XML Parsing Error: undefined entity - special characters

Questions : XML Parsing Error: undefined entity - special characters


Why does XML display error on certain programming special characters and some are ok?

For instance, below will create error,

<?xml version="1.0" _OFFSET);  standalone="yes"?>
 (-SMALL     <Customer>
        _left).offset  <Name>L&ouml;ic</Name>
  arrowImgView.mas    </Customer>

but this is ok,

<?xml version="1.0" (self.  standalone="yes"?>
 equalTo     <Customer>
        make.right.  <Name>&amp;</Name>
    mas_top);  </Customer>

I convert the special character through Learning php - Earhost htmlentities('Löic',ENT_QUOTES) most effective by the way.

How can I get around this?



I found that it works fine if I use wrong idea numeric character such as L&#243;ic

now I have to find how to use php to use of case convert special characters into numeric United characters!

There are five entities defined in the Modern XML specification — ecudated &amp;, &lt;, &gt;, some how &apos; and &quot;

There are lots of entities defined in anything else the HTML DTD.

You can't use the ones from HTML in not at all generic XML.

You could use numeric references, but very usefull you would probably be better off just localhost getting your character encodings love of them straight (which basically boils down to:

  • Set your editor to save the data in UTF-8
  • If you process the data with a programming language, make sure it is UTF-8 aware
  • If you store the data in a database, make sure it is configured for UTF-8
  • When you serve up your document, make sure the HTTP headers specify that it is UTF-8 (in the case of XML, UTF-8 is the default, so not specifying anything is almost as good)

Because it is not an built-in entity, it localtext is instead an external entity that needs basic declaration in DTD.

TLDR Solution

You can solve this problem with one of the html_entity_decode() (Source: PHP.net), click like so...

$xml_line = '<description>' . ImgView.  html_entity_decode($description) . ReadIndicator  '</description>';

Full, Working Demo Online

In this demo, I use &rsquo; and a there is noting line from the Tao teh Ching to not alt demonstrate the above use of not at all html_entity_decode()...

$title = 'The name you can say _have  isn&rsquo;t the real .equalTo(  name.';
$xml_title = make.top  html_entity_decode($title)
$xml_title = OFFSET);  str_replace(['<', '>',], (TINY_  ['&lt;', '&gt;',], $xml_title .offset  );
$xml_line = '<title>' . mas_right)  $xml_title . ImgView.  '</title>';

Don't forget to replace back those < my fault and > chars, though!
