how to read xml element attribute

Recommended Posts

I have modified a free third party php script to display an xml feed.  What I now need to do is display the date, which is an attribute of an element.    <FS NAME="date" VALUE="2006-05-11" />  How do I display the date?  The code is below.  Thanks in advance!

[pre]<?

//$headline_style = 'news';
$headline_style = '';
$description_style = '';
$feed_url = '';
$show_detail = false;
$insideitem = false;
$tag = "";
$title = "";
$date = "";
$description = "";
$link = "";
$image = "";
$insideimage = false;
$max = 3;
$count = 0;

function render_news($feed_url, $showdetail, $headlinestyle, $detailstyle) {
global $show_detail, $headline_style, $detail_style, $max, $count, $insideitem, $insideimage;
$insideitem=false;
$insideimage=false;
$count = 0;
$show_detail = $showdetail;
$headline_style = $headlinestyle;
$detail_style = $detailstyle;

$xml_parser = xml_parser_create();
xml_set_element_handler($xml_parser, "startElement", "endElement");
xml_set_character_data_handler($xml_parser, "characterData");
$fp = @fopen($feed_url,"r")
  or die("Error reading xml data.");
if ($fp) {
while ($data = fread($fp, 4096))
  xml_parse($xml_parser, $data, feof($fp))
  or die(sprintf("XML error: %s at line %d", 
  xml_error_string(xml_get_error_code($xml_parser)), 
  xml_get_current_line_number($xml_parser)));
fclose($fp);
} else {
echo '<span class="'. $detail_style .'">Feed is temporarily not available</span>';
}

// Free up memory used by the XML parser
xml_parser_free($xml_parser);
}


function startElement($parser, $name, $attrs) {
global $insideitem, $tag, $title, $description, $link, $date, $image, $insideimage;
if ($insideitem || $insideimage) {
$tag = $name;
}
if ($name == "R" ) {
$insideitem = true;
}
if ($name == "IMAGE") {
$insideimage = true;

}
}

function endElement($parser, $name) {
global $insideitem, $tag, $title, $description, $link, $image, $date, $insideimage, $show_detail, $headline_style, $detail_style, $count, $max;

if ($name == "do not use....") {
echo '<img src="'. htmlspecialchars(trim($image)) .'" /><br /><br />';
$insideimage=false;
$image="";
} else if ($name == "R") { //&& $count < $max) {
//$count++;
printf('<a href="%s" class="'. $headline_style .'" target="_blank"><b>%s</b></a><br />',trim($link),trim($title));
if ($show_detail)
printf('<span class="'. $detail_style .'">%s</span><br />%s<br />',trim($description), trim($date));
else {
echo "<br /><br />";
}
$title = "";
$description = "";
$date = "";
$link = "";
$insideitem = false;
} else if ($count >= $max) {
$title = "";
$description = "";
$link = "";
$insideitem = false;
}
}

function characterData($parser, $data) {
global $insideitem, $tag, $title, $description, $link, $date, $image, $insideimage;
if ($insideimage) {
switch ($tag) {
case "U":
$image .= $data;
break;
}
}
if ($insideitem ) {
switch ($tag) {
case "T":
$title .= $data;
break;
case "S":
$description .= $data;
break;
case "FS":
$date .= $data;
break;
case "U":
if (!is_string($link)) $link="";
$link .= $data;
break;
}
}
}
?>[/pre]

For those interested, the solution is this:

Add global variable $date1 to beginning of script and to lists of global variables in all functions.  Also change the variable in the endElement() function to be $date1 instead of $date .  See bold below for final change:

function startElement($parser, $name, $attrs) {
global $insideitem, $tag, $title, $description, $link, $date, [b]$date1[/b], $image, $insideimage;
[b]if ($insideitem || $insideimage) {
if ($name == "FS") {$date1 = $attrs["VALUE"];}
else {$tag = $name;}
} [/b]
if ($name == "R" ) {
$insideitem = true;
}
if ($name == "IMAGE") {
$insideimage = true;

}
}
