How do I find all text containing a word in an AutoCAD drawing?

What cadssistant does

1. Selects TEXT and MTEXT whose string (group code 1) matches *REV* with one ssget filter.
2. Grip-highlights the matches in the drawing and reads their handles, layers and contents back.
3. Replies with a table. The highlight stays until you press Esc. Say "replace REV B with REV C in those" and it edits the same handles.

The same task in AutoLISP

(progn
  (setq ss (ssget "_X" '((0 . "TEXT,MTEXT") (1 . "*REV*"))))
  (if ss (sssetfirst nil ss))
  (if ss (sslength ss) 0))

Selects and grip-highlights the matches; returns how many. MTEXT longer than 250 characters continues in group code 3, which this filter doesn't search.

Good to know

• Wildcards follow wcmatch: * for any run of characters, ? for one, # for a digit, [A-C] for a range.
• Block attributes are not TEXT entities. Say "in attributes too" and it walks each block's ATTRIB entities as well.
