I've been trying to get a php class to write into xml... I've looked around and all the code seems the same to the below and everyone i have tried is coming up with the same error msg..
Warning: domdocument() expects at least 1 parameter, 0
Has anyone else had this problem? Does anyone know of an answer?
Thanks
Reading an XML File using PHP
XML Code: file name - employees.xml
<?xml version="1.0" encoding="iso-8859-1"?>
<employees>
<employee>
<name>Mark</name>
<age>27</age>
<salary>$5000</salary>
</employee>
<employee>
<name>Jack</name>
<age>25</age>
<salary>$4000</salary>
</employee>
</employees>
<?php
$doc = new DOMDocument();
$doc->load( 'employees.xml' );
$employees = $doc->getElementsByTagName( "employee" );
foreach( $employees as $employee )
{
$names = $employee->getElementsByTagName( "name" );
$name = $names->item(0)->nodeValue;
$ages= $employee->getElementsByTagName( "age" );
$age= $ages->item(0)->nodeValue;
$salaries = $employee->getElementsByTagName( "salary" );
$salary = $salaries->item(0)->nodeValue;
echo "<b>$name - $age - $salary\n</b><br>";
}
?>
With the above XML file the PHP code will read the XML file and retrieve the information from it and output that in the screen.
Writing XML using PHP
<?php
$employees = array();
$employees [] = array(
'name' => 'Albert',
'age' => '34',
'salary' => "$10000"
);
$employees [] = array(
'name' => 'Claud',
'age' => '20',
'salary' => "$2000"
);
$doc = new DOMDocument();
$doc->formatOutput = true;
$r = $doc->createElement( "employees" );
$doc->appendChild( $r );
foreach( $employees as $employee )
{
$b = $doc->createElement( "employee" );
$name = $doc->createElement( "name" );
$name->appendChild(
$doc->createTextNode( $employee['name'] )
);
$b->appendChild( $name );
$age = $doc->createElement( "age" );
$age->appendChild(
$doc->createTextNode( $employee['age'] )
);
$b->appendChild( $age );
$salary = $doc->createElement( "salary" );
$salary->appendChild(
$doc->createTextNode( $employee['salary'] )
);
$b->appendChild( $salary );
$r->appendChild( $b );
}
echo $doc->saveXML();
$doc->save("write.xml")
?>
This code will output the XML file in console as well as it will create a XML file in the name of write.xml in the same directory of the PHP script.
As i don't know much about perl it is not wise to comment about that. I think PHP is enough for this purpose.
