SGMLDIFF(1)                                                        SGMLDIFF(1)




NAME

       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 differences 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 trans-
       lation into another language. If  the  translation  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 summarized  with  lines  of  the
       form:

       169a164
              At  line  169 of the first file, line 164 of the second file has
              been added.

       8a12,15
              At line 8 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 line 51 of the
              second file.

       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 differ-
              ence 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  differences,  sgmldiff  is
              likely  to  resynchronize itself at the wrong place, by thinking
              the location in both files correspond, while it’s not  true.  By
              adding  more  context to the compared area, such risk is dismin-
              ished.

              The allowed values for the --context option are:

              attributes
                     Take into account the attribute names. The attribute val-
                     ues are controlled by the attributes option.

              nesting
                     Take  into  account the nesting level of all the compared
                     tags.

              textpos
                     Take into account the position in the text.

                    [ -s | --statistics ]
              Print some SGML information at the end.

                    [ -h | --help ]
              Print a short help message and exit

                    [ -v | --version ]
              Print the version identifier and exit
