Hey guys:

I have two variables defined. 

The first ($rules) looks something like:

<rule state="somestate1"> 
	<attrib name="attributename1"> ...</attrib>
	<attrib name="attributename2"> ...</attrib>
	<attrib name="attributename3"> ...</attrib>
</rule> 
<rule> 
	<attrib name="attributename1"> ...</attrib>
	<attrib name="attributename2"> ...</attrib>
	<attrib name="attributename3"> ...</attrib>
</rule> 
...


The second ($attribs) looks like:

<attrib name="attributename1" state="somestate1"> ...</attrib>
<attrib name="attributename2"> ...</attrib>
<attrib name="attributename3" state="somestate1"> ...</attrib>
...

Now what is all the all the attrib nodes from $rules whose name AND parents
state attribute are not present together in $attribs. Given the example
above, 
I want to select:
<rule state="somestate1"> 
	<attrib name="attributename1"> ...</attrib> <!-- Not this -->
	<attrib name="attributename2"> ...</attrib> <!-- This -->
	<attrib name="attributename3"> ...</attrib> <!-- Not this -->
</rule> 
<rule> 
	<attrib name="attributename1"> ...</attrib> <!-- This -->
	<attrib name="attributename2"> ...</attrib> <!-- Not this -->
	<attrib name="attributename3"> ...</attrib> <!-- This -->
</rule> 

Any ideas?
