Re: [Simple-support] ElementMap question

[Micah J. <mi...@af...>]

Thanks for responding!  So I stumbled on a solution nearly the same as  
what you suggested.  In my below example, I separated out the value of  
the text into a value tag just as you suggested, but kept everything  
else the same.  And the code suddenly started working (for reasons I  
don't understand).  I didn't have to create a list to put values into  
a map.  This was my new XML, code is still the same:

<foo level="0">
<value attr1="abc">value1</value>
</foo>
<foo level="1">
<value attr2="xyz">value2</value>
</foo>
<foo level="3">
<value attr1="123">value3</value>
</foo>

What is confusing to me on why this is working is I didn't create an  
annotation to look for the tag "value".  Does ElementMap do some  
shortcutting to look for "value" tags for you?
