line-basedtools like awk, sed, shells, aren't very good at handling xml because they're not recursive parsers. (Well, it parses THEIR language recursively, but doesn't parse text they read in recursively -- things like yacc do..) Usually you'd use a language like perl or python and load an xml module. Could you tell us what your actual goal is instead of the way you want to do it?

stag-autoschema

STAG-AUTOSCHEMA(1p)					User Contributed Perl Documentation				       STAG-AUTOSCHEMA(1p)

NAME

       stag-autoschema - writes the implicit stag-schema for a stag file

SYNOPSIS

	 stag-autoschema -w sxpr sample-data.xml

	 stag-autoschema -dtd sample-data.xml

DESCRIPTION

       Takes a stag compatible file (xml, sxpr, itext), or a file in any format plus a parser, and writes out the implicit underlying stag-schema

       stag-schema should look relatively self-explanatory.

       Here is an example stag-schema, shown in sxpr syntax:

	 (db
	  (person*
	   (name "s"
	   (address+
	    (address_type "s")
	    (street "s")
	    (street2? "s")
	    (city "s")
	    (zip? "s")))))

       The database db contains zero or more persons, each person has a mandatory name and at least one address.

       The cardinality mnemonics are as follows:

       +   1 or more

       ?   0 or one

       *   0 or more

       The default cardinality is 1

ARGUMENTS

       -p|parser FORMAT
	   FORMAT is one of xml, sxpr or itext, or the name of a perl module

	   xml assumed as default

       -dtd
	   exports schema as DTD

       -w|writer FORMAT
	   FORMAT is one of xml, sxpr or itext, or the name of a perl module, OR DTD

	   The default is sxpr

	   note that stag schemas exported as xml will be invalid xml, due to the use of symbols *, +, ? in the node names

LIMITATIONS

       not event based - memory usage becomes exhorbitant on large files; prepare a small sample beforehand
