Wrong HTML parsing assumptions

  • After fixing the Settings page I tried the shortcode and it came up blank. I looked at errors.log and noticed this:

    PHP Warning: simplexml_load_string(): Entity: line 2: parser er
    ror : AttValue: ” or ‘ expected in […]/plugins/h-gallery/h-gallery.php on line 55
    PHP Warning: simplexml_load_string(): <html lang=en> in […]/plugins/h-gallery/h-gallery.php on l
    ine 55
    PHP Warning: simplexml_load_string(): ^ in […]/plugins/h-gallery/h-gallery.php on lin
    e 55
    [ad nauseum]

    This is just wrong. Quotes have never been required in any version of HTML if the attribute value consists solely of letters, digits, and hyphens.
