[xsl] how to rename attributes and restrict selection?

["bvhest.freeler.nl " <bvhest@xxxxxxxxxx>]

Hi all,
i am just starting with XML and transformations and encountered a problem i 
cannot solve myself. I hope you can help me. 

Thanks, Bart 

Apart from using xslt to transform the structure of my original XML 
document, i want to:
1) only transform those elements that are "part of a list" (i need to be 
able to specify/restrict the selection to the elements "B" with attributes 
"C" and "D" in the example below).
2) i want to rename the attribute of these selected elements (so attribute 
"C" will be renamed into "renamed_C", etc.) 

Is this possible?? 

p.s. the property-element is just copied into the new structure. 


Example:
========
Source XML:
<?xml version='1.0'?>
<A>
 <B name="C">
    <property name="property1">value1</property>
    <property name="property2">value2</property>
 </B>
 <B name="D">
    <property name="property3">value1</property>
    <property name="property4">value2</property>
 </B>
 <B name="E">
    <property name="property3">value1</property>
    <property name="property4">value2</property>
 </B>
</A> 

Target XML:
<?xml version='1.0'?>
<Z>
 <A>
    <B name="renamed_C">
    <property name="property1">value1</property>
    <property name="property2">value2</property>
    </B>
    <B name="renamed_D">
       <property name="property3">value1</property>
       <property name="property4">value2</property>
    </B>
 </A>
</Z>
