sgrep (structured grep) is a tool for searching and indexing text,
|
|
SGML,XML and HTML files and filtering text streams using structural
|
|
criteria. The data model of sgrep is based on regions, which are
|
|
nonempty substrings of text. Regions are typically occurrences of
|
|
constant strings, SGML-tags, or meaningful text elements, which
|
|
are recognizable through some delimiting strings or the builtin
|
|
SGML, XML and HTML parser. Regions can be arbitrarily long,
|
|
arbitrarily overlapping, and arbitrarily nested.
|
|
|
|
Sgrep is a convenient tool for making queries to almost any kind
|
|
of text files with some well kown structure. These include programs,
|
|
mail folders, news folders, HTML, SGML, etc... With relatively
|
|
simple queries you can display mail messages by their subject or
|
|
sender, extract titles or links or any regions from HTML files,
|
|
function prototypes from C or make complex queries to SGML files
|
|
based on the DTD of the file.
