[PHP] Invalid Characters, XML...

[Luis Lebron]

Here's what I have been using.


$trans= array("'" => "&#39;", "'" => "&#39;",">" => "&#62;", "<" => "&#60;",
"&" => "&#38;","-" => "&#45;", "°" => "&#176;", "±" => "&#177;", "-" =>
"–", """ => "“", """ => "”","..." => "…","'" =>
"‘","²" =>"&#178;","·" => "&#183;" );

$value=strtr($value,$trans);

This should get you started. It behaves as does htmlentities().

For those high-ASCII characters out of Word/IE... decide what regular ASCII
character you want to map them to, (eg slanted-quote-open and -close to
regular quote), and add them to the $trans array before performing the
array_walk().

function xmlentities ($string, $quote_style = ENT_COMPAT)
{
static $trans;
if (!is_array ($trans)) {
$trans = get_html_translation_table (HTML_ENTITIES, $quote_style);
array_walk ($trans, create_function ('&$a, $b', '$a = "&#" . ord ($b) .
";";'));
}
return (strtr ($string, $trans));
}

I had a similar problem recently, but was not able to work with it in PHP
tho. The array for that mapped characters to their entity turned out to be
HUGE and it took forever to evaluate long XML files.

I ended up killing several birds with one stone by wrapping the html-tidy
utility (tidy.sourceforge.net) in php. It validates xml, converts all
characters >127 into their respective entity, pretties up the XML output,
cleans up Word 2000 specific content and deals with a variety of
input/output encodings. It did all these a lot faster that any of the
scripts I had written and saved me from writing others.

Im using PHP to write to XML files, but I am having some problems. A lot of
users are cutting and pasting content from text editors like word, which
uses odd quotation marks, dashes, etc. which PHP writes to the XML file, and
then the XML parser does not under stand. Is there a
stripslashes() or htmlspecialchars() equivalent that will convert this kind
of stuff to the correct ascii text?
