utl.js

代码如下:

function createXmlTree(node, indent) {

if (node == null)
return "";
var str = "";

switch (node.nodeType) {
case 1: // Element
str += "

<" + node.nodeName + "";

var attrs = node.attributes;
for (var i = 0; i < attrs.length; i++)
str += createXmlAttribute(attrs[i]);

if (!node.hasChildNodes())
return str + "/>

";

str += ">
";

var cs = node.childNodes;
for (var i = 0; i < cs.length; i++)
str += createXmlTree(cs[i], indent + 3);

str += "</" + node.nodeName + ">

";
break;

case 9: // Document
var cs = node.childNodes;
for (var i = 0; i < cs.length; i++)
str += createXmlTree(cs[i], indent);
break;

case 3: // Text
if (!/^\s*$/.test(node.nodeValue))
str += "" + node.nodeValue + "
";
break;

case 7: // ProcessInstruction
str += "<?" + node.nodeName;

var attrs = node.attributes;
for (var i = 0; i < attrs.length; i++)
str += createXmlAttribute(attrs[i]);

str+= "?>
"
break;

case 4: // CDATA
str = "

<![CDATA[" +
node.nodeValue +
"]" + "]>

";
break;

case 8: // Comment
str = "

";
break;

case 10:
str = "

<!DOCTYPE " + node.name;
if (node.publicId) {
str += " PUBLIC \"" + node.publicId + "\"";
if (node.systemId)
str += " \"" + node.systemId + "\"";
}
else if (node.systemId) {
str += " SYSTEM \"" + node.systemId + "\"";
}
str += ">

";

// TODO: Handle custom DOCTYPE declarations (ELEMENT, ATTRIBUTE, ENTITY)

break;

default:
//alert(node.nodeType + "\n" + node.nodeValue);
inspect(node);
}

return str;
}

function inspect(obj) {
var str = "";
for (var k in obj)
str += "obj." + k + " = " + obj[k] + "\n";
window.alert(str);
}

function createXmlAttribute(a) {
return " " + a.nodeName + "=\"" + a.nodeValue + "\"";
}

代码如下:

Ajax test

rel=stylesheet>

onchange='XMLDoc1.url=this.value;document.getElementById("XMLDebug")[xss_clean]=""'>
value=xtree.xsl>xtree.xsl

代码如下:
