XML_Parse_Into_Struct()

HelloWorld · #1 (**permalink**) 10-28-2007, 09:54 PM

Code:

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

PHP Code:

  <?php

//invalid xml file

$xmlfile = 'test.xml';

$xmlparser = xml_parser_create();

 
// open a file and read data

$fp = fopen($xmlfile, 'r');

$xmldata = fread($fp, 4096);

 
xml_parse_into_struct($xmlparser,$xmldata,$values);

 
xml_parser_free($xmlparser);

print_r($values);

?>

Here's what I found after a little bit of research, this method can return me:

Code:

Array
(
[0] => Array
  (
  [tag] => NOTE
  [type] => open
  [level] => 1
  [value] =>
  )
  [1] => Array
    (
    [tag] => TO
    [type] => complete
    [level] => 2
    [value] => Tove
    )
[2] => Array
  (
  [tag] => NOTE
  [value] =>
  [type] => cdata
  [level] => 1
  )
  [3] => Array
    (
    [tag] => FROM
    [type] => complete
    [level] => 2
    [value] => Jani
    )
[4] => Array
  (
  [tag] => NOTE
  [value] =>
  [type] => cdata
  [level] => 1
  )
  [5] => Array
    (
    [tag] => HEADING
    [type] => complete
    [level] => 2
    [value] => Reminder
    )
[6] => Array
  (
  [tag] => NOTE
  [value] =>
  [type] => cdata
  [level] => 1
  )
  [7] => Array
    (
    [tag] => BODY
    [type] => complete
    [level] => 2
    [value] => Don't forget me this weekend!
    )
[8] => Array
  (
  [tag] => NOTE
  [value] =>
  [type] => cdata
  [level] => 1
  )
[9] => Array
  (
  [tag] => NOTE
  [type] => close
  [level] => 1
  )
)

But how do you access each of them? That's what I'm confused lol.. I'm not sure on how does this work? Please give me easy example, thanx a lot!!!

how do you access this part only?

Code:

[0] => Array
  (
  [tag] => NOTE
  [type] => open
  [level] => 1
  [value] =>
  )

I posted it here:

The output indicates it's an array. The index you've requested is 0, so you can access those values with $values[0]. For one of the sub-attributes, you'd use $values[0][tag], for example.

Thanx a lot TeraTask, this is the way PHP deals with multi dimentional arrays...

I have to add something: wow. I wasn't aware of xml_parse_into_struct!

I still like the PEAR routine though as it provides easier-to-use results.

LOL, I did some research on PHP.net and saw this thing, so I checked it out since I knew that Struct is some kind of data structure.. ^^
