Whitespace in input control from valid XML

In recent versions of formsplayer, XML that used to behave properly is no longer doing so.
For example, XML containing the following 'A' element would historically be displayed in an input control as an empty string.
<Sample>
<A>
</A>
</Sample>
Now, the input control displays several spaces.

One way around this is to rewrite the XML as follows:
<Sample>
<A/>
</Sample>

However, when this XML is sumbitted (using Put method), the format of the XML is changed to that described in example 1
When the XML is redisplayed we again have the whitespace issue described at the outset.
