I am interested in knowing of any:
1) software that can do ad hoc queries for data from
ASCII SGML files

2) query and manipulation languages
that might be suitable for ASCII SGML files.

3) Indexers for elements and attributes.


I do not recall much discussion on using ASCII SGML documents
as data bases, so this might be new territory.


I know that there are a few systems that handle query
capability, but they all seem to want to convert the
file into a database.  That is no bueno for me - the
files must stay ASCII files.


If proprietary interests are involved, please advise.


I have thrown a few query examples together to help explain
my interest:
(pardon the SQL look-alike, I don't get out often enough)

> select content from 321.memo
>   where gi = "subject";
SGML query program

> select attr from 321.memo
>   where gi = "memo" and attr = "nbr";
pmh1223

to retrieve the subject and id from a memo.
   
   OR

> select memo.subject, "\t", memo[nbr] from 321.memo;
SGML query program     pmh1223

where content is implied if the item specified is a GI
and attribute value is implied if the item is an attribute.

The DTD for memo might look like

<!ELEMENT   memo    - -  (date,to, from, subject) >
<!ATTLIST   memo         nbr  CDATA  #IMPLIED     >
<!ELEMENT   subject - -  (#PCDATA)                >
.
.
.


Thanks.

BTW, my email has been a little dull lately, so even
flames are welcome.


Ciao 4 Now.
