Re: HTML to text in field
Possibly as it was lifted verbatim from "elsewhere'. :/
Although it works the way it is in LC 8.1.10.

Re: HTML to text in field
Hi David,
I’m working on something thing similar at the moment (although I’m stripping
out almost everything except for basic HTML formatting).
I too found that nugget by JLG and had the similar results. I’ve also looked at
using XML and regex. The problem with HTML is that while it’s a standard,
unless it’s strict xHtml, it’s not really and a lot of it ends up being
malformed, etc. Todays browsers are very forgiving and figure most of it out,
but if you open the dev tools in safari or firefox and look at most pages, you
will see a LOT of errors.
So I don’t think there is an “out of the box” answer. My solution is similar to
what you are trying, stripping out tags and some other things and cleaning it
up to give me what I want.
If your solution (after fixing the function vs command syntax that Klaus
pointed out) doesn’t work for you, I could put together an example stack using
my “cleaner” to share. I don’t claim it’s the best, only or anything else way
to do it, other than it works for me and am happy to share.
Best,
Steve MacLean

Re: HTML to text in field
Well, although this might sound a bit goofy,
how about just bunging your html text into a scrolling list field and
every time you
came across a moving down to a new line?
This works:
on mouseUp
set the text of fld "SLF1" to empty
answer file "Choose an HTML file to import"
if the result = "cancel"
then exit mouseUp
else
put (URL ("file:" & it),"UTF8") into CHEESE
end if
put 1 into LYNE
repeat until CHEESE is empty
if word 1 of CHEESE is "" then
add 1 to LYNE
delete word 1 of CHEESE
else
put word 1 of CHEESE after line LYNE of fld "SLF1"
delete word 1 of CHEESE
end if
end repeat
end mouseUp
where fld "SLF1" is a scrolling list field.
Admittedly it makes a pig's breakfast out of everything else.
Richmond.

Hello folks,

I don’t want to retain any of the formatting, except line endings, so I would
be happy for tables to appear as lists. I found a little 2013 nugget from the
estimable Jacqueline Landman Gay
set the htmltext of the templatefield to htmlVar -- variable contains the html
string
put the text of the templatefield into tPlainText
In some cases that works fine, but in others, it seems that HTML tables
consisting of maybe 20-30 thousand rows are rendered onto a single line of the
field. A sort of black-letters-overwritten splodge appears in the first row
and LC cranks up to 100% of the processor and BBoD ensues.
Sometimes it never seems to recover, but other times it hands back control
after maybe 20 minutes or so, and in those cases I can see the text if I set
dontwrap to false. It contains no line endings from the original table, and a
shedload of tabs.
I have tried to operate on the HTML string in a variable before putting it into the
field, but frankly don’t really know what property of some HTML tables might mean
that line endings are lost. I can only see when I examine the files in
an editor.
I tried a different approach, replacing a row end with a cr, and then stripping
out tags:
put URL ("file:" & theFilePath) into ttemp
replace "" with cr in ttemp
replaceText (ttemp, "<*>", "|")
filter lines of ttemp without empty
set the text of field "import" to ttemp
The replaceText line generates an error “button "Import HTML": execution error at line 7
(Handler: can't find handler) near "replaceText", char 1”
Firstly I don’t get the error, and secondly I am worried I may be over
complicating something which should be simple.
Advice please!
