Sitemap.xml is working but Google says missing xml tag (fix inside)

After digging into your code i found a very neat solution!
the problem is: <url> needs to jump to the next line. it was right behind “<urlset>”. Good that you have a hook for that. for everyone having the same problem, just add this code snippet to your functions.php

add_action("sm_build_content",function(){ echo "\n";});

Great fix. Thanks for that!

It definitely needs including in the next release, if possible.

I have exactly the same missing XML tag error message problem, but this didn’t work for me, so, because this one is marked resolved, I’m opening a new one.

maybe you have to insert another value for a new line break. it can be different from server to server. try “\n\r” instead of “\n”.

hi, I have the exact same problem. https://i.imgur.com/uFonD2P.png

so where can i put in your code ?

function twentyten_setup() {

	// This theme styles the visual editor with editor-style.css to match the theme style.
	add_editor_style();

	// Post Format support. You can also use the legacy "gallery" or "asides" (note the plural) categories.
	add_theme_support( 'post-formats', array( 'aside', 'gallery' ) );

	// This theme uses post thumbnails
	add_theme_support( 'post-thumbnails' );

	// Add default posts and comments RSS feed links to head
	add_theme_support( 'automatic-feed-links' );

just put it in your functions.php

above your function twenty_setup()

like this:

add_action(“sm_build_content”,function(){ echo “\n”;});
function twenty_setup(){
…
}

thank you very much.
