Find and replace double quote

[Anonymous]

I need to find and and replace double quotes, I have tried
<sx:findAndReplace searchFor="""" replaceWith="&quot;" />
<sx:findAndReplace searchFor='"' replaceWith="&quot;" />
<sx:findAndReplace searchFor='\"' replaceWith="&quot;" />

This would be amazing if you knew how to do this.

I have been reading more and I am still stuck. Right now I cant get findAndReplace to work at all.  First can I use find and replace inside a fieldElementMap, or does it have to be a elementMap? Second I am just trying to replace something simple and it still doesn't work.
<sx:elementMap element="{userdept}">
    <sx:findAndReplace searchFor="8021" replaceWith="&quot;" useRegex="false" >
        <sx:toString value="{userdept}"/>
    </sx:findAndReplace>
</sx:elementMap>
will this work? because its not working for me.
<sx:fieldElementMap field="userdept" element="userdept">
    <sx:findAndReplace searchFor="8021" replaceWith="&quot;" useRegex="false" >
        <sx:toString value="{userdept}"/>
    </sx:findAndReplace>
</sx:fieldElementMap>
