Import XML into MySQL database - php

Question

I'm new to coding, trying to create a database from an XML file which is a list of industries, company names and symbols. I've seen a few examples of a PHP code that imports the data into MySQL which looked something like:
<?php
$url ="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url); //getting url contents
$data = curl_exec ($ch); //execule curl request
curl_close($ch);
$xml = simplexml_load_string($data);
$con=mysql_connect("localhost", "root", ""); //connect to server
mysql_select_db("symbol_list", $con) or die(mysql_error()); //select database
foreach ($xml -> item as $row) {
$industry = $row -> industry;
$company = $row -> name;
$symbol = $row -> symbol;
// perform sql query
$sql = "INSERT INTO 'symbols_xml' ('industry', 'company', 'symbol')"
. "VALUES ('$industry', '$company', '$symbol')";
$result = mysql_query($sql);
if (!$result) {
echo 'MySQL ERROR';
} else {
echo 'SUCCESS';
}
}
?>
However, because the XML is formatted like this:
<query xmlns:yahoo="http://www.yahooapis.com/v1/base.rng" yahoo:count="215" yahoo:created="2015-03-02T20:58:57Z" yahoo:lang="en-US">
<results>
<industry id="112" name="Agricultural Chemicals">
<company name="Adarsh Plant Protect Ltd" symbol="ADARSHPL.BO"/>
<company name="African Potash Ltd" symbol="AFPO.L"/>
......
</industry>
<industry id="132" name="Aluminum">
<company name="AEI Corp Ltd" symbol="A18.SI"/>
<company name="Alcoa Inc" symbol="AA.BA"/>
<company name="Alcoa Inc" symbol="AA.MX"/>
......
My PHP code above is unable to recognise the values...
Is there any way to import the attributes (industry name, company name and symbol) so that it looks something like:
#| Industry | Company | Symbol
-|----------- ------------ -------
1| Aluminium | Alcoa Inc. | AA.BA
and so on..
I just recently started learning PHP and databases so please forgive me if this is a noobish question that wasted your time. xD
Thanks.

You were actually not very far.
In order to fetch an attribute, you can do it in two ways :
Access it as if the node was an array $node['attributeName']
Use a method named attributes(), and you could also do : $node->attributes()->attributeName;
Here is your code updated :
<?php
$url ="http://query.yahooapis.com/v1/public/yql?q=select%20*%20from%20yahoo.finance.industry%20where%20id%20in%20(select%20industry.id%20from%20yahoo.finance.sectors)&env=store%3A%2F%2Fdatatables.org%2Falltableswithkeys";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_URL, $url); //getting url contents
$data = curl_exec ($ch); //execule curl request
curl_close($ch);
$xml = simplexml_load_string($data);
$con=mysql_connect("localhost", "root", ""); //connect to server
mysql_select_db("symbol_list", $con) or die(mysql_error()); //select database
foreach ($xml->results->industry as $industryNode)
{
foreach ($industryNode->company as $companyNode)
{
$industry = (string) $industryNode['name'];
$company = (string) $companyNode['name'];
$symbol = (string) $companyNode['symbol'];
// perform sql query
$sql = "INSERT INTO 'symbols_xml' ('industry', 'company', 'symbol')"
. "VALUES ('$industry', '$company', '$symbol')";
$result = mysql_query($sql);
if (!$result)
{
echo 'MySQL ERROR';
}
else
{
echo 'SUCCESS';
}
}
}
