Remove unwanted whitespaces between tags in XML (Javascript)

Question

I receive an XML formatted as follows.

<rec>
      <id> servicedescription </id>
      <name> Description Value </name>
      <type> textbox </type>
</rec>

But this won't work since my system doesn't accept the spaces present between the tags. I require something as follows

<rec>
      <id>servicedescription</id>
      <name>Description Value</name>
      <type>textbox</type>
</rec>

Please help me out in Javascript. Thanks a lot

PS : Extremely sorry if this question has been asked before. I searched quite a lot but didn't get the info.

I receive a DOM object which has the XML. I serialize it into String format, convert it into JSON and process it. — StackAddict

The following code should do the work (http://jsfiddle.net/b8FBn/):

var str = "<rec> <id> servicedescription </id> <name> Description Value </name> <type> textbox </type></rec>";
str = str.replace(/>\s*/g, '>');  // Replace "> " with ">"
str = str.replace(/\s*</g, '<');  // Replace "< " with "<"

alert(str);

This won't remove the redundant white space inside xml tags (between the attributes), but it mostly does the job, especially in case you don't have much of them. +1 from me
