Making Sure XML and HTML Documents Are Valid and Entity Escaped

There are many rules for XML documents and HTML files. While most internet browsers are forgiving, most sitemap validators are not.

This includes when submitting XML Sitemaps to Google. When building HTML and XML sitemap files, it is desired behavior that A1 Sitemap Generator entity escapes and convert the following characters when they occur in URLs, titles, descriptions etc:

  • & into &
  • < into &lt;
  • > into &gt;

Depending on the sitemap file type, this usually also includes:
  • " into &quot;
  • ' into &apos;

By doing this, all HTML Validators, XML Validators, internet browsers etc. can correctly parse URLs when you submit/view sitemap files.

Notes:
  • When viewing XML sitemap files in internet browsers, they will usually show &amp; as the & ampersand character. To see the actual code of generated XML sitemaps, use text editor tools or view source in your internet browser.
  • You should not copy and paste URLs with converted & to &amp; into your internet browser address field. That will normally not work.
