NAME

   xmlsort - sorts 'records' in XML files

SYNOPSIS

     xmlsort -r=<recordname> [ <other options> ] [ <filename> ]

     Options:
      -r <name>  name of the elements to be sorted
      -k <keys>  child nodes to be used as sort keys
      -i         ignore case when sorting
      -s         normalise whitespace when comparing sort keys
      -t <dir>   buffer records to named directory rather than in memory
      -m <bytes> set memory chunk size for disk buffering
      -h         help - display the full documentation

     Example:
      xmlsort -r 'person' -k 'lastname;firstname' -i -s in.xml >out.xml

DESCRIPTION

   This script takes an XML document either on STDIN or from a named file
   and writes a sorted version of the file to STDOUT.  The "-r" option
   should be used to identify 'records' in the document - the bits you
   want sorted.  Elements before and after the records will be unaffected
   by the sort.

OPTIONS

   Here is a brief summary of the command line options (and the
   XML::Filter::Sort options which they correspond to).  For more details
   see XML::Filter::Sort.

   -r <recordname> (Record)
       The name of the elements to be sorted.  This can be a simple
       element name like 'person' or a pathname like 'employees/person'
       (only person elements contained directly within an employees
       element).

   -k <keys> (Keys)
       Semicolon separated list of elements (or attributes) within a
       record which should be used as sort keys.  Each key can optionally
       be followed by 'alpha' or 'num' to indicate alphanumeric of numeric
       sorting and 'asc' or 'desc' for ascending or descending order (eg:
       -k 'lastname;firstname;age,n,d').

   -i (IgnoreCase)
       This option makes sort comparisons case insensitive.

   -s (NormaliseKeySpace)
       By default all whitespace in the sort key elements is considered
       significant.  Specifying -s will case leading and trailing
       whitespace to be stripped and internal whitespace runs to be
       collapsed to a single space.

   -t <directory> (TempDir)
       When sorting large documents, it may be prudent to use disk
       buffering rather than memory buffering.  This option allows you to
       specify where temporary files should be written.

   -m <bytes> (MaxMem)
       If you use the -t option to enable disk buffering, records will be
       collected in memory in 'chunks' of up to about 10 megabytes before
       being sorted and spooled to temporary files.  This option allows
       you to specify a larger chunk size.  A suffix of K or M indicates
       kilobytes or megabytes respectively.
