From WIKI: PCDATA Simply speaking, PCDATA stands for Parsed Character Data. That means the characters are to be parsed by the XML, XHTML, or HTML parser. (< will be changed to <, <p> will be taken to mean a paragraph tag, etc). Compare that with CDATA, where the characters are not to be parsed by … Read more
There is no XML CDATA equivalent in JSON. But you can encode your message in a string literal using something like base64. See this question for more details.
The two options are almost exactly the same. Here are your two choices: <html>This is <b>bold</b></html> <html><![CDATA[This is <b>bold</b>]]></html> In both cases, you have to check your string for special characters to be escaped. Lots of people pretend that CDATA strings don’t need any escaping, but as you point out, you have to make sure … Read more
Note: I’m the EclipseLink JAXB (MOXy) lead and a member of the JAXB (JSR-222) expert group. If you are using MOXy as your JAXB provider then you can leverage the @XmlCDATA extension: package blog.cdata; import javax.xml.bind.annotation.XmlRootElement; import org.eclipse.persistence.oxm.annotations.XmlCDATA; @XmlRootElement(name=”c”) public class Customer { private String bio; @XmlCDATA public void setBio(String bio) { this.bio = bio; … Read more
You can just store it as a text or attribute value; no escaping or CDATA sections needed. The standard base 64 characters + and / (other than a-z, A-Z and 0-9) do not interfere with XML parsing at all.
Got it! I adapted the code from this great solution (archived version): <?php // http://coffeerings.posterous.com/php-simplexml-and-cdata class SimpleXMLExtended extends SimpleXMLElement { public function addCData( $cdata_text ) { $node = dom_import_simplexml( $this ); $no = $node->ownerDocument; $node->appendChild( $no->createCDATASection( $cdata_text ) ); } } $xmlFile=”config.xml”; // instead of $xml = new SimpleXMLElement( ‘<site/>’ ); $xml = new SimpleXMLExtended( … Read more
The CDATA structure isn’t really for HTML at all, it’s for XML. People sometimes use them in XHTML inside script tags because it removes the need for them to escape <, > and & characters. It’s unnecessary in HTML though, since script tags in HTML are already parsed like CDATA sections. Edit: This is where … Read more
You’re probably not accessing it correctly. You can output it directly or cast it as a string. (in this example, the casting is superfluous, as echo automatically does it anyway) $content = simplexml_load_string( ‘<content><![CDATA[Hello, world!]]></content>’ ); echo (string) $content; // or with parent element: $foo = simplexml_load_string( ‘<foo><content><![CDATA[Hello, world!]]></content></foo>’ ); echo (string) $foo->content; You might … Read more
You have to break your data into pieces to conceal the ]]>. Here’s the whole thing: <![CDATA[]]]]><![CDATA[>]]> The first <![CDATA[]]]]> has the ]]. The second <![CDATA[>]]> has the >.
All text in an XML document will be parsed by the parser. But text inside a CDATA section will be ignored by the parser. CDATA – (Unparsed) Character Data The term CDATA is used about text data that should not be parsed by the XML parser. Characters like “<” and “&” are illegal in XML … Read more
