Given
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE idx [
<!ELEMENT idx (ent+)>
<!ELEMENT ent (item, pge+)>
<!ELEMENT item (#PCDATA)>
<!ELEMENT pge (#PCDATA)>
<!ATTLIST pge key (t|f) 'f'>
]>
<idx>
<ent>
<item>content</item>
<pge key="f">98</pge>

<pge key="f">108</pge>
<pge>110</pge>

<pge key="f">100</pge>
</ent>
<ent>
<item>zero</item>
<pge key="t">210</pge>
</ent>
</idx>
And indexing DTD.
I want to present it as
A B C .... Z
(each hotlinked to the start of that letter).
Then
A (the anchor)
aardvark, page 1,67,79
(say with page 67
-------------------
B
bathtub, page 3,5,7
------------------
Z
zero, page 210
(210 in bold, its the main entry)
etc.
Two pass solution, first sorting, to make data entry easy.
Being lazy, I don't always remember that I've already made
an entry for a particular element, so there are duplicates.
the <item> is duplicated, but the page numbers are not,
hence the 'remove duplicates' approach of keys only partially works.
Hence the Muenchian plus (I think :-).
Question, how to remove the duplicate entries without losing
the page numbers associated with the duplicate?
I found this quite an interesting stylesheet, till I couldn't
figure out the key definitions/usage, then I was stopped.
I have everything except the 'remove duplicates' bit.
Any help appreciated.
Regards daveP
