Magento : find out which xml fails

If you’ve been working with Magento extensions or layout, you might have encountered the frustration of trying to find out which XML generates the following error, potentially harming the whole magento installation :

01	Warning: simplexml_load_string() [function.simplexml-load-string]: Entity: line 61: parser error : StartTag: invalid element name  in C:\aa_work\RueDeSiam\www\lib\Varien\Simplexml\Config.php on line 502

the problem with this kind of error is that it doesn’t tell you which file is causing the error. To find out, work with your local installation

• set the developer mode in index.php : Mage::setIsDeveloperMode(true);
• open the app/code/core/Mage/Adminhtml/Model/Config.php and let the _initSectionsAndTabs tell you which xml is being loaded in the modules loop, just after $configFile is defined : echo $configFile;
• the last file that pops before the error is thrown out is likely to cause the breakout !
