问题
I am confused. How can I access tags inside CDATA?
XML Code:
<body>
<block>
<![CDATA[
<font color="#FFCC53" size="+6"><b>Latest News Updates</b></font>
<font color="#AAAAAA">HTML Formatted Text Fields</font>
]]>
</block>
</body>
PHP Code:
<?php
$xml = simplexml_load_file("main.xml");
print ( $xml->smallTextList[0]->item[0]->textBody[0]->font[0] ) ;
?>
I am using this, but I am getting a blank screen....

Your problem is that your font tags are inside of CDATA. Since CDATA stands for "Compiled Data", PHP should treat it as a "block of non-parsed data." It should not (and cannot) let you read those as tags. You'll probably have to do something like:
$xml = simplexml_load_file("main.xml");
$inner = simplexml_load_string(
'<fk>' . // you have to wrap the CDATA in a tag, otherwise it will break.
// not sure about asXML. You may be able to get away without it.
$xml->block[0]->asXML() .
'</fk>'
);
print $inner->font[0];
Your problem, of course, is that CDATA will let things in which are not valid XML, like < or >, but this seems to be your best option...
