How can I create lists with Parent items of child attributes using E4X?

[Stonefly]

I'm having trouble getting the results I want using E4X to dig into my XML document. For exampleWhat I want to do, using the XML below, is find all of the d_locations that have the d_type SW, and then create a list of all the SW d_types that includes the code and the hfloor number - which is a level above the d_type.So to illustrate the example, I want to output a list like this:TYPE: SWFloor 18: SW18.10NFloor 15: SW15.W2Floor 15: LB12Floor 15: LB17Floor S2: SWS2.3How can I do that using E4X? Thanks so much!Mattynabib\[code\]<?xml version="1.0" encoding="UTF-8"?><bldg><hfloor number="18"><d_location d_code="SW18.10N" d_type="SW" description="Ferbludgit thingamabob"> <d_image>3e_pic1</d_image> <d_image>3e_pic2</d_image> <d_image>3e_pic3</d_image> <d_image>3e_pic4</d_image> <d_image>3e_pic5</d_image> <d_video>3e_vid_1</d_video> <d_video>3e_vid_2</d_video> <d_video></d_video></d_location></hfloor><hfloor number="15"><d_location d_code="W1" d_type="PSW" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="SW15.W2" d_type="SW" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="W3" d_type="LB" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location> <d_location d_code="LB12" d_type="SW" description="Screwed up whosamadingy"> <d_image>media/lb15_12/LB-12 LOOKING NORTH.png</d_image> <d_image>media/lb15_12/LB-12 LOOKING SOUTH.png</d_image> <d_image>media/lb15_12/Pages from Level_15_Link_Beam_12.png</d_image> <d_image>media/lb15_12/Pages from Level_15_Link_Beam_12-2.png</d_image> <d_image>media/lb15_12/Post Demo from CITC018306365-2.png</d_image> <d_image>media/lb15_12/Rebuilt from CITC018306365.png</d_image> <d_image>media/lb15_12/WEI LB 12 level 15.png</d_image> <d_video>Video 1</d_video> <d_video>Video 2</d_video> <d_video>Video 3</d_video></d_location><d_location d_code="LB17" d_type="SW" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="LB8" d_type="EB" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="W14" d_type="CB" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location></hfloor><hfloor number="S2"><d_location d_code="W3" d_type="LB" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="SWS2.3" d_type="SW" description="Whacked flogatron"> <d_image>media/sw_s2_3/CITC000155966.png</d_image> <d_image>media/sw_s2_3/CITC000155983.png</d_image> <d_image>media/sw_s2_3/CITC000155996.png</d_image> <d_image>media/sw_s2_3/CITC000156003.png</d_image> <d_image>media/sw_s2_3/Screen shot 2012-04-19 at 5.54.42 PM.png</d_image> <d_image>media/sw_s2_3/WEI SWS2.3.png</d_image> <d_video>lbs.6e vid</d_video> <d_video></d_video> <d_video></d_video></d_location><d_location d_code="LB17" d_type="ES" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location><d_location d_code="LB8" d_type="SW" description="Broken fetzer valve"> <d_image>3s_pic1</d_image></d_location></hfloor></bldg>\[/code\]
