Most of these documents are XML documents with a header noting them as
"UTF-8", but the actual data is plain text with the only unusual
elements being hex character encodings (see my earlier post from this
morning asking for a fast way to convert hex encoded entities into
The actual code is too lengthy to post, but in short what it does is:
1. Parses up the XML
2. Runs the data from each element through htmlText to
convert 8859-1 entities
3. Appends the result to a variable
4. Sets the htmlText of a field to that variable for display
If it always crashed in the same spot I'd think it was my code, and
could dive in an fix it.
But since the same code executes with such mixed results it suggests
something deeper is going on but it's been very hard to pin down, hence
my somewhat open-ended inquiry here.
Any and all anecdotes about crahes related to htmlText are likely
helpful. TIA -
