If I have some text in a field, I can use the "charIndex" property (see
Dictionary) to obtain teh character position of the first character of a
For example, if the field contains:
The quick brown fox jumps over the lazy dog. The lazy dog was named "Oz".
The lazy dog was a great dog.
Then there are 3 instances of "lazy dog"
trueWord 8 to 9 of the field, 11 to 12, and 17 to 18
You can also determine that first instance "lazy dog" is in sentence 1
to 1 (or just sentence 1) of the field, the 2nd is in sentence 2, and
the 3rd in sentence 3
And you can determine that the first 2 instances are in paragraph 1 and
the 3rd instance of "lazy dog" is in paragraph 2 (using the trueWord,
sentence, and paragraph chunk types)
charIndex lets me determine the start of a sentence or paragraph, such as:
the charIndex of sentence 1 to 1 of fld X --> 1 and the charIndex of
sentence 2 of fld X --> 46 and the charIndex of sentence 3 of fld "X" --> 75
the charIndex of paragraph 1 of fld X --> 1 and the charIndex of
paragraph 2 of fld X --> 75
My question is, charIndex appear to ONLY work on an actual field object
(visible or invisible). You get execution errors if you try say:
put the charIndex of word 8 of the text of the templateField
put the charIndex of word 8 of the templateField
put the charIndex of word 8 of tVar
Does anyone know of a clever way to do the equivalent of the charIndex
for an arbitrary chunk expression for a container/variable (i.e. not an
actual field object)?
