html - php remove tags before a specified tag -


i want remove image-tags before headline starts, not nested same way. , remove empty tags.

<div class="c2">   <img src="image/file" width="480" height="360" alt="image" /> </div> <div class="c2">   <div class="headline">     headline   </div>   <div class="headline">     headline2   </div> </div>

and different nested tags like

<div class="c2">   <p>     <img src="image/a.jpg" width="480" height="319" alt="image" />   </p>   <div class="headline">     headline   </div> </div>

i think solved recursively, dont know how.

thanks help!

edit: if want remove <img> followed <div><div class="headline>" or <div class="headline">, use xpath:

$imgs = $xpath->query("//img[../following-sibling::div[1]/div/@class='headline' or ../following-sibling::div[1]/@class='headline']");

see working: http://codepad.viper-7.com/qhprlp

do this:

$doc = new domdocument(); $doc->loadhtml($x); // assuming html in $x $xpath = new domxpath($doc); $imgs = $xpath->query("//img"); // select <img> nodes  foreach ($imgs $img) { // loop through list of <img> nodes $parent = $img->parentnode;  $parent->removechild($img); // delete <img> node if ($parent->childnodes->length >= 1) // if parent node of <img> empty delete         $parent->parentnode->removechild($parent); }  echo htmlentities($doc->savehtml()); // display new html

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
