text between html tags

[btotherunner]

Hello,

iam new in livecode

I want to select parts of a website.
In this parts i need the Text betwenn the html tags to save the Data in a Datastore.

in PHP i use "substr" and "strpos"
$pos1 = (strpos($content, '<h1 class="fl fBold">')+96);
$pos2 = strpos ($content, '</h1>', $pos1);
$ergebnis1 = substr($content, $pos1, $pos2-$pos1);

how do I solve this in live code?

Hi,

1. welcome to the forum!

2. No idea about PHP, but looks like you want to extract any text between 2 html tags:
<h1 class="fl fBold">bla bala bla...</h1>
-> bla bala bla...
Correct?

Then I would use OFFSET to get the number of the first character of the found string:
...
## tHTMLTEXT holds your html source
## Construct start tag with QUOTES -> <h1 class="fl fBold">
put <h1 class=" & QUOTE & "fl fBold" & QUOTE & ">" into tStartString
put "</h1>" into tEndString
put offset(tStartString,tHTMLTEXT) into tStartChar
put offset(tEndString,tHTMLTEXT) into tEndChar
## "move" offset to the correct position:
add length(tStartString) to tStartChar
put char tStartChar to tEndChar of tHTMLTEXT into tErgebnis
...

Well, this is untested and out of my head, but you get the picture

I thought it was:

Code: Select all

set the htmlText of fld 1 to "<b>Your HTML text</b>"
put the text of fld 1 into myVar

fld 1 can be hidden
"put the text" returns.. well the text

Ahh, some tags are not handled like the <Title></Title> tag, look up HTMLText in the dictionary for supported tags.

And it no works correctly with Unicode characters.

ACII values greater then 255 encoded as "bignum" like #12387; work.

Marek, do you have an example page that does not require a specific font to be installed?
I'd like to define my answers better.

Hi guys,

In this parts i need the Text between the html tags* to save the Data in a Datastore.

* <> htmltext!

That was his wish, and this can't be done with just "the text of fld X" after setting its HTMLTEXT.
Besides the fact that this won't work with special characters and unicode!
So my approach might come closest

See my post here and the previous one from Simon:
