Thank you, thats useful

GOOD WORK!

So how would you read an xml file modify an attribute and then save the new xml using this helper?

Farhad, this helper does not XML parsing.

superb

how to make it output encoding too with xml_dom()?

In the helper, replace

DOMDocument('1.0');

by

DOMDocument('1.0', 'iso-8859-1')

Excelente!!

THIS IS A GREAT..

Hi. I have a problem.

Call to a member function createElement() on a non-object in \application\helpers\MY_xml_helper.php on line 52

Can you help me?

I ran into the same error (member function createElement() on a non-object) when I was trying to produce xml with nested elements. For example, for this xml result:

<?xml version="1.0"?>
<book>
<author>
<birthdate>1948-04-04</birthdate>
</author>
</book>

The code is as follows:

$xml = xml_dom();
$book = xml_add_child($xml, 'book');
$author = xml_add_child($book,'author');
xml_add_child($author,'birhtdate','1948-04-04');

Note that the formatting is kind of messy in my comment above, hopefully this is still helpful.

I would like to get data from xml file. How could I do that? If you could give me a favour, please exlpain.

Good tutorial

For those getting a message similar to ... "Call to a member function createElement() on a non-object in" ... try the following...

When adding a child to a child of the dom, for some reason it was getting hung up while trying doc owner. The solution was to modify the help and my method calls so that Im pass the xml_dom additionally when calling xml_add_child or xml_add_attribute.

Replace the functions with the following ...


function xml_add_child($dom, $parent, $name, $value = NULL, $cdata = FALSE)
{
$child = $dom->createElement($name);
$parent->appendChild($child);

if($value != NULL)
{
if ($cdata)
{
$child->appendChild($dom->createCdataSection($value));
}
else
{
$child->appendChild($dom->createTextNode($value));
}
}

return $child;
}



function xml_add_attribute($dom, $node, $name, $value = NULL)
{
$attribute = $dom->createAttribute($name);
$node->appendChild($attribute);

if($value != NULL)
{
$attribute_value = $dom->createTextNode($value);
$attribute->appendChild($attribute_value);
}

return $node;
}

Thanks man!! you saved a life of a Brazilian hehehe!!

<numberOfAdults>2</numberOfAdults>
<numberOfChildren>2</numberOfChildren>
<childAges>5,7</childAges>
</Room>
</RoomGroup>
</HotelRoomAvailabilityRequest>

Can you help me?

FYI, in xml_add_child() $name has to be a valid XML name. If you pass it something invalid, you'll get:

Fatal error: Uncaught exception 'DOMException' with message 'Invalid Character Error' in system/application/helpers/MY_xml_helper.php

Adding this into xml_add_child() helps to sanitize the name so it doesn't fail:

$name = preg_replace('/[^\w0-9-]/', '', $name);

It'd be great to have an XML sanitize function to make names valid. :)

this is good...
