Now that I've thought of a potential practical use for XML, I'm actually trying to implement it.
I've read through (skimmed, really) the PHP & XML articles on devshed, in the XML section... and I've been playing around with using the XML DOM, but have a few questions.
My XML document looks something like this:
Code:
<?xml version="1.0"?>
<SITE>
<SECTION1>
<PAGE1>This is the first page of section 1.</PAGE1>
<PAGE2>This is the second page of section 1.</PAGE2>
<PAGE3>This is the third page of section 1.</PAGE3>
</SECTION1>
<SECTION2>
<PAGE1>This is the first page of section 2.</PAGE1>
</SECTION2>
</SITE>
Now, I'm using the DOM to extract the root, and then list all of the children of the root. However, what's happening is that even though I have 2 children of the 'SITE' node, my code is reporting that there are more. I've checked the type for these other nodes, and they say they're text objects, but I can't figure out what they are.
Here's my code:
PHP Code:
$xmlFile = "C:\\My Documents\\XML\\xmldoc.xml";
$xmlDoc = xmldocfile($xmlFile);
$docRoot = $xmlDoc->root();
print("The document root tag is: <i>" . $docRoot->name . "</i><br><br>\n");
$docChildren = $docRoot->children();
print("There are <b>" . sizeof($docChildren) . "</b> children to the Document Root Tag.<br>\n");
print("<UL>\n");
foreach($docChildren as $currChild)
{
if ($currChild->type == 1)
print("<LI> Type: " . $currChild->type . " | " . $currChild->name);
else if ($currChild->type == 3)
print("<LI> Type: " . $currChild->type . " | " . $currChild);
}
print("</UL>\n");
The output looks like:
Warning: Unexpected character in input: ' ' (ASCII=11) state=1 in
c:\my documents\xml\testxml.php on line
45
The Document Root Tag is:
SITE
There are
5 children to the Document Root Tag.
- Type: 3 | Object
- Type: 1 | SECTION1
- Type: 3 | Object
- Type: 1 | SECTION2
- Type: 3 | Object
So my first question is, why am I getting that 'Unexpected character in input' error?
Secondly, what
are those three other 'objects'? What are they used for?
Can anyone help me out?
Thanx,
