ASP - asp innerText?

asp innerText?

in DHTML, body.innerText nicely strips out the raw textual contents of a
formatted page. Is there a straighforwards way to do this with a server-side
ASP function (e.g. on a string containing the HTML) ? It is to fill a
database field used for a simple search routine.
I don't have permission on this server to use 3rd party components, it's
plain IIS6.
Thanks.

Use a Regular Expression.

RegExp is a black art to me! Off the top of the head,
delete from "<head" to "/head>"
delete from "<style" to "/style>" (in case not in head)
delete from "<script" to "/script>" (in case not in head)
replace anything in chevrons with nothing.
replace line-breaks with spaces
replace multiple spaces with single spaces
replace HTML entities with literals
Does that sound about right?
thanks, Giles

Somewhat to me as well ...
A couple people in this group (Chris Hohmann comes to mind) have it down
pretty well. There are some websites out there that provide libraries of
regular expression patterns.

I guess so, but why are you leaving the closing and opening brackets?

If you can, you might consider using the Indexing Services instead of
rolling your own search routine.

http://www.codeproject.com/asp/indexserver.asp

If that's not an option, you should be able to use Internet Explorer
from an ASP.

<% Option Explicit

Dim ie: Set ie = CreateObject("InternetExplorer.Application")
ie.Navigate "about :blank"

Dim doc: Set doc = ie.Document
doc.open
doc.writeln "<dl>"
doc.writeln "<dt>em</dt>"
doc.writeln "<dd>Indicates <em>emphasis</em></dd>"
doc.writeln "<dt>strong</dt>"
doc.writeln "<dd>Indicates <strong>stronger emphasis</strong></dd>"
doc.writeln "</dl>"
doc.close

Response.ContentType = "text/plain"
Response.Write doc.documentElement.InnerText
%>

With ASP you have complete control over the content of the page before it
gets written so it's not clear to me why you would need to do this ...
