Looks like now I am trying to use the tokenize function, but it appears that it does not allow me to use id() with it.

You are misinterpreting the evidence.

When I ran the XSLT, it tells me this: F Cannot select a node here: the context item is an atomic value, with the errors pointing to the line where it says id(.).

Exactly. The value of "." is a string. The id() function works on the ID table created for a given tree. When you do not supply a second argument to id(), the tree assumed is that of the current node. There is no tree associated with an atomic value. You need to supply a second argument with a node in the tree from which you wish to draw your ID values.

Here is my XML:

                  <to_do xml:id="cheese">Cheddar Cheese</to_do>
                  <to_do xml:id="beef">Chuck Steak</to_do>
                  <to_do xml:id="vegetables">Brocoli, Beans, Carrots</to_do>
                  <to_do xml:id="milk">Dean's Low Fat Milk 2%</to_do>

 <list>milk cheese vegetables beef</list>

Okay, I'm assuming both of the above are in the same file and not separate files.

Current XSL:

 <xsl:template name="do_list">
  <xsl:variable name="do" select="list">
  <xsl:variable name="item" select="tokenize($item, '\s+')"/>
   <xsl:for-each select="$item">
  <xsl:value-of select="id(.)"/>

Some of the above is just wrong ... you cannot base a variable on a variable of the same name.

I'm assuming you want:

    <xsl:variable name="do" select="list"/>
    <xsl:variable name="item" select="tokenize($do, '\s+')"/>
    <xsl:for-each select="$item">
      <xsl:value-of select="id(.,$do)"/>

I hope this helps.
