Frequently asked questions

        

                

                    What does XML formatting do?
                    
It adds consistent indentation and line breaks so nested elements are easier to inspect.

                

                

                    What makes XML well formed?
                    
XML needs one root element, properly nested closing tags, quoted attributes, and valid escaping for reserved characters.

                

                

                    Does formatting validate against an XSD?
                    
No. This tool checks XML syntax; schema validation is a separate process that checks document-specific rules.

                

                

                    Will formatting change element values?
                    
The formatter preserves element and attribute data, though insignificant whitespace between elements may be normalized.
