问题 I am using Xpath in PHP - I know that my query will return either 0 or 1 results. If 1 result is returned I do not want it as an array - which is what is returned right now. I simply want the value without having to access the [0] element of the result and cast to a string. Is this possible? 回答1: Using 'evaluate' instead of 'query' , you can do things like casting. DOMXPath::evaluate() Also, if you're just annoyed with doing stuff a lot of times, just write a function that does it ... that is

问题 I have an XML file that is approximately 12mb which has about 16000 product's. I need to process it into a database; however, at about 6000 rows it dies with a 500 error. I'm using the Kohana framework (version 3) just in case that has anything to do with it. Here's my code that I have inside the controller: $xml = new XMLReader(); $xml->open("path/to/file.xml"); $doc = new DOMDocument; // Skip ahead to the first <product> while ($xml->read() && $xml->name !== 'product'); // Loop through

问题 I'm trying to parse some HTML that includes some HTML entities, like × $str = '<a href="http://example.com/"> A × B</a>'; $dom = new DomDocument; $dom -> substituteEntities = false; $dom ->loadHTML($str); $link = $dom ->getElementsByTagName('a') -> item(0); $fullname = $link -> nodeValue; $href = $link -> getAttribute('href'); echo " fullname: $fullname \n href: $href\n"; but DomDocument substitutes the text for for A × B. Is there some way to keep it from taking the & for an html entity and

问题 Using PHP I'm attempting to take an HTML string passed from a WYSIWYG editor and replace the children of an element inside of a preloaded HTML document with the new HTML. So far I'm loading the document identifying the element I want to change by ID but the process to convert an HTML to something that can be placed inside a DOMElement is eluding me. libxml_use_internal_errors(true); $doc = new DOMDocument(); $doc->loadHTML($html); $element = $doc->getElementById($item_id); if(isset($element))

问题 For exemple, i create a DOMDocument like that : <?php $implementation = new DOMImplementation(); $dtd = $implementation->createDocumentType ( 'html', // qualifiedName '-//W3C//DTD XHTML 1.0 Transitional//EN', // publicId 'http://www.w3.org/TR/xhtml1/DTD/xhtml1-' .'transitional.dtd' // systemId ); $document = $implementation->createDocument('', '', $dtd); $elementHtml = $document->createElement('html'); $elementHead = $document->createElement('head'); $elementBody = $document->createElement(

问题 In my code, I see this: if (document.getElementById('xx') !=null) { //do stuff } if xx element is not defined, will this evaluate to true or false? Should I write: if (document.getElementById('xx')) to be safe? 回答1: console.log(document.getElementById('xx') ) evaluates to null. document.getElementById('xx') !=null evaluates to false You should use document.getElementById('xx') !== null as it is a stronger equality check. 回答2: getElementById is defined by DOM Level 1 HTML to return null in the
