Here's a little something to demonstrate the use of the domxml_attributes function as a method.
It's recurcive and prints out the attributes and some other stuff for each node in an XML doc,
but only content for a text node.
$xmlstr=
'<?xml version="1.0" encoding="iso-8859-1" ?>
<acquaintance>
<addresses>
<address type="home" loc="1 1st st"/>
<address type="office" loc="2 2nd ave"/>
</addresses>
<name>John Doe</name>
</acquaintance>';
function print_data($nodes)
{
while($node = array_shift($nodes)) //cycle through each child node
{
if($node->type=='3') //if node is text print the text
{
//**** See bottom for comment ****
if(ereg('^[[:space:]]*$', $node->content))
continue;
print('NODE:\ntext node content: '.$node->content.'\n\n');
}
else
{
print('NODE:\ntype: '.$node->type.'\n');
print('tagname: '.$node->tagname.'\n');
$many = $node->attributes();
while($attr = array_shift($many)) //cycle through each attribute of the child node
print('attr('.$attr->name.'): '.$attr->value.'\n');
print('\n');
//if child node has children run this function on them
if($sub_nodes = $node->children())
print_data($sub_nodes);
}
}
}
$doc = xmldoc($xmlstr);
$root = $doc->root();
print('ROOT:\ntype :'.$root->type.'\n');
print('tagname: '.$root->tagname.'\n\n');
$nodes = $root->children();
print_data($nodes);
COMMENT:
The XML has line breaks and tabs to get the tags arranged in an organized fashion, so it is easier
to read. But when DOM parses the XML, all the white space between tags is treated like a child node.
So my function would output many "text node content:" lines. So I check for text nodes
that have no content, other than white space (tabs, spaces, line returns), and skip them.
I didn't show the output because this is getting pretty long, so copy and paste it and try it
out!
