sgmldiff - Find differences in the markup of two SGML
files
SYNOPSIS
sgmldiff [ options ...] file1 file2 [ [ -a] [
--attributes]
[ -c [ [ attributes] [ nesting] [ textpos] ] ] [
--context [ [ attributes] [ nesting] [ textpos] ] ]
[ -s] [ --statistics]
[ -h] [ --help]
[ -v] [ --version] ]
DESCRIPTION
This perl script allows to determine the structural dif
ferences between two SGML files. It compares the files,
regardless of what is in between the tags, to only focus
on the markup. Its output is similar to diff(1).
The typical use of sgmldiff is to compare an SGML file
with its translation into another language. If the trans
lation was done cleanly, sgmldiff returns without finding
any difference in the markup.
An example of a typical call to sgmldiff is:
sgmldiff english.sgml italiano.sgml
If there are differences in markup between both files,
sgmldiff will output a series of differences reports sum
marized with lines of the form:
169a164
At line 169 of the first file, line 164 of the sec
ond file has been added.
8a12,15
At line 169 of the first file, lines 12 to 15 of
the second file have been added.
41d28 Line 41 of the first file has been destroyed, to
obtain line 28 of the second file.
63,66d61
Lines 63 to 66 of the first file have been
destroyed. to obtain line 61 of the second file.
52c51 Line 52 of the first file has been changed into
5,7c8,10
Lines 5 to 7 of the first file have been changed
into lines 8 to 10 of the second line. In addition
to those summaries, the lines of the first file are
shown preceeded by '<' and the lines of the second
file are shown preceeded by '>".
OPTIONS
Here is the list of actions that can be requested to
sgmldiff:
[ [ -a] [ --attributes] ]
Include the attribute values in the difference tests.
Don't set this value if the attributes are likely to be
translated. Set this value if the attributes value
shouldn't change between both files. Default is to don't
include the attributes in the difference tests.
[ [ -c [ [ attributes] [ nesting] [ textpos] ] ] [
--context [ [ attributes] [ nesting] [ textpos] ] ] ]
Add more context to the difference. Since every test
between the tags is removed before testing the differ
ences, sgmldiff is likely to resynchronize itself at the
wrong place, by thinking the location in both files corre
spond, while it's not true. By adding more context to the
compared area, such risk is disminished.
The allowed values for the --context option are:
attributes
Take into account the attribute names. The
attribute values are controlled by the attributes
option.
nesting
Take into account the nesting level of all the com
pared tags.
textpos
Take into account the position in the text.
[ [ -s] [ --statistics] ]
iPrint some SGML information at the end.
[ [ -h] [ --help] ]
[ [ -v] [ --version] ]
Print the version identifier and exit
