Parsing - Reading data within a tag

[Steve]

Hi,

I am new to XML and PHP and have a question that I hope someone could
answer.

Some background on my problem.
I am receiving an XML message over TCP/IP and need to access data
within the tags of the message.

Message example:
<message title="begin"
no="1"><descrip tion>Start</description></message>
Now I know I can get the data from the description tag by:

$xmlstr =<<<EOT
<message title="begin"
no="1"><descrip tion>Start</description></message>
EOT;

$xml = simplexml_load_ string($xmlstr) ;
echo ($xml->description[0]);
My question is, how do I access 'title' or 'no' ?
Is it possible?

I cannot change the format of the data sent to me.
I am using PHP 5.0.5

Any help is appreciated.

Also, is this the best way of parsing the XML message?

Thank you

Steve

The SimpleXML functions convert an XML document into a nested data
structure in one operation, but this could require a fair chunk of
memory, depending on the size and complexity of the XML data.

The basic XML functions, however, provide an event-based parsing scheme.
i.e. the parser reads from top to bottom, and every time an element is
opened or closed, a user-defined function is called. This allows you to
perform necessary processing without chewing up large amounts of memory.
