Editing an XML sitemap with PhP

mramonster

The code below works fine except that it doesn't break lines or add tabs.

<?php
$xml = simplexml_load_file("sitemap-1.xml"); //This line will load the XML file.

$sxe = new SimpleXMLElement($xml->asXML()); //In this line it create a SimpleXMLElement object with the source of the XML file.
//The following lines will add a new child and others child inside the previous child created.
$person = $sxe->addChild("url");
$person->addChild("loc", "http://www.mysite.com/omg-new-url.html");
$person->addChild("lastmod", "2009-02-13");
//This next line will overwrite the original XML file with new data added
$sxe->asXML("sitemap-1.xml"); 
?>

//It comes out like this:
   <url>
      <loc>http://www.mysite.com/old-url.html</loc>
      <lastmod>2009-02-13</lastmod>
   </url><url><loc>http://www.mysite.com/omg-new-url.html</loc><lastmod>2009-02-13</lastmod></url>

//Instead of like this:
   <url>
      <loc>http://www.mysite.com/old-url.html</loc>
      <lastmod>2009-02-13</lastmod>
   </url>
   <url>
      <loc>http://www.mysite.com/omg-new-url.html</loc>
      <lastmod>2009-02-13</lastmod>
   </url>

Doing Either of these (or variations) does not work:

<?php
$xml = simplexml_load_file("sitemap-1.xml"); //This line will load the XML file.

$sxe = new SimpleXMLElement($xml->asXML()); //In this line it create a SimpleXMLElement object with the source of the XML file.
//The following lines will add a new child and others child inside the previous child created.
$person = $sxe->addChild("url")."\n";
$person->addChild("loc", "http://www.mysite.com/omg-new-url.html")."\n";
$person->addChild("lastmod", "2009-02-13")."\n";
//This next line will overwrite the original XML file with new data added
$sxe->asXML("sitemap-1.xml"); 
?>


<?php
$xml = simplexml_load_file("sitemap-1.xml"); //This line will load the XML file.

$sxe = new SimpleXMLElement($xml->asXML()); //In this line it create a SimpleXMLElement object with the source of the XML file.
//The following lines will add a new child and others child inside the previous child created.
$person = $sxe->addChild("url\n");
$person->addChild("loc", "http://www.mysite.com/omg-new-url.html\n");
$person->addChild("lastmod", "2009-02-13\n");
//This next line will overwrite the original XML file with new data added
$sxe->asXML("sitemap-1.xml"); 
?>

Shouldn't really matter: it's still the same XML. If it's breaking something then it's the reader that's at fault.

That said, look at the [man]DOM[/man] extension instead: the DOMDocument object has a $formatOutput property.
