Problem with appendChild and ellipsis... [message #173070]

When writing a DOMDocument I have code similar to this...

$title = $doc->createElement("title");
$item->appendChild($title);

$title_data = "Some data followed by an ellipses";

$title_text = $doc->createTextNode($title_data);
$title->appendChild($title_text);

When I look at the resulting file the <title></title> is there but it is
empty. I displayed $title_text->wholeText and the string with the
ellipsis is there. So it appears that something in appendChild is
gagging on the ellipsis.

Any thoughts?

I wonder if there are other characters that might cause a problem.

Ask in an appropriate group. This has *nothing* to do with PHP.

Comp.lang.javascript is --------------> over that way.

Ah, Doug, this IS PHP - not javascript.

I've never seen a problem like this, but then I can't say whether I've
used ellipses or not (if I have, it hasn't been a problem).

Can you post the actual code which is failing (or, if it's too long, a
complete example of the failure)?

Here's a short sample that illustrates the problem...

<?php

foo();
echo "test done<br>";
exit;

function foo()
{
$doc = new DOMDocument();
$doc->formatOutput = true;

$title = $doc->createElement("title");
$doc->appendChild($title);

$title_data = "Some data followed by an ellipses";

$title_text = $doc->createTextNode($title_data);
$title->appendChild($title_text);

$doc->saveXML();
$doc->save("test.xml");

echo "foo done<br>";
}

?>

OK, running your code I get the following messages:

Warning: DOMDocument::saveXML(): string is not in UTF-8 in
C:\temp\domdoctest.php on line 20

Warning: DOMDocument::save(): string is not in UTF-8 in C:\temp
\domdoctest.php on line 21

Your problem is that the character you are using has no UTF-8
equivalent. You can't use characters not in the current charset.

Whenever I need ellipses I just use three periods (...).

BTW - if you had display_errors=on and error_reporting=E_ALL in your
php.ini file you would have seen these messages. I highly recommend
they be enabled on all development systems (but not production).

I thought I did, but I just looked again and it was off. It's on now.

I do too. But the data I am extracting is from a WordPress table. For
some reason the WordPress page/post editor insists on changing three
periods to a single ellipsis. I haven't been able to figure out the
exact steps needed to get it to do this.

Thanks, everything is under control now.

OK, I would take that up with wordpress and see how to disable it -
either that or use a more appropriate charset (what does wordpress use?).

They have this in wp-config.php:

/** Database Charset to use in creating database tables. */
define('DB_CHARSET', 'utf8');

Don't know if there might be other places where the charset is
specified.

No idea - guess you're going to have to ask the wordpress people about it.

You could also look at the one of the pages and see what the charset
being used it. It might give you an idea.

Now that I know the problem, I can work around it. Although they do seem
to have a little inconsistency somewhere. When I see it happen again I
will try to document the steps that caused it and report it as a bug. If
I enter three periods then leave it as three periods.

<meta charset="UTF-8" />

That's in the <head> section? Better if you look at the page's actual
Response Headers, for something like this:

Content-Type: text/html; charset=utf-8

Firefox's Web Developer's Toolbar can give you the capability...

For kicks, try changing your page's head section to:
<meta http-equiv="content-type" content="text/html; charset=iso-8859-1">

...then check again what the Response Headers say. Sometimes (often?) the
server overrules what the HTML says, at least in my experience...

Where is this leading? My problem was not having display_errors turned
on, which would have shown me that the string with the ellipsis was not
utf-8. I solved the latter problem by adding...

if (!mb_check_encoding($title_data, 'UTF-8'))
$title_data = mb_convert_encoding($title_data, 'UTF-8');

Now all is well.

It was a test to make sure your web server was or was not observing your
<meta> element. Just in case.

If I run this code I get this file:

<?xml version="1.0"?>
<title>Some data followed by an ellipses…</title>

.... where … is the entity for ellipsis.

My guess is that you are feeding createTextNode() with the wrong encoding:

http://es2.php.net/manual/en/intro.dom.php

«The DOM extension uses UTF-8 encoding. Use utf8_encode() and
utf8_decode() to work with texts in ISO-8859-1 encoding or Iconv for
other encodings. »

For good typography you should use the correct characters. A " for
example is not a quote sign and ... are just three dots, but not an
ellipsis. But with Unicode you can use all the correct chars instead
of just their ugly ASCII replacements, like „“ and … for example.

Which is usually correct and recommended. You just have an encoding
problem somewhere. And if you don't fix it, it might also happen with
other special chars.
