NAME
stag-autoschema - writes the implicit stag-schema for a stag fileSYNOPSIS
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-schemastag-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

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 beforehandContenus ©2006-2024 Benjamin Poulain
