.XML=[];
this.Nodes=[];
this.State="";
this.FormatXML = function(Str)
{
if (Str)
return Str.replace(/&/g, "&").replace(/\"/g, """).replace(/, "/g, ">");
return ""
}
this.BeginNode = function(Name)
{
if (!Name) return;
if (this.State=="beg") this.XML.push(">");
this.State="beg";
this.Nodes.push(Name);
this.XML.push(" }
this.EndNode = function()
{
if (this.State=="beg")
{
this.XML.push("/>");
this.Nodes.pop();
}
else if (this.Nodes.length>0)
this.XML.push(""+this.Nodes.pop()+">");
this.State="";
}
this.Attrib = function(Name, Value)
{
if (this.State!="beg" || !Name) return;
this.XML.push(" "+Name+"=\""+this.FormatXML(Value)+"\"");
}
this.WriteString = function(Value)
{
if (this.State=="beg") this.XML.push(">");
this.XML.push(this.FormatXML(Value));
this.State="";
}
this.Node = function(Name, Value)
{
if (!Name) return;
if (this.State=="beg") this.XML.push(">");
this.XML.push((Value=="" || !Value)?"":""+this.FormatXML(Value)+""+Name+">");
this.State="";
}
this.Close = function()
{
while (this.Nodes.length>0)
this.EndNode();
this.State="closed";
}
this.ToString = function(){return this.XML.join("");}
}
XMLWriter 有以下几个方法:
BeginNode (Name)
EndNode ()
Attrib (Name, Value)
WriteString (Value)
Node (Name, Value)
Close ()
ToString ()
BeginNode 输出一个标签：
XML.BeginNode(“Foo”);
XML.BeginNode(“Foo”);
XML.Attrib(“Bar”, “Some Value”);
WriteString 方法：
XML.Node(“MyNode”, “My Value”);
//Produces:
XML.BeginNode(“Foo”);
XML.WriteString(“Hello World”);
XML.EndNode();
//Produces
Node 方法：
XML.EndNode();
//Produces:
eg:
function WriteTest()
{
try
{
var XML=new XMLWriter();
XML.BeginNode("Example");
XML.Attrib("SomeAttribute", "And Some Value");
XML.Attrib("AnotherAttrib", "...");
XML.WriteString("This is an example of the JS XML WriteString method.");
XML.Node("Name", "Value");
XML.BeginNode("SubNode");
XML.BeginNode("SubNode2");
XML.EndNode();
XML.BeginNode("SubNode3");
XML.WriteString("Blah blah.");
XML.EndNode();
XML.Close(); // Takes care of unended tags.
// The replace in the following line are only for making the XML look prettier in the textarea.
document.getElementById("ExampleOutput").value=XML.ToString().replace(/,"\n }
catch(Err)
{
alert("Error: " + Err.description);
}
return false;
}
生成的xml为：
