replace *except* where...

[Robert Mark Bram]

Hi All,

I have the following to replace newline chars with <br> in a string:

..replace(/\n/g,"<br>")

How can I change this so that it replaces only if there is not already a
"<br>newline" or "newline<p>" combo?

Thanks for any advice!

if(/#$#$#$#/.test(t))alert("error")

t=t.replace(/\n/g,"#$#$#$#")
..replace(/#$#$#$#<p>/g,"\n<p>")
..replace(/<br>#$#$#$#/g,"<br>\n")
..replace(/#$#$#$#/g,"<br>")

// all replaces on one line please !!

not tested

Hello Evertjan!

.replace(/\n/g,"<br>")
How can I change this so that it replaces only if there is not already a
"<br>newline" or "newline<p>" combo?

if(/#$#$#$#/.test(t))alert("error")

t=t.replace(/\n/g,"#$#$#$#")
.replace(/#$#$#$#<p>/g,"\n<p>")
.replace(/<br>#$#$#$#/g,"<br>\n")
.replace(/#$#$#$#/g,"<br>")

// all replaces on one line please !!

#$#$#$# seemed to cause a few problems. Instead of #$#$#$# I used jxjxjxjx
and it works well - thank you very much!

So long as you don't mind losing the unwanted newlines, the simplest thing
would be to remove them before replacing the ones you do want e.g.:

s.replace(/\n*(<(br|p)>)\n*/g, '$1').replace(/\n/g,'<br>')

(split the regex up if you don't want to catch newline<br> and <p>newline
also.)

Although the end tag for a paragraph is listed as optional <url:
http://www.w3.org/TR/REC-html40/struct/text.html#edef-P />, you should get
used to coding a paragraph as:

<p>Paragraph text</p>

rather than:

Paragraph text<p>
