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.
