DESCRIPTION

18       This perl script allows to determine the structural differences between
19       two SGML files. It compares the files, regardless of what is in between
20       the tags, to only focus  on  the  markup.  Its  output  is  similar  to
21       diff(1).
22
23       The  typical use of sgmldiff is to compare an SGML file with its trans‐
24       lation into another language. If  the  translation  was  done  cleanly,
25       sgmldiff returns without finding any difference in the markup.
26
27       An example of a typical call to sgmldiff is:
28
29             sgmldiff english.sgml italiano.sgml
30
31
32       If  there  are  differences in markup between both files, sgmldiff will
33       output a series of differences reports summarized  with  lines  of  the
34       form:
35
36       169a164
37              At  line  169 of the first file, line 164 of the second file has
38              been added.
39
40       8a12,15
41              At line 8 of the first file, lines 12 to 15 of the  second  file
42              have been added.
43
44       41d28  Line  41 of the first file has been destroyed, to obtain line 28
45              of the second file.
46
47       63,66d61
48              Lines 63 to 66 of the first file have been destroyed. to  obtain
49              line 61 of the second file.
50
51       52c51  Line  52  of the first file has been changed into line 51 of the
52              second file.
53
54       5,7c8,10
55              Lines 5 to 7 of the first file have been changed into lines 8 to
56              10  of  the  second  line.   In addition to those summaries, the
57              lines of the first file are shown preceeded by '<' and the lines
58              of the second file are shown preceeded by '>".

OPTIONS

61       Here is the list of actions that can be requested to sgmldiff:
62
63                    [ -a | --attributes ]
64              Include the attribute values in the difference tests.  Don't set
65              this value if the attributes are likely to  be  translated.  Set
66              this value if the attributes value shouldn't change between both
67              files. Default is to don't include the attributes in the differ‐
68              ence tests.
69
70                    [  -c   [  attributes | nesting | textpos ] | --context  [
71       attributes | nesting | textpos ] ]
72              Add more context to the difference. Since every test between the
73              tags  is  removed  before  testing  the differences, sgmldiff is
74              likely to resynchronize itself at the wrong place,  by  thinking
75              the  location  in both files correspond, while it's not true. By
76              adding more context to the compared area, such risk  is  dismin‐
77              ished.
78
79              The allowed values for the --context option are:
80
81              attributes
82                     Take into account the attribute names. The attribute val‐
83                     ues are controlled by the attributes option.
84
85              nesting
86                     Take into account the nesting level of all  the  compared
87                     tags.
88
89              textpos
90                     Take into account the position in the text.
91
92                    [ -s | --statistics ]
93              Print some SGML information at the end.
94
95                    [ -h | --help ]
96              Print a short help message and exit
97
98                    [ -v | --version ]
99              Print the version identifier and exit
