php - Simple HTML DOM returning NULL -


i'm scraping data website using simple html dom parser (http://simplehtmldom.sourceforge.net/)

the html is:

<tr class="productlisting-odd">     <td align="right" class="productlisting-data">&nbsp;0&nbsp;</td>     <td class="productlisting-data">&nbsp;<a href="http://www.spellvault.net/p46563/liliana-of-the-veil/product_info.html" onmouseout="hd()" onmouseover="sd('images/101257121.jpg')">liliana of veil</a>&nbsp;<br>    </td>     <td align="center" class="productlisting-data">&nbsp;black&nbsp;</td>     <td align="center" class="productlisting-data">&nbsp;mythic&nbsp;</td>     <td align="center" class="productlisting-data">&nbsp;innistrad&nbsp;</td>     <td align="right" class="productlisting-data">€42,50&nbsp;</td>     <td align="center" class="productlisting-data"><input type="text" name="var[46563]" value="" size="4">&nbsp;    <span class="nowrap"><span class="template-button-left">&nbsp;</span><span class="template-button-middle"><input class="submitbutton" type="submit" value="bestel"></span><span class="template-button-right">&nbsp;</span></span>&nbsp;</td>   </tr>

and php:

include_once('simple_html_dom.php');  $html = file_get_html('-the url of search query on website-');  $array = array(); foreach($html->find('.productlisting-odd, .productlisting-even') $element) {     $row = array(         'name' => strip_tags($element->childnodes(1)->innertext),         'set' => strip_tags($element->childnodes(4)->innertext),         'price' => strip_tags($element->childnodes(5)->innertext),         'stock' => strip_tags($element->childnodes(0)->innertext)     );     array_push($array, $row); } echo json_encode($array);

for reason, value of 'price' keeps returning null. other values collected properly. can't figure out why happening, since elements seem have same structure.

thanks in advance!

most html parsed has non-unicode charset. , problem since json_encode() works utf-8 encoding. data parsed has ascii characters doesn't lead problem. price data (6th column) contains non-ascii character '€' on json_encode() fails (and return null).

java - IntelliJ - No such instance method -

using intellij's 12 ultimate, i'm running following code in debugger: java import play.api.libs.json.jsvalue; public class foo { ... public jsvalue tojson() { ... } public class fooexample { ... foo foo = new foo(); system.out.println("...); //<-- breakpoint at breakpoint, right-clicked source code , picked "evaluate expression," typing in: foo.tojson() . but following error showed up: no such instance method: play.api.libs.json.jsvalue$class.com.foo.foo.tojson () am doing wrong? foo#tojson calls scala code, if matters. edit had breakpoint after instantiation of foo. downvoted it, deserved it. edit my answer no longer valid after op modified question (i.e. moved breakpoint actual is).. a breakpoint hit before line executed. in case foo has not yet been declared or instantiated (i.e. foo constructor has not yet been called). you'll need put breakpoint @ next line (or step on current line) if want evaluate foo .

identifier - Is it possible for an html5 document to have two ids? -

i wondering if html5 element can have 2 ids, this: <button id="thing1" id="thing2" name="button1" onclick="change()">click here</button> or this: <button id="thing1, thing2" name="button1" onclick="change()">click here</button> also, if 1 of ids said 1 thing, , other id said thing, 1 used? tl;dr : no. in versions of html, each element can have 1 id. see the spec : the id attribute specifies element's unique identifier (id). [dom] the value must unique amongst ids in element's home subtree , must contain @ least 1 character. the value must not contain space characters. note: there no other restrictions on form id can take; in particular, ids can consist of digits, start digit, start underscore, consist of punctuation , etc. note: element's unique identifier can used variety of purposes, notably way link specific parts of document usin
