Stripping some data from XML field using php - php

Question

I've currently got an XML file that's being imported using a plugin on WordPress.
I've got a field that's currently importing the data and time automatically, but the field contains data in the current format
<EndDate>2014-04-24T00:00:00+01:00</EndDate>
I need to remove the time field somehow, but I'm stuck on how to do this (using php).
Is there a way of creating a function to remove the time, so that the field pulls in;
<EndDate>YYYY-MM-DD</EndDate>
Please help.

Answer 1

You first need to exactly locate that field. You could use simplexml.
To output a formatted date you use the date function. It accepts a UNIX timestamp.
You obtain that timestamp by using the strtotime function, that takes a date+time formatted as a string and returns a UNIX timestamp.

Here is one way you can do what you are looking at
$xml = "<reservation>
<detail>
<name>XXXXX</name>
<EndDate>2014-04-24T00:00:00+01:00</EndDate>
</detail>
<detail>
<name>YYYYY</name>
<EndDate>2014-04-24T00:00:00+01:00</EndDate>
</detail>
</reservation>";
$data = simplexml_load_string($xml);
//rint_r($data);
foreach ($data->detail as $obj)
{
$end_date = $obj->EndDate ;
$date = new DateTime($end_date);
$obj->EndDate = $date->format("Y-m-d");
}
$new_xml = $data->asXML();
echo $new_xml ;
You can also save as file
$data->asXML($file);
I have used for loading the string as
$data = simplexml_load_string($xml);
You can load the file also as
$data = simplexml_load_file($file);

Xpath can be used so fetch nodes from the XML DOM, but it can extract scalar values, too. It has even some functions. One of them is string-before() that returns the part of a string before an substring.
$xml = "<EndDate>2014-04-24T00:00:00+01:00</EndDate>";
$dom = new DOMDocument();
$dom->loadXml($xml);
$xpath = new DOMXpath($dom);
var_dump(
$xpath->evaluate('substring-before(//EndDate, "T")')
);

string(10) "2014-04-24"
