I’m trying to validate the following code (Inside a XHTML transitional doc): 

<a href="#" onclick="document.getElementById('courseFrameBottomRight').innerHTML = '<iframe  src=\'descriptions/bf_isc.html\' scrolling=\'no\' frameborder=\'0\'></iframe>'" id='onClickTextChange2'><span class="title">Website</span></a>

However, this is throwing a huge number of validation errors.

Example:

Line 168, Column 98: character “<” is
the first character of a delimiter but
occurred as data

The code is modified from a help guide and I don’t have experience with the nested quoting or back-slashing going on here. Can someone offer some quick syntax pointers for me to get this valid for
XHTML Transitional? Thanks!

    Try backslashing the ‘<‘ ‘>’ signs, like '\<iframe\>'

    If it doesn’t work use the html code instead:

    &gt; for >
    &lt; for <

    &lt;iframe&gt;

    So the only phrase would be something like:

    <a href="#" onclick="document.getElementById('courseFrameBottomRight').innerHTML = '\<iframe  src=\'descriptions/bf_isc.html\' scrolling=\'no\' frameborder=\'0\'\>\<\/iframe\>'" id='onClickTextChange2'><span class="title">Information Systems Clinic</span></a>

    or 

    <a href="#" onclick="document.getElementById('courseFrameBottomRight').innerHTML = '&lt;iframe  src=\'descriptions/bf_isc.html\' scrolling=\'no\' frameborder=\'0\'&gt;&lt;/iframe&gt;'" id='onClickTextChange2'><span class="title">Information Systems Clinic</span></a>

    Or better yet, create a javascript function that does what you need outside the html body code.
