Re: Convert HTML to plain text

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 <br>.

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_html_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.

Would anyone happen to have RPG code to take HTML and strip off all the tags and just have plain text that would be printed using normal print files? I have a form that needs to be displayed on a web page and also printed from an RPG application. Part of the form is data 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 what-you-see-is-what-you-get function. Any special editing 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<br> tags and<p> 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 anyone !
might have done this already and would share their code.

Thanks
