問題描述

我被這個錯誤卡住了:

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

很明顯一些Xml文件有問題，但我真的不容易在大海撈針中找出針:)

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 :)

對此有什么好的做法嗎?如果可能的話，我想找到一個涉及使用 Xdebug 或一些日志的好習(xí)慣.

Any good practice for that? If possible I would like to find a good practice that involves use Xdebug, or some log.

在 Magento 中經(jīng)常會出現(xiàn)拼寫錯誤.

It happens a lot of time in Magento to do some miss spelling.

推薦答案

我覺得你可以看看這篇文章 處理 XML 錯誤.

I think you can take a look at this article Dealing with XML errors.

此警告與一些 config.xml 錯誤有關(guān)，因此找出確切文件的可能解決方法是修改./lib/Varien/Simplexml/Config.php 類.

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.

你應(yīng)該修改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;
}

如果錯誤與某些布局文件有關(guān)(Update.php line 444 警告)

In case the error is related to some Layout file ( Update.php line 444 warning )

您應(yīng)該以類似的方式修改 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;
}

現(xiàn)在只需重新加載頁面并讀取錯誤信息.

Now just reload the page a read the error info.
