Manipulating XML file data using JavaScript. Actually, just the last two lines of the function are enough to load the XML file. The previous two lines are written to ensure that the JavaScript functions that we may use later to manipulate the XML file data, does not perform any function on an uninitialized object.
var node = document. createElement("Item"); This will create HTML nodes instead of XML nodes and will result in a node with lower-case tag names. XML tag names are case-sensitive in contrast to HTML tag names.
Converting to XML and Writing to FIle readFile("test. xml", "utf-8", function(err, data) { if (err) console. log(err); // we log out the readFile results console. log(data); // we then pass the data to our method here parseString(data, function(err, result) { if (err) console.
Change the Value of an Attribute In the DOM, attributes are nodes. Unlike element nodes, attribute nodes have text values. The way to change the value of an attribute, is to change its text value. This can be done using the setAttribute() method or setting the nodeValue property of the attribute node.
I've found Ariel Flesler's XMLWriter constructor function to be a good start for creating XML from scratch, take a look at this
http://flesler.blogspot.com/2008/03/xmlwriter-for-javascript.html
Example
function test(){
var v = new XMLWriter();
v.writeStartDocument(true);
v.writeElementString('test','Hello World');
v.writeAttributeString('foo','bar');
v.writeEndDocument();
console.log( v.flush() );
}
Result
<?xml version="1.0" encoding="ISO-8859-1" standalone="true" ?>
<test foo="bar">Hello World</test>
One caveat to keep in mind is that it doesn't escape strings.
