newline dropped by HTML

[Xiaochuan Fang]

I just tried sending the String like this:
tempText = (tempText + "<font color=white>\nXXX\n</font>");

It actually inserts the XXX and it changes the color, but do you
THINK it will obey \n? Not on your life.

What is the 'HTML processor'?Browser?
Are you talking about '<BR>'?

That's standard HTML behaviour. Any number of whitespace-Chars (\n,
\r, tab, space, ...) not marked as PCDATA is compacted to only one
whitespace. To get around this use &nbsp; for spaces and <br /> for
new-lines.

I am stumped. I send Java String to an HTML processor method that
renders the text into pretty browser text. Fine, it works, it is
so colorful and so dashing that it takes my breath away.

But wait, what about multi-line text sent to the HTML method as a
single String? The HTML appears to be dropping the newlines that
I append to the Java String. I append "\n" after each line is
read, concatenate the lines, and send them off to the processor. I
end up with a one-liner as if I never had appended the newlines.

Of course this works when output goes to display. Of course!

I think I have to come up with a scheme to add the HTML tags before
sending it to the HTML processor method. Or something like that.
I don't even know if that makes sense since tags added on a line by
line basis may screw things up worse.

Here's a sample line from the HTML processor method where I insert
a String called answerText. You can see that sending "extra" HTML
is a bit of a weird concept, but I have no clue what else to try.

sb.append("<a href=\"#\" onMouseover=\"div" + divNum +
".innerHTML=\'" + answerText + "\'\" onMouseout=\"div" + divNum +
".innerHTML=\'\'\">\n");

Aha! Thanks.

(I knew that, right?)

Big Aha!

Red faced, I limp back to insert the stupid tag that I could have
inserted instead of the gargantuanly stupid (is that a word?)
<font> tag.

Another useful tag is <pre>, for "preformatted". Wrap it around your
text with line breaks and the browser will break the lines as expected.

That is sweet, Chris. I had not heard of that tag.

Alternatively, check out http://www.w3schools.com/.

Castro's book may be excellent -- I wouldn't know, as I've never read
it. On the other hand, w3school is free, and it was "good enough" for
learning HTML for me.

The reasons I like Castro's book are that it:

- gives a clear, well-written tutorial introduction to all the
main features of HTML.
- documents common proprietary extensions, portability issues
and work-rounds
- has examples that only need an ASCII editor and a web browser to
work through them.
- contains excellent reference sections that link back to
relevant parts of the tutorials. Its the only reference I need.
- is cheaper than most computer books.
