问题描述
我被这个错误卡住了:
Warning: simplexml_load_string(): Entity: line 46: parser error : Comment not terminated in */lib/Varien/Simplexml/Config.php on line 510
和
Entity: line 46: parser error : Start tag expected, '<' not found in */lib/Varien/Simplexml/Config.php on line 510
很明显一些Xml文件有问题,但我真的不容易在大海捞针中找出针:)
It is clear that there is an issue in some Xml file, but really not easy for me to find out the needle in the big haystack :)
对此有什么好的做法吗?如果可能的话,我想找到一个涉及使用 Xdebug 或一些日志的好习惯.
Any good practice for that? If possible I would like to find a good practice that involves use Xdebug, or some log.
在 Magento 中经常会出现拼写错误.
It happens a lot of time in Magento to do some miss spelling.
推荐答案
我觉得你可以看看这篇文章 处理 XML 错误.
I think you can take a look at this article Dealing with XML errors.
此警告与一些 config.xml 错误有关,因此找出确切文件的可能解决方法是修改./lib/Varien/Simplexml/Config.php 类.
This warning is related to some config.xml error, so a possible workaround to find out the exact file is to mod. the /lib/Varien/Simplexml/Config.php class.
你应该修改Varien_Simplexml_Config::loadString()方法:
public function loadString($string) { if (is_string($string)) { // Enable internal errors libxml_use_internal_errors(true); $xml = simplexml_load_string($string, $this->_elementClass); if (false === $xml) { // Put breakpoint here $errors = libxml_get_errors(); } if ($xml instanceof Varien_Simplexml_Element) { $this->_xml = $xml; return true; } } else { Mage::logException(new Exception('"$string" parameter for simplexml_load_string is not a string')); } return false; }
如果错误与某些布局文件有关(Update.php line 444 警告)
In case the error is related to some Layout file ( Update.php line 444 warning )
您应该以类似的方式修改 Mage_Core_Model_Layout_Update::getFileLayoutUpdatesXml() 方法:
You should modify Mage_Core_Model_Layout_Update::getFileLayoutUpdatesXml() method in a similar way:
public function getFileLayoutUpdatesXml($area, $package, $theme, $storeId = null) { if (null === $storeId) { $storeId = Mage::app()->getStore()->getId(); } /* @var $design Mage_Core_Model_Design_Package */ $design = Mage::getSingleton('core/design_package'); $layoutXml = null; $elementClass = $this->getElementClass(); $updatesRoot = Mage::app()->getConfig()->getNode($area.'/layout/updates'); Mage::dispatchEvent('core_layout_update_updates_get_after', array('updates' => $updatesRoot)); $updateFiles = array(); foreach ($updatesRoot->children() as $updateNode) { if ($updateNode->file) { $module = $updateNode->getAttribute('module'); if ($module && Mage::getStoreConfigFlag('advanced/modules_disable_output/' . $module, $storeId)) { continue; } $updateFiles[] = (string)$updateNode->file; } } // custom local layout updates file - load always last $updateFiles[] = 'local.xml'; $layoutStr = ''; foreach ($updateFiles as $file) { $filename = $design->getLayoutFilename($file, array( '_area' => $area, '_package' => $package, '_theme' => $theme )); if (!is_readable($filename)) { continue; } $fileStr = file_get_contents($filename); $fileStr = str_replace($this->_subst['from'], $this->_subst['to'], $fileStr); libxml_use_internal_errors(true); $fileXml = simplexml_load_string($fileStr, $elementClass); if (false === $fileXml) { // Put breakpoint here $errors = libxml_get_errors(); $err = array($filename, $errors); // error detail and file name will be printed Zend_Debug::dump($err); die(); } if (!$fileXml instanceof SimpleXMLElement) { continue; } $layoutStr .= $fileXml->innerXml(); } $layoutXml = simplexml_load_string('<layouts>'.$layoutStr.'</layouts>', $elementClass); return $layoutXml; }
现在只需重新加载页面并读取错误信息.
Now just reload the page a read the error info.
