text parsing question

[Jim Ault]

One solution is below:

Assumption
you are referring to the first instances of 112 & 110 without checking for a
match to the image size attributes (they may not always be present)

Caution: your email version word wraps such that the string
"images/go.png" has a space and cr inserted.  I am assuming this is not what
you meant since it would be a faulty src attribute.

One approach is to END UP with the following and convert cr to spaces:

468
443
112
110
images/go.png

------------stat code--------------------
  put fld 1 into textBlock
  --do this first in case the image name contains "px"
  put offset("src="&quote,textBlock) into srcPos
  --assume possible malformed src string.. note spaces added
  if srcPos = 0 then put offset("src ="&quote,textBlock) into srcPos
  if srcPos = 0 then put offset("src = "&quote,textBlock) into srcPos
  if srcPos = 0 then put offset("src= "&quote,textBlock) into srcPos
  get char srcPos to -1 of textBlock
  replace quote with cr in it
  put line 2 of it into imgStr
  
  --now get the numbers
-- since you cannot always control the format of an html page
  replace cr with space in textBlock  -- these would get in the way
  replace "px" with cr in textBlock
  filter textBlock without empty  --just in case an empty line is created
  replace ":" with space in textBlock
  repeat for each line LNN in textBlock
    put the last word of LNN & cr after thinTextBlock
  end repeat
 --add the imgStr
  put imgStr into line -1 of thinTextBlock
  
  put thinTextBlock into fld 2
end test

----------- end code  --------------
