In magento all config.xml files from all modules are merged to a single file at the end.

Is it possible to show the content of that file for debugging purposes?

you can try to print the result of Mage::getConfig()->getNode()->asXML()


I found the solution. I installed n98-magerun

Execute this command:

./n98-magerun.phar config:dump

Please prefer the above method, because it is the safest one. There is a risk that your frontend users can see your output if you are using other methods which are rendering the output in the frontend.

Alternative Method - if you like to only view specific config files e.g. system.xml (or of course config.xml):

header('Content-Type: text/plain');            
echo Mage::getConfig()

Found here.

The loadModulesConfiguration method will look in each configured module’s etc folder for a file with the passed in name (in this case, system.xml). Magento has a number of other configuration files (api.xml, wsdl.xml, wsdl2.xml, convert.xml, compilation.xml, install.xml), and as a module developer you can leverage this functionality to create your own.

  • Is there a similar function in M2 equivalent to this one to get webapi collection as xml? I see way to get di dependency dump but not webapi
