Quotes behavior when loading CDATA[] from XML

[#1]

I'm not sure what to make of this.  I'm loading a sql string from an xml file and then doing a Qlikview replace on that sql.  Here is the simplified xml:

<item>
        <sql><![CDATA[select 'text' from table]]></sql>
        <filename>filename.txt</filename>
  </item>

Here's my test script:

XML:
LOAD trim(sql) as sql_string,
    replace(filename, '.txt', '') as filename
FROM test.xml (XmlSimple, Table is [dbCallList/item]);

sql_string:
LOAD sql_string as sql resident XML where filename = 'filename';
let vSQL = peek('sql');

trace $(vSQL);

// replace nothing with nothing
let vSQL = replace('$(vSQL)', '', '');

trace $(vSQL);

The output before the replace is:

select 'text' from table

The output after the replace (which should do nothing):

select ''text'' from table

It adds two single quotes on either side of the string, which make it invalid SQL.  Is this weird?  Or am i missing something?

Thanks

Any thoughts on this?  I submitted it just before the weekend maintenance so it might have gotten lost.
