domxpath

The title sums it up. I'm trying to query an HTML file for all div tags that contain the class result and does not contain the class grid . <div class="result grid">skip this div</div> <div class="result">grab this one</div> Thanks! This should do it: <?php $doc = new DOMDocument(); $doc->loadHTMLFile('test.html'); $xpath = new DOMXPath($doc); $nodeList = $xpath->query( "//div[contains(@class, 'result') and not(contains(@class, 'grid'))]"); foreach ($nodeList as $node) { echo $node->nodeName . "\n"; } Your XPath would be //div[contains(concat(' ', @class, ' '), ' result ') and not(contains

I've building a command line php scraping app that uses XPath to analyze the HTML - the problem is every time a new DOMXPath class instance gets loaded in a loop I'm getting a memory loss roughly equal to the size of the XML being loaded. The script runs and runs, slowly building up memory usage until it hits the limit and quits. I've tried forcing garbage collection with gc_collect_cycles() and PHP still isn't getting back memory from old Xpath requests. Indeed the definition of the DOMXPath class doesn't seem to even include a destructor function? So my question is ... is there any way to

Trying to decide which is more appropriate for my use case... After comparing the documentation for these methods, my vague understanding is evaluate returns a typed result but query doesn't. Furthermore, the query example includes looping through many results but the evaluate example assumes a single typed result. Still not much the wiser! Could anyone explain (in as close as possible to layman's terms) when you would use one or the other - e.g. will the multiple/single results mentioned above always be the case? ThW DOMXPath::query() supports only expressions that return a node list.

I am trying to scrap some content from a website but the code below is not working(not showing any output). here is the code $url="some url"; $otherHeaders=""; //here i am using some other headers like content-type,userAgent,etc some curl to get the webpage ... .. curl_setopt($ch,CURLOPT_RETURNTRANSFER,1); $content=curl_exec($ch);curl_close($ch); $page=new DOMDocument(); $xpath=new DOMXPath($page); $content=getXHTML($content); //this is a tidy function to convert bad html to xhtml $page->loadHTML($content); // its okay till here when i echo $page->saveHTML the page is displayed $path1="//body

So I have a HTML string like this: <td class="name"> <a href="/blah/somename23123">Some Name</a> </td> <td class="name"> <a href="/blah/somename28787">Some Name2</a> </td> Using XPath I'm able to get value of href attribute using this Xpath query: $domXpath = new \DOMXPath($this->domPage); $hrefs = $domXpath->query("//td[@class='name']/a/@href"); foreach($hrefs as $href) {...} And It's even easier to get a text value, like this: // Xpath auto. strips any html tags so we are // left with clean text value of a element $domXpath = new \DOMXPath($this->domPage); $names = $domXpath->query("//td[
