Hi, Graham,
Here's my quick-and-dirty...

Bear in mind that the above is not valid XML. There must be one top-level
tag that encloses all other content. With that bit of nit-picky-ness firmly
in place... ;-) , the demo script below, %xml2obj.r
REBOL []
phlarp: parse-xml {
<data>
<HB>105</HB><WBC>7.1</WBC><PLATELETS>400</PLATELETs><ESR>100</ESR>
</data>
}
objblock: copy []
foreach item phlarp/3/1/3 [
if block? item [
append objblock reduce [to-set-word item/1 item/3/1]
]
]
objobj: make object! objblock
probe objobj
get in objobj 'HB
produces as output
>> do %xml2obj.r
make object! [
HB: "105"
WBC: "7.1"
PLATELETS: "400"
ESR: "100"
]
== "105"
Obviously a real application of this idea would traverse an entire
"multi-record" XML tree with something more intelligent than
phlarp/3/1/3
but that is "left as an exercise for the reader". Hope this helps!
