XML to MySQL using PHP

Posted on 2009-05-19

Hello, I need to import XML data to a MySql database. The XML follows this pattern:

<hotel>
  <hotel_ref>12345</hotel_ref>
  <hotel_name>The Budget Hotel</hotel_name>
  <hotel_star>5</hotel_star>
  <hotel_address>50-60 Main Road</hotel_address>
  <hotel_city>London</hotel_city>
  <hotel_county>Greater London</hotel_county>
  <hotel_pcode>NW8 1RF</hotel_pcode>
  <hotel_description>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque quis eros sapien, id lobortis nunc. Lorem ipsum dolor sit amet, consectetur adipiscing elit.</hotel_description>
  <hotel_directions>Sed a dolor in orci tincidunt luctus. Aliquam erat volutpat. Praesent nec magna ac mauris euismod rutrum non eget mauris. </hotel_directions>
  <hotel_link>http://www.example.com</hotel_link>
  <hotel_rooms>201</hotel_rooms>
  <images>http://www.example.com/test.jpg</images>
- <geo_code>
  <long>-0.12173</long>
  <lat>51.51998</lat>
  </geo_code>
  <hotel_distance>0.8718</hotel_distance>
  <rating>5</customer_rating>
  <prices_from>100.00</prices_from>
  <star>Lorem Ipsem</star>
  <accomodation_type>Hotel</accomodation_type>
  <rack_rate>300.00</rack_rate>
</hotel>

 Using some recycled code (from a solution elsewhere on this site) I can get most of the data into my database, but NOT the data in the <geo_code></geo_code> nodes - which i need to go in corresponding fields in MySQL latitude and longitude.

Could somebody please help me with a pointer on how to extract that data?

Here's the code i'm using....

Thanks!


<?php
 
ini_set('display_errors', 1);   # enable PHP error reporting
error_reporting(E_ALL);
 
 
 mysql_connect("localhost", "root", "") or die(mysql_error());
 
mysql_select_db("xmltest") or die(mysql_error());
 
$xmlfile = "hotels.xml";
 
$dom = new DOMDocument;
$dom->load($xmlfile);
 
$items = $dom->getElementsByTagName('hotel');  # find all <hotel> elements
foreach($items as $item) {
  $record = array();
  foreach($item->childNodes as $child) {
    if($child->nodeType == XML_ELEMENT_NODE)  # elements within each <hotel>
      $record[] = $child->nodeName." = '".
        mysql_real_escape_string(trim($child->nodeValue))."'";
  }
  echo '<pre>insert into hotels set '.implode(",\n  ",$record).'</pre>';
}
 
?>

Do you want to use script or tools? You may use Navicat to do the xml import - which is a very efficient way of doing. Script is definitely a good option - but then we need to spend time in checking the code. :(

Hello iamanindian,

I need to use a PHP script as this is part of a bigger application.

Thanks for the Navicat suggestion I have looked at that before.

This is currently the output from the code above:

hotel_ref = 12345
hotel_name = The Budget Hotel
hotel_star = 5
hotel_address = 50-60 Main Road
hotel_city = London
hotel_county = Greater London
hotel_pcode = NW8 1RF
hotel_description = Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque quis eros sapien, id lobortis nunc. Lorem ipsum dolor sit amet, consectetur adipiscing elit.
hotel_directions = USed a dolor in orci tincidunt luctus. Aliquam erat volutpat. Praesent nec magna ac mauris euismod rutrum non eget mauris.
hotel_link = http://www.example.com 
hotel_rooms = 201
images = http://www.example.com/test.jpg
geo_code =
hotel_distance = 0.8718
rating = 5
prices_from = 100.00
star = Lorem Ipsem

rack_rate = 300.00

I'll take a look at this, but before I do, let me make a comment about the geocode.  A geocode is a two field, comma-separated string with ALWAYS latitude first, and longitude last.  So while the XML will isolate it correctly, there is a small risk that future coding would not work as expected.

OK
<geo_code>
  <long>-0.12173</long>
  <lat>51.51998</lat>
  </geo_code>

WRONG
$geocode = "-0.12173,51.51998";

Hello Ray,
Thanks for looking into this for me :)
In response to your point about geocode formatting for me it is not an issue on this occasion because, instead of extracting them as a comma separated string, i would prefer to have them as 2 separate entities so that I can put them into a database field each (Latitude and Longitude)
Kind regards,
Howard

So, ideally my output from the script would be like this:


hotel_ref = 12345
hotel_name = The Budget Hotel
hotel_star = 5
hotel_address = 50-60 Main Road
hotel_city = London
hotel_county = Greater London
hotel_pcode = NW8 1RF
hotel_description = Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque quis eros sapien, id lobortis nunc. Lorem ipsum dolor sit amet, consectetur adipiscing elit.
hotel_directions = USed a dolor in orci tincidunt luctus. Aliquam erat volutpat. Praesent nec magna ac mauris euismod rutrum non eget mauris.
hotel_link = http://www.example.com 
hotel_rooms = 201
images = http://www.example.com/test.jpg
latitude = 51.51998
longitude = -0.12173
hotel_distance = 0.8718
rating = 5
prices_from = 100.00
star = Lorem Ipsem
accomodation_type = Hotel
rack_rate = 300.00

10-4.  Just be sure if you present these values to a mapping service as a geocode that you have them in the right order.

RIGHT
$geocode = "51.51998,-0.12173";

Example:
http://maps.google.com/maps?f=q&source=s_q&hl=en&geocode=&q=51.51998,-0.12173&sll=38.93877,-77.096736&sspn=0.107618,0.2314&ie=UTF8&z=16&iwloc=A

Thanks for the points!  As you can see, I like SimpleXML much better than DOMDocument.  FWIW, I like RESTful services better than SOAP, too.  But that's a separate issue...

I had to change this from the OP:
<customer_rating>5</customer_rating>

Other than that, it's pretty faithful to the example.  Best of luck with it, ~Ray

Sorry about the error in the OP :(

I like simpleXML too.. i haven;t got my head around DOM at all yet.

Thanks again and best wishes.
