Simple Xpath question; retrieve attributes for specific parent

[samsquared]

I have an xml file that looks like this:

<DocBuild name="ABC">
<BldArea name="Components" product="ABC" area="C">
<BldItem name="Item1" module="mod1" tier="A" buildtype="auto"/>
<BldItem name="Item2" module="mod2" tier="B" buildtype="auto"/>
</BldArea>
<BldArea name="Core" product="ABC" area="C">
<BldItem name="Item5" module="mod5" tier="A" buildtype="auto"/>
<BldItem name="Item6" module="mod6" tier="B" buildtype="auto"/>
</BldArea>
</DocBuild>

I want to retrieve the name and tier attributes for BldItem elements whose BldArea is "Components". To get both attributes I can use something like BldItem/@name|BldItem/@tier but how do I specify that I just want those under 'Components'? There will be only one BldArea that contains name="Components" in the actual XML file.

[jkmyoung]

BidArea[@name = 'Components']/BldItem/@name | BidArea[@name = 'Components']/BldItem/@tier

or depending on context perhaps:
(BldItem/@name|BldItem/@tier)[../../@name='Components']

Thank you - that did it! (I didn't try your second suggestion.)
