extracting a log file which has xml in it - php

Question

I have a log file whose content is like the one below
2016-04-07 19:37:48 <order merchant="asc" affiliate="" id="UM9E-C01101518" date="1443723720" event_id="1" ref="GDVJT" alias="asc">
<event type="sale" date="2015-10-01 18:22:00" status_code="SA">
<sale amount="61.45" amount_usd="43.94" method="VISA" currency="CAD" processor="visa"/>
<tax amount="7.37" amount_usd="5.28" currency="CAD"/>
<payout amount="39.89" currency="USD"/>
</event>
<customer>
<name>Frank</name>
<email>frank#gmail.com</email>
<address/>
<region>BC</region>
<country>IN</country>
<zip_postal>V8V1J9</zip_postal>
<phone_number>1231231234</phone_number>
<language>EN</language>
<ip>209.13.233.227</ip>
<currency>CAD</currency>
</customer>
I am trying to extract the value of name and email from this log file.
I am using the below code:
$handle = fopen('vendorOrder.log','r') or die ('File opening failed');
while (!feof($handle)) {
$dd = fgets($handle);
$str = htmlentities($dd, ENT_XHTML);
if(preg_match("/<name>(.*)<\/name>/",$str)){
$txt = getTextBetweenTags($str, "name");
echo $txt;
}
}
fclose($handle);
function getTextBetweenTags($string, $tagname) {
$pattern = "/<$tagname>(.*)<\/$tagname>/";
preg_match($pattern, $string, $matches);
return $matches[0];
}
But it is never matching the name tag and I am not able to get the value between the tags.
I need the output as Frank.
Can someone let me know whats wrong in the code

Answer 1

Use simplexml_load_file() php function.
Example:
$xml=simplexml_load_file("vendorOrder.log") or die("Error: Cannot create object");
And get this value with $xml->customer->name
Maybe your XML are crashed. Try this format.
<order merchant="asc" affiliate="" id="UM9E-C01101518" date="1443723720" event_id="1" ref="GDVJT" alias="asc">
<event type="sale" date="2015-10-01 18:22:00" status_code="SA">
<sale amount="61.45" amount_usd="43.94" method="VISA" currency="CAD" processor="visa"/>
<tax amount="7.37" amount_usd="5.28" currency="CAD"/>
<payout amount="39.89" currency="USD"/>

Yup as stated use simplexml_load_file($url) ; to parse xml.
you can find examples here : http://www.w3schools.com/php/php_xml_simplexml_get.asp

Make a correction in original string with something like this:
<?php
$xml_file = 'vendorOrder.log';
$xml_content = file_get_contents( $xml_file );
$xml_content .= "\n</order>";
$xml_content = substr( $xml_content, 20 );
var_dump($xml_content);
$xml=simplexml_load_string($xml_content) or die("Error: Cannot create object");
echo $xml->customer->name;
