If I'm manipulating a dom object, is there a way to change the tag name? I know you manipulate just about everything else in a node - but is the tagName really off limits? from the documentation for DOMElement - /* Properties */ readonly public bool $schemaTypeInfo ; readonly public string $tagName ; so if I really needed to change it, I'd have to create a virgin node with the new name, identical attributes and children, and replace the existing node with the new one? Is there any other way to alter the tagName without doing all that?

If this is related to your earlier post about attributes, is XSLT not an option? I hate to sound like a broken record, but PHP has support for XSL transformations and it sounds like that is exactly what you are trying to do. Andrew

No. XSLT is certainly one of the technologies I'm going to look into, but right now I'm building a filter that (hopefully) will fully implement the Mozilla developer Content Security Policy server side before the document gets sent to the browser - by removing what would violate the specified CSP before it is sent. My primary interest in changing tag names is to ensure all tags are lower case so I can then run the rest of the filter. They are all lower case if you use loadHTML() but I don't want my class to assume it has a properly created DOMDocument to start with, so I want to walk the DOM and change bad tags/attribute names before I apply the CSP filtering. That might be something where XSLT is better but I believe I need to install some libraries and recompile php before I can use XSLT as it appears my current build doesn't support it (according to phpinfo()) so playing with XSLT is for another day.
