I want to replace innertext of a XML node my XML file named test.xml is
<?xml version="1.0" encoding="utf-8"?>
<ads>
<loop>no</loop>
<item>
<description>Description 1</description>
</item>
<item>
<description>Text in item2</description>
</item>
<item>
<description>Let play with this XML</description>
</item>
</ads>
I want to change the value of loop and
description tag both,
and it should be saved in test.xml like:
<?xml version="1.0" encoding="utf-8"?>
<ads>
<loop>yes</loop>
<item>
<description>Description Changing Here</description>
</item>
<item>
<description>Changing text in item2</description>
</item>
<item>
<description>We will play later</description>
</item>
</ads>
I tried code in PHP:
<?
$file = "test.xml";
$fp = fopen($file, "rb") or die("cannot open file");
$str = fread($fp, filesize($file));
$dom=new DOMDocument();
$dom->formatOutput = true;
$dom->preserveWhiteSpace = false;
$dom->loadXML($str) or die("Error");
//$dom->load("items.xml");
$root=$dom->documentElement; // This can differ (I am not sure, it can be only documentElement or documentElement->firstChild or only firstChild)
$loop=$root->getElementsByTagName('loop')->item(0);//->textContent;
//echo $loop;
if(trim($loop->textContent)=='no')
{
echo 'ok';
$root->getElementsByTagName('loop')->item(0)->nodeValue ='yes';
}
echo "<xmp>NEW:\n". $dom->saveXML() ."</xmp>";
?>
I tried only for loop tag.I don't know how to replace nodevalue in
description tag.
When I run this page it shows output like:
ok
NEW:
<?xml version="1.0" encoding="utf-8"?>
<ads>
<loop>yes</loop>
<item>
<description>Description 1</description>
</item>
<item>
<description>Changing text in item2</description>
</item>
<item>
<description>Let play with this XML</description>
</item>
</ads>
It gives the value yes in browser but don't save it in test.xml any reason?
