Zdravím
Z url mi linky načíta zo sitemap.xml, ale k nim chcem priradiť aj desription a title. $m = get_meta_tags($g);// nefunguje ak dam premennu echo $m["description"]; <head>
<title>Sitemap URL Scraper</title>
<style type="text/css">
.inputForm {
margin: 1em 0;
padding: 1em;
}
#tblSitemap td {
padding: 0.25em;
}
#tblSitemap {
margin-bottom: 1em;
}
</style>
</head>
<body>
<h1>Sitemap URL Scraper</h1>
<p>A tool to get the URLs in a XML sitemap. This only only handles .XML and not .GZ</p>
<div class="inputForm">
<form name="frmSitemap" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<table id="tblSitemap">
<tr>
<td id="col_1"><label>Sitemap URL:</label></td>
<td id="col_2"><input type="text" name="url" value="" size="60"/></td>
</tr>
<tr>
<td id="col_1">
<input type="submit" name="frmSubmit" value="Submit"/>
</td>
</tr>
</table>
</form>
<?php
if (!isset($_POST['frmSubmit']))
exit;
if (!isset($_POST['url']))
die("Please enter in a URL to the sitemap to be scraped.");
$url = trim($_POST['url']);
if (strlen($url) <= 0)
die("Please enter in a URL to the sitemap to be scraped.");
$pathParts = pathinfo($url);
// Only handles XML files. Not tar gz
if (!in_array($pathParts['extension'], array('xml')))
die("Please enter in a XML file.");
// A better way to do this is to read in chunks
// You should schedule the operation using a cron job
// The preferredm method is to read the file in chunks
// fopen and lock the file
// You fread in n lines and when done close the file
// You keep track of line location by storing the line number in a text file
// You then open the file again and fseek to the offset
// unlock and fclose
//
// Here we do the lazy man's way of using file_get_contents
$strXml = @file_get_contents($url);
if (false == $strXml)
die('Could not open url. Check your spelling and try again');
// So simple using SimpleXml
$sitemap = @new SimpleXmlElement($strXml);
foreach($sitemap->url as $url) {
$u = $url->loc;
$m = get_meta_tags($g);// nefunguje ak dam premennu
echo $m["description"];
echo "<br>";
}
