I have been handed a chunk of code from a developer that no longer works for us, and I am new to the regex game so to speak, so apologies if the answer seems simple.
the goal is to format an XML response into something that is readable and here is the code I have been presented with:
formatXml: function (xml) {
if (xml.indexOf('<') == -1) {
return xml;
}
//remove all white spaces
xml = xml.replace(/>s+|s+</g, function (m) {
return m.trim();
});
// remove extra variables
xml = xml.substring(xml.indexOf('<'), (xml.lastIndexOf('>') + 1));
var formatted = '';
var reg = /(>)(<)(/*)/g;
xml = xml.replace(reg, '$1rn$2$3');
var pad = 0;
jQuery.each(xml.split('rn'), function (index, node) {
var indent = 0;
if (node.match(/.+</w[^>]*>$/)) {
indent = 0;
} else if (node.match(/^</w/)) {
if (pad != 0) {
pad -= 1;
}
} else if (node.match(/^<w[^>]*[^/]>.*$/)) {
indent = 1;
} else {
indent = 0;
}
var padding = '';
for (var i = 0; i < pad; i++) {
padding += ' ';
}
formatted += padding + node + 'rn';
pad += indent;
});
return formatted;
}
The xml that is sent into this looks something like the following portion:

Why is it that the regex in formatXml doesn’t remove all of the escaped characters and the “” characters?
Also, what can I add in to this to be able to replace the u003d with =, u003c with <, and u003e with >?
