if i have a string that has html in it, and i want to remove all the html and just leave the text, how could i do this?
EXAMPLE:
strTEXT = "<font color="red">This is the text</font>
I want it to return "This is the text"
But all the html would be different so i gues it needs to look for < and > and remove everything inbetween it.

why not just replace the < and > with the appropriate html codes for them? &nsbp; i think it is for the <

Because I am working on building a custom search engine for a site and going to have it read in the entire pages html, then remove the html and just display the text if possible to be inserted into the database

You could try something like Filter(string1, "< >", ,-1) - I dont know if that would work or not..... but i'm assuming something along those lines.

havnt tested it, but this SHOULD work.
strPos1 = InStr(String1,"<")
strPos2 = InStrRev(String1, ">")
strCount1 = Left(String1, strPos1)
strCount2 = Right(String1, strPos2)
String1 = strCount1 & strCount2

Just was sitting here doing nothing, so I figured I'd figure out a way for you. I have nothing to test it on, or I'd test it for you.

This isn't fully tested but may give you an idea about one way to go.
Function StripHTML(sIN)
Dim n1, n2
Do while InStr(1, sIN, "<") > 0
n1 = InStr(1, sIN, "<")
n2 = InStr(n1, sIN, ">")
sIN = Mid(sIN, 1, n1-1) & mid(sIN, n2+1, Len(sIN))
Loop
StripHTML = sIN
End Function

Works great. Check it out here..... http://207.21.203.31/test/test_remove_html.asp
It takes the following page and removes the html...
http://207.21.203.31/contact/email.asp
But now that I got what it returns, im trying to figure out how to do this search cause it really brings back to many options. So can yall give me your input?
I am going to make a crawler for the site. I almost have it where it gets all the links on the page which can be viewed at ( http://207.21.203.31/test/test_find_all_links.asp ). This would then cache the pages with html into my database so when a user does a search it can pull up the cache pages and highlight the words they searched for. (like google.com search engine does ) So would I insert the plain text and the html into the database and search in the plain text file and display the html file?

Are you passing the text one line at a time? Try passing the entire page text as one string. The problem may be when <> spans multiple lines, typically with scripts, styles.
Or make some kind of test for a closing ">" tag & if there isn't one in the original line keep throwing away lines until you find a line with the closing tag.

doug,
it actually does everything right ( thanks for the code ). I think the best thing would just be to read the Meta Tags. Have you ever used Google.com's search? How do those search engines get that search working so good? Maybe I will just try it, but it seems to only get the info it really wants.
Look at this page on Google
LINK ON GOOGLE
it says this info at the top of the page...
These search terms have been highlighted: department home contact
These terms only appear in links pointing to this page: menu_title exhibitstore
[/code]
how does it know that menu_title only appears in links pointing to this page. maybe it only reads the info below the </head> tags.
Any other ideaS?
Brad
