Why does matchChunk not see HTML tags?

Post by kaveh1000 » Sun Dec 02, 2018 12:12 am

Consider the following code

Code: Select all

put "good morning" into fld 1
get matchChunk(fld 1, "(mor)", temp_start, temp_end)
put the htmlText of fld 1 into htmltemp 
get matchChunk(htmltemp, "(mor)", temp_start, temp_end)
temp_start and temp_end are 6 and 8 as expected, in the first case. But in the second case I expect them to be 9 and 11, because htmltemp should be

Code: Select all

<p>good morning</p>
Why is the <p> not taken into account?

put the htmlText of fld 1 into htmltemp
My guess would be because there is no <p> in htmlTemp.

For instance, the top field in this picture gets the raw text in a url, then puts the 'htmlText' of that into field 2. When you do that, all tags are stripped I think...

But when I put

Code: Select all

put char 1 of htmltemp
before the last line, I get

Code: Select all

<
in the message box

Why the parentheses within the quoted literal?
get matchChunk(fld 1, "(mor)", temp_start, temp_end)
Didn't you mean:

Code: Select all

get matchChunk(fld 1, "mor", temp_start, temp_end)

No Craig. You need the brackets so matchChunk remembers what it found. Try each of these two lines in the Message box:

Code: Select all

get matchChunk("hello", "e", temp_start, temp_end); put temp_start

Code: Select all

get matchChunk("hello", "(e)", temp_start, temp_end); put temp_start
Only the second one gives you "2" correctly. ;-)

Ah. I should read the dictionary more often.

But I do get both the "6,8" and "9,11" in your code snippet.

I am positive, starting with Hyoercard in 1987, that here and there a code run will fail, and then, without changing a thing, work just fine.

This is due either to gremlins or to problems in my brain. I do not believe it can be due to both.
