Adding " " into an XML file

Hi Guys
another nooby question but I just can’t find the answer anywhere. I have a sample player that works fine with a hand coded xml. its form is
<code>
<TextVar>
<theText url=“c:/Files/Texts” />
</TextVar>
</code>
my question is how can I form an xml file in this way, that is to have actual " " passed? I keep getting badly formed errors when I try.
Best
Frederick
