I'm trying to figure out how to parse very simple XML files using PHP
4.3. I have been unsuccessful at finding simple explanations of how
to do this.
I found the following code somewhere (can't remember where) and it
works great EXCEPT it does not keep my CSS class tags. The result is
that everything shows up as a <p> rather than <p class="text">, etc.
How do I modify this code to allow this? Or is there a better way to
accomplish this?
TIA
Sue
<?php
$file = "myfile.xml";
$map_array = array(
"bold" => "b",
"emphasis" => "i",
"literal" => "tt"
);
function startElement($parser, $name, $attrs)
{
global $map_array;
if (isset($map_array[$name])) {
echo "<$map_array[$name]>";
}
}
function endElement($parser, $name)
{
global $map_array;
if (isset($map_array[$name])) {
echo "</$map_array[$name]>";
}
}
function characterData($parser, $data)
{
echo $data;
}
$xml_parser = xml_parser_create();
// use case-folding so we are sure to find the tag in $map_array
xml_parser_set_option($xml_parser, XML_OPTION_CASE_FOLDING, true);
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
if (!($fp = fopen($file, "r"))) {
die("could not open XML input");
}
while ($data = fread($fp, 4096)) {
if (!xml_parse($xml_parser, $data, feof($fp))) {
die(sprintf("XML error: %s at line %d",
xml_error_string(xml_get_error_code($xml_parser)),
xml_get_current_line_number($xml_parser)));
}
}
xml_parser_free($xml_parser);
?>
