Hi,

Since Trac doesn't have a possibility to discuss such things before editing
the Webpage I'd like to post two other Variants here for discussion:
Simulate XMLSerializer globally and use it always - change the serialization
function on first call to distinguish between IE and others.
----
if (typeof XMLSerializer == 'function') {
XMLSerializer = function() {};
XMLSerializer.prototype.serializeToString = function(node) {
var fn = function(node) {return node.xml; };
if (this[0].xml !== undefined) {
fn = function(node) {
// TODO: Manually serialize DOM here, for browsers
// that support neither of two methods above.
};
}
XMLSerializer.prototype.serializeToString =
this.serializeToString = fn
return fn(node);
}
}
$.fn.toXML = function () {
var out = '';
if (this.length > 0) {
var xs = new XMLSerializer();
this.each(function() {
out += xs.serializeToString(this);
});
}
return out;
};
----
Change the toXML-function at first call
----
$.fn.toXML = function () {
var fn = function() {
var out = '';
this.each(function() { out += this.xml; });
return out;
};
if (typeof XMLSerializer == 'function') {
fn = function() {
var out = '';
var xs = new XMLSerializer();
this.each(function() {
out += xs.serializeToString(this);
});
return out;
};
} else if (this[0].xml === undefined) {
fn = function() {
var out = '';
// TODO: Manually serialize DOM here, for browsers
// that support neither of two methods above.
return out;
};
}
$.fn.toXML = fn;
return fn.apply(this,[]);
};
----
I admit, that the two suggestions might not be to easy to understand. I like
to play with functions as values :-)
At least the first one provides a more general solution by simulating
XMLSerializer and both of them are faster after the first call. That might be
a criterium if you work with large Datasets. If performance is imortant to
you, you might also consider to replace the calls to each() with for-loops.
