    How do I make & a literal character in an XML parse?

    Hey Folks,

    ....and here I thought I was done with my AJAX application.

    The XML my PHP app is returning to my JavaScript function has elements in
    it that contain special characters... specifically the ampersand & which
    hoses up the data. ex: Company Name = "K & B Construction".

    Can anyone give me some idea of how I make the data coming out of my
    database translate as literal characters in the XML output?

    -thx

      Simply by applying the htmlentities or htmlspecialchar s function.

          I think you should deal with this at the PHP side because '&' is
          reserved for the declaration of entities. The best way is to encode
          your special chars to html entities before adding them to the XML file.
          I'ld say that PHP should have ready-to-go regexes for this kind of
          things.

          If necessary, you could add !ENTITY !DOCTYPE !ELEMENT headers etc, but
          don't rely too much on parser-specific implementations . You'll do
          yourself a big favour with that :-)

              There is, htmlentities().
              Unfortunately, it doesn't recognize every character, and coverts the
              ampersand in already converted entitities. In the comments, someone claims
              to have written a better function for it:
              404 Not Found
              http://www.prolifique.com/entities.php.txt


              I haven't tried the code yet, maybe it's usefull here.

              Grtz,

                  <snip>

                  Not sure, if you need CDATA.

                      I just parsed them into &amp; and it works fine. Thanks.
