I have the following sitemap XML which contains a list of URLs to be submitted for search engines. I took this example code from another SO answer.
// Init XMLWriter
$writer = new XMLWriter();
$writer->openURI(APPLICATION_PATH . '/sitemap.xml');
// document head
$writer->startDocument('1.0', 'UTF-8');
$writer->setIndent(4);
$writer->startElement('urlset');
$writer->writeAttribute('xmlns', 'http://www.sitemaps.org/schemas/sitemap/0.9');
// Write something
// this will write: <url><loc>some url here; SO not allowed me</loc></url>
$writer->startElement('url');
$writer->writeElement('loc', 'some url here; SO not allowed me');
$writer->endElement();
// end urlset
$writer->endElement();
// end document
$writer->endDocument();
This code creates a new sitemap using XML writer. I want to append new url to existing urlset using XMLReader
$reader = new XMLReader();
if (!$reader->open('sitemap.xml')){
die("Failed to open 'sitemap.xml'");
}
while($reader->read()){
if ($reader->nodeType == XMLReader::ELEMENT && $reader->name == 'urlset') {
$writer->startDocument('1.0', 'UTF-8');
$writer->startElement('url');
$writer->writeElement('loc', 'http://www.test.com');
$writer->endElement();
break;
}
}
$reader->close();
I could not find proper samples on how to update xml file with XMLreader. How can I rewrite this code so that it appends new URLs to url set tag using XMLreader?
Edit 1:
I have this xml sitemap,
<?xml version="1.0" encoding="UTF-8"?>
<urls>
<url>
<loc>http://www.bbc.com</loc>
</url>
</urls>
I want the program to add one new url at the urls tag like this eg. adding URL google.com,
<?xml version="1.0" encoding="UTF-8"?>
<urls>
<url>
<loc>http://www.bbc.com</loc>
</url>
<url>
<loc>http://www.google.com</loc>
</url>
</urls>
How could I get this functionality or is there some other helpers like DOMDocument or simplexml to do that in PHP? Any references to others sites is also welcome.
