Hi,
I'm trying to write a script that will extract the value of an
attribute from an element using the attribute value of another element
as the basis for extraction.
For example, in my situation I have a pre-defined list of main sections
and I want to extract the id attribute of the form element and create a
dictionary of graphic ID and section number pairs but only for the
sections in my pre-defined list but I want to exclude the id value from
any section that does not appear on my list. I.e., I want to know the
id value for the forms that appear in sections 1 and 3 but not in 2.
Boiled down my SGML looks something like this:
<main-section no="1">
<form id="graphic_1.tif">
<form id="graphic_2.tif">
<main-section no="2">
<form id="graphic_3.tif">
<main-section no="3">
<form id="graphic_4.tif">
<form id="graphic_5.tif">
<form id="graphic_6.tif">
This is what I have come up with on my own so far. My problem is that I
can't seem to pick up the value of the id attribute.
Any advice appreciated.
Greg
