I have a generic XML file:

<nodes>
<node1 att1='abc' att2='xyz'>
<ele1> Hello </ele1>
<ele2> Hi </ele2>
...
</node1>
....
</nodes>

The tag and attribute names above can be anything. I need a generic method to
strip off the XML markups and display the contents as:

node1@att1: abc
node1@att2: xyz
node1.ele1: Hello
node1.ele2: Hi
....

How can E4X do this?

e4x is for manipulating/navigating your xml. But you can use it inside a
for/each loop to look at your xml nodes and extract the strings without the xml
tags using toString().

Search the help docs for "XML type conversion" and see the toString() method
in action.
