xml - PHP: createTextNode as object -


i have script reads xml tags , prints on page. items links (without html tags) made function adds html link tags it. however, links rendered strings , not html.

i know because used createtextnode, need returns object , not string.

heres code

function get_feeds() {     $feeds = array(         array(             'name' => 'agenda',             'url' => 'http://www.beleefdokkum.nl//pages/rss.aspx?type=agenda',             'get' => array('title', 'description', 'link'),             'scope' => array(1, 10)         ),         array(             'name' => 'news',             'url' => 'http://www.beleefdokkum.nl//pages/rss.aspx?type=nieuws',             'get' => array('title', 'description', 'link'),             'scope' => array(1, 10)         ),         array(             'name' => 'social media',             'url' => 'http://api.twitter.com/1/statuses/user_timeline.rss?screen_name=nofriesland',             'get' => array('description'),             'scope' => array(1, 10)         )     );      $result = new domdocument();      function linkify($text) {         $text = preg_replace('/(https?:\/\/\s+)/', '<a href="\1" class="preg-links">\1</a>', $text);         $text = preg_replace('/(^|\s)@(\w+)/', '\1@<a href="http://twitter.com/\2" class="preg-links">\2</a>', $text);         $text = preg_replace('/(^|\s)#(\w+)/', '\1#<a href="http://search.twitter.com/search?q=%23\2" class="preg-links">\2</a>', $text);         return $text;     }      foreach ($feeds $feed) {         $xml = new domdocument();         $xml->load($feed['url']);         $frame = $result->createelement('div');         $frame->setattribute('class', 'feed_frame');         $result->appendchild($frame);         $name = $result->createelement('h1', $feed['name']);         $name->setattribute('class', 'feed_name');         $frame->appendchild($name);         $content = $result->createelement('div');         $content->setattribute('class', 'feed_content');         $frame->appendchild($content);         ($i = $feed['scope'][0]; $i < $feed['scope'][1]; $i++) {             $item = $result->createelement('span');             $item->setattribute('class', 'feed_item');             $content->appendchild($item);             foreach ($feed['get'] $get) {                 $object = $result->createelement('p');                 $text = $result->createtextnode(linkify($xml->getelementsbytagname($get)->item($i)->nodevalue));                 $object->appendchild($text);                 $object->setattribute('class', 'feed_'.$get);                 $item->appendchild($object);             }         }     }     return $result->savehtml(); }

there might other ways, solve creating both text nodes , anchors you're performing regular expression matching:

$node = $dom->createelement('p'); linkify($doc, $node, 't1 @test t2 #test t3 http://www.stackoverflow.com t4');

the linkify() function takes existing node , creates text nodes , anchors based on given string.

function linkify($dom, $node, $text) {     // combine possible patterns in 1 expression     $re = '/(https?:\/\/\s+)|(?:^|\s)@(\w+)|(?:^|\s)#(\w+)/';     // capture pattern offsets     $flags = preg_set_order | preg_offset_capture;      $offset = 0;     if (preg_match_all($re, $text, $matches, $flags)) {         foreach ($matches $match) {             // set start , end markers of matched pattern             $start = $match[0][1];             $end = $match[0][1] + strlen($match[0][0]);             // process each pattern based on resulting matches             if (isset($match[3])) { // twitter hash                 $start += 2; // skip space , #                 $url = 'http://search.twitter.com/search?q=' .                      urlencode("#{$match[3][0]}");                 $anchor = anchor($dom, $url, $match[3][0]);             } elseif (isset($match[2])) { // twitter user                 $start += 2;                 $url = 'http://twitter.com/' . urlencode($match[2][0]);                 $anchor = anchor($dom, $url, $match[2][0]);             } else { // standard url                 $anchor = anchor($dom, $match[1][0], $match[1][0]);             }              if ($start > $offset) {                 // have text in between previous match (or start) , here                 $str = substr($text, $offset, $start - $offset);                 $node->appendchild($dom->createtextnode($str));             }             // insert new anchor             $node->appendchild($anchor);             // keep track of last match marker             $offset = $end;         }         // add last text node         $node->appendchild($dom->createtextnode(substr($text, $offset)));     } }

this output when run ->savehtml():

<p>   t1     @<a href="http://twitter.com/datibbaw" class="preg-links">datibbaw</a>    t2    #<a href="http://search.twitter.com/search?q=%23test" class="preg-links">test</a>   t3     <a href="http://www.stackoverflow.com" class="preg-links">http://www.stackoverflow.com</a>    t4</p>

i'm using convenience function create anchors:

function anchor($dom, $url, $text) {     $anchor = $dom->createelement('a', $text);     $anchor->setattribute('href', $url);     $anchor->setattribute('class', 'preg-links');      return $anchor; }

Why does Ruby on Rails generate add a blank line to the end of a file? -

running rails generate controller foo home results in: class foocontroller < application controller def home end end (there's nothing on line in actual file, blank line) is there purpose blank line? it's common use newline indicate end of line, last line. many editors (like vi, use) add in newline silently. consensus text files (especially in unix world) should end in newline, , there have been problems historically if wasn't present. why should text files end newline? the tool used count lines in file "wc" counts newlines in file, without trailing newline show 3 instead of 4. it improves readability of templates used in generator. consider: https://github.com/rails/rails/blob/master/railties/lib/rails/generators/rails/controller/templates/controller.rb to remove trailing newline, template have last line of: end<% end -%> instead of: end <% end -%> that seems less readable me. the discussion below refers ...
