First of all I have no idea  how to do this. But I know it can be done. A little help would be alot for me.

 

Thank you in advance.

 

So I want to go through a sitemap and visit each of the link on the sitemap and save the URL on to a database.

 

Example:

 

HP 5550N A3 Colour Laser Printer

 

 

Konica Minolta PagePro 1350W A4 Mono Laser Printer

 

 

HP 9050dn A3 Mono Laser Printer

 

 

HP 5550DTN A3 Colour Laser Printer

 

 

HP 5550HDN A3 Colour Laser Printer

 

 

HP 5550DN A3 Colour Laser Printer

 

Lets say this was on the sitemap and it just continues with other product like this. I want to write a code where it will go to the first link and saves the product URL on to the database and continues to do the same until the last link. On my example it would be HP 5550DN A3 Colour Laser Printer.

 

Any help??? Any ideas??

 

I am not asking someone to write the code for me.. Just need help and good direction  :)

for something simple:

simplexml()

 

<?php
//test url http://www.domain.com/sitemap.xml
//test url http://www.phpfreaks.com/sitemap.xml
if(isset($_GET['url']) && $_GET['url'] != ''){
$url = trim($_GET['url']);
$xml = simplexml_load_file($url);

foreach ($xml->url as $url_list) {
    $url_array[] = $url_list->loc;  
}

//display the array
foreach($url_array as $urls){
echo "<a href='$urls'>$urls</a><br />";
}

} else {
echo "No xml url inserted";
}
?>

make the php file , use in the address bar something like http://mysite.com/script.php?url=http://www.phpfreaks.com/sitemap.xml

Now that you have the array full of urls you can insert them into a database however you want, AUTO_INCREMENT per id, or serialize or implode the array into a field per each sites xml file

 

To grab the titles can use curl() or file_get_contents()

 

I have a script to obtain the titles for websites, it's not that easy actually to get it from every site, been there.

I had a little time waiting for a friend, decided to expand upon this for you.

 

I used a stream context and file_get_contents, like I said could also use curl()

Checking for valid xml

Also grabbed the title,description and keywords, and made it all arrays

 

You can work out any filtering or escaping before the mysql inserts.

 

<?php
//test url http://www.domain.com/sitemap.xml
//test url http://www.phpfreaks.com/sitemap.xml
if(isset($_GET['url']) && $_GET['url'] != ''){
$url = trim($_GET['url']);
@$xml = simplexml_load_file($url);
if($xml===FALSE) {
die('not a valid xml string');
} else {

foreach ($xml->url as $url_list) {
    $urls = $url_list->loc;
    if (substr($urls, 0, 4) != "http") {
$urls = "http://$urls";
}

$context = stream_context_create(array('http' => array('timeout' => 1)));
$str = file_get_contents($urls, 0, $context);

if(!$str){
die("Unable to connect");
}

$tags = get_meta_tags($urls);
preg_match("/<title>(.*)<\/title>/Umis", $str, $title); 
preg_match("/<head>(.*)<\/head>/is", $str, $head);

$title = $title[1];
if($title == ''){
$title = $urls;
}

$description = $tags['description'];
$keywords = $tags['keywords'];

//make it an array each value, json decode used to remove url from being xml object
$urls_array[] = array("url"=>json_decode($urls,TRUE),"title"=>$title,"description"=>$description,"keywords"=>$keywords);

}//end loop

//see the array
//print_r($urls_array);

//display the array
echo "<hr>";
foreach($urls_array as $url_value){
echo "<a href=".$url_value['url'].">".$url_value['title']."</a><br />";
echo $url_value['description']."<br />";
echo $url_value['keywords']."<br />";
echo "<hr>";
}
}
} else {
echo "No xml url inserted";
}
?>

 

It will return an array like this for phpfreaks sitemap

Thank you for helping.

 

I have tired your code and it works for phpfreak.com/sitemap but not for the website I want to try.

 

I dont need the title I just want the URL for these titles.

 

Lets ssay for example http://www.php.net/sitemap.php

 

You know how they have different link eg. Homepage, News Archives ect. I want each of the URL to be printed then I can import that to database.

So for homepage it would be > http://www.php.net/index.php

So you want to get href links from normal pages and also xml pages.

 

I could just respond back saying use DOM , simple_html_dom, or connect to a page and pattern match href links with regex ... , but I'll let you have this link scraper script that I wrote.

 

The code below uses simplexml if is an xml, curl and DOM if it's not to find the urls, most of the code is functions for finding valid urls and fixing relative links.

 

demo of this code:

http://dynainternet.com/test/grab-links.php

 

the site you provided as an example (non xml):

http://dynainternet.com/test/grab-links.php?target=http://www.php.net/sitemap.php

 

and an xml example:

http://dynainternet.com/test/grab-links.php?target=http://www.phpfreaks.com/sitemap.xml
