I have a few strings and I would like to insert some line breaks into them at certain points.

I figured out a few of the logistics but as a whole I can't seem to crack this problem, probably because I have limited experience with regex.

Basically I have a long string of XML tags that is all on one line. I want to add line breaks at certain points to get the data more formatted and looking nice. I am using CodeMirror to display this data on a webpage but for some reason its all on line #1.

So I need to go from something like this:

<Sample><Name></Name><PhoneNumber><AreaCode></AreaCode><Number></Number></PhoneNumber></Sample>

To something like this:

<Sample>
  <Name></Name>
  <PhoneNumber>
    <AreaCode></AreaCode>
    <Number></Number>
  </PhoneNumber>
</Sample>

CodeMirror will take care of the rest of the formatting all I need to do is insert the line breaks in the right spot using regex or a loop of some sort. The Tags will or can change so I am guessing regex has to be used.

I have had success inserting line breaks with \n and &#xD but can't seem to get regex to detect the proper locations.

Any help would be greatly appreciated. Thanks.

UPDATE I overlooked this but the brackets are in fact being sent as < and >

So example tag would look like:

&lt;PhoneNumber&gt;

or

&lt;/PhoneNumber&gt;

So basically need to insert a \n after every &gt; that is a closing tag or a beginning tag that contains children tags.
