RE: Convert HTML to plain text -- RPG400-L

I didn't see how you were actually producing the html. We have gone the XSLT route for all our printing. RPG program generates XML, then XSL can process this and output HTML or PDF. No more letters that look like they're written on typewriters for us!

I wish but on. This will be something that will be with us
for years. What would really be nice is a printer that
understands html. Then just spool out the html generated
using your favorite way to do html and send it to a spool
file and let the driver format and print it. For the printer
manufacture it would probably be any harder than PJL or PDF
or Postscript

If this is a once-off request, life gets simpler ...

... display the HTML page as normal in a browser, copy the
page using ctrl-c then paste and the work is done for you.

Thanks Vern. Looked at the samples, might go that way

although while it

does work I find it very difficult to get the code to work

and coming back

later to look at it in 6 months I get totally lost with

what it is doing

and how/why it works. /<\s*\/?\s*span\s*.*?>/g makes no

sense to my brain.

But that is my brains problem and might be the best

solution. I usually

prefer to go with code that is a bit more "wordy".

Here is a very simple sample of what is in the field in the

database. It

is not a full html page from <html> to </html> it is just a

snippet of

code in html format. This one only has to deal with

but the code

could have s and <li>s and a few other goodies if

they format the

text to look nicer (indents, bullet lists, etc) It will

never be the full

suite of html, only a small subset which makes it easier.

I did the code already to put this into 80 characters

chucks or a ,

whichever occurs first and wrote a line to the print file

which resulted

in this.

Can easily deal with the & but I think the fun will be

the word wrap.

I may need to parse the string into words and join words

together until

the length of what is joined plus the length of the next

word exceeds 80,

then write a line.

Mike

No code, just questions!

Is the HTML in a PF or in a STMF? The latter is preferable,

methinks. I

can see a couple things to do - first look for closing tags

- scan for

"</" - and the scan back for the matching opening tag. Then

take on the

unary (my term) tags like .

There's also the need, perhaps, to take out <html> and

<head> and not the

contents of <body>.

Or maybe, as I get from another site, it's enough to strip

everything

between "<" and ">" in that order - unless you have

comparison operators

in there! Sites in the google below discuss these issues.

I did a quick google on "strip html tags". One link -

http://weblogs.asp.net/rosherove/archive/2003/05/13/6963.aspx
- discusses

using regular expressions. Another -

http://nadeausoftware.com/articles/2007/09/php_tip_how_strip_h
tml_tags_web_page

- discusses issues about text you still want inside some tags.

Looks as if grep or sed or the like could do the work, with

an appropriate

expression. And those are callable from RPG or CL through QSH.

collected using

a rich-text editor on a web page that is stored as HTML in

a variable

length field. Works great when the form is on a webpage as it is a

put in the

rich-text editor shows on the web page exactly as entered.

Problem is

taking that html code and printing it using a normal print

file to an

outq then the printer. Stripping out the html tags might

not be too bad.

Dealing with tags and tags and<ul><li> can be a bit more
challenging but I think word wrap is going to be the

hardest. The print

file line is 80 characters and I need to be sure to not

break a word

between lines. Some tricky code and I thought I would just

see if anyon!

e !

might have done this already and would share their code.
