Accessing sub node using E4X

Hey all - I'm trying to access a sub node in my xml without success, any pointers would be great!!

Code:

---

    XML -

              <book>
                      <title>a title</title>
                      <author>an author</author>
                      <price>a price</price>
                      <photos>
                                  <photo>
                                              <url>URL</url>
                                              <width></width>
                                              <height></height>
                                  </photo>
                        <photos>
              </book>

Ok this is just a sample xml I knocked up as my actual is quite large, but the idea is the same. I am using

Code:

---

        var valueRange = xmlData.valueRange; // finds a specific node group called 'valueRange' from the large loaded xml in xmlData.
        for (var i:uint = 0; i < valueRange.children().length(); i++) {
              trace ("item is string? = " + valueRange.*[i] is String+"\n");
                  trace("item " + i + " = " + valueRange.*[i].text()+"\n");
            }

---

which pulls out the title, author, price data, but the sub nodes are just item n =

It reports that the sub nodes are Strings. Any suggestions would be great!!
