Formatting HTTML

[lohill]

If I have a chunk of html text in a variable:

tVar="<td align=right>16.2512</td>"

I can say answer tVar and I get a nice looking 16.2512

What operation on tVar will convert tVar to a regular number?

Thanks Larry

Hi.

Can you tell me what you mean by convert to a number?

When a field is set to the htmlText of your string, the value "16.2512" is represented according to the tags attached to the html string.

What do you want to see from that string that is not already there?

Hi Craid,

Can you tell me what you mean by convert to a number?

I guess I mean I want to get rid of all html markings so that I have a number in tVar, something that could be added to another number for example. My actual use is to put the number back into a place in the data grid.

Hi Larry,
Look up isNumber in the dictionary.
and then use a
repeat for each char tChar in tVariable

Hello Simon,

Look up isNumber in the dictionary.
and then use a
repeat for each char tChar in tVariable

I had hoped for something better. If I have to do all that, my preference would be to use offset to get the '>', truncate there and then use offset to get the '<' and then take everything in between.

You guys do too much work to strip off the HTML tags, just use the templateField for quick, in memory processing..

Code: Select all

on mouseUp
  local tVar
  put "<td align=right>16.2512</td>" into tVar
  
  set the htmlText of the templateField to tVar  -- set the htmlText property
  local tVarStripped
  put the text of the templateField into tVarStripped  -- grab the plain text that would be displayed
  
  put tVarStripped
  reset the templateField  -- reset so creating a new field does not have your htmlText in it..
end mouseUp

shaosean,

Wow. It works, but it is going to take me some time to figure out what happened.

Just make it a function that you can reuse..

Code: Select all

function htmlToText pHtml
  set the htmlText of the templateField to pHtml
  local tReturn
  put the text of the templateField into tReturn
  reset the templateField
  return tReturn
end htmlToText

Hi Sean,

...just use the templateField for quick, in memory processing...

DAMN!
I use MetaCard/Revolution/Livecode for over 12 years now and still learn something new almost every day!

Thanks a lot for this little gem!
