I'm reading in XML from a file. The file has NO carriage returns in it.
I have set up my php script to print out certain tags along with their attributes and content. For debugging purposes, I have included a default in my switch that prints out any tags that were not printed previously, but with a special note next to them.
What is happening is that aproximately half of my XML is not being displayed. When I say half, I mean that the parent tag is not being displayed, but it's children are.
Here is an example of my XML: (it's not very pretty :-)
<block editable="true" display="show" type="oneimg" number="1"><image align="center" height="144" width="329"><source>http://images.followers.net/sites/SITES0000008/SITES0000008_35.gif</source><alt>Query: SELECT image_description as alt, image_width as width, image_height as height, image_display_path as path FROM imagelibrary WHERE image_name='SITES0000008_35.gif' </alt></image></block>
I'll post the code I'm using below, but the block tags are ignored completely, as are the image tags. However the src and alt tags show fine.
Anyone have any suggestions?
<code>
$currentTag = "";
$attributes = "";
function startElement($parser, $name, $attrs) {
global $currentTag, $attributes;
$currentTag = $name;
$attributes = $attrs;
}
function endElement($parser, $name) {
global $currentTag, $attributes;
$currentTag = "";
$attributes = "";
}
// process data between tags
function characterData($parser, $data) {
global $currentTag, $attributes;
// format the data
switch ($currentTag) {
case "title":
echo "<b>Title:</b> $data <b>Attributes:</b> ";
