HELP, really stuck, php xml parser handling &amp;

khan2265

i have a tag in my xml thats like

<address>something university &amp; something somewhere</address>

does anyone know why when the xml parser hits &
my tag_content gets called more than once; why is that? how do i fix it?

xml_parser_set_option($this->xml_parser, XML_OPTION_CASE_FOLDING, true);
xml_set_element_handler($this->xml_parser, "start_tag", "end_tag");
xml_set_character_data_handler($this->xml_parser, "tag_contents");

Because the tag's content is split into several consecutive nodes in the parse tree; one for the text before the entity, one for the entity, and one for the text after the entity. That's so that entities can be parsed properly.

so the & is an entity?...

how would I parse it so that it comes out on one line?

i tried putting htmlspecialchars($data), but it still comes out as three lines...

my head hurts =(

function tag_contents($parser, $data)
{

if ($this->current == "ADDRESS")
{
 echo htmlspecialchars($data)."<BR/>";
 //array_push($this->address1, addslashes("$data") );
}
}

while($data = fread($fp, filesize($this->xml_file)))
		{
			$data = eregi_replace(">"."[[:space:]]+"."<","><",$data);
			if (!xml_parse($this->xml_parser, $data, feof($fp)))
			{
		    	die(sprintf("XML error: %s at line %d",
		    	xml_error_string(xml_get_error_code($this->xml_parser)),
		    	xml_get_current_line_number($this->xml_parser)));
		    }
        }

Sorry for not replying sooner - I (like lots of people) don't live in the same timezone that you do.

Yes.

You'll need to join those nodes together as you go. Because they're parsed as separate nodes, you'll need to buffer the text (the address in this case), and attach text and entities to it as you go. You can decode entities as you parse them (which is why they're parsed separately - the XML reserved entities are already decoded for you). I dunno what your character_data handler looks like, but presumably you're saving the data it's passed somewhere. If you can't append the character data there piece by piece, then keep all of the character data you've read for the element until you get to the end of the element, then save it all at once. (You'd have to do this anyway, in case the chunk of XML you sent to the parser was incomplete and stopped in the middle of a text node).
