Node Value null when it should not be

[Doug Lochart]

I am relatively new to XSLT so bare with me if this is an easy question.  I created and I am using a Java Extension that takes a NodeList.  The XML Data for the nodes is of this form:   <Date_Opened>2004/07</Date_Opened>   The extension method signature is this:   public String xslGetOldestAndNewestDates(org.w3c.dom.NodeList nodes)   from xsl I call the method like this   ...  <xsl:with-param name="data" select="java:xslGetOldestAndNewestDates($xslHelper,//Date_Opened)"/>   Which should select all Date_Opened nodes.   In the body of the extension method I iterate over the nodes.  When I call getNodeName() I get the correct name but when I call getNodeValue() I get null.  I read somthing about indeterminate node types returning null so I tried casting it to a Text node and a DTMNodeProxy but I still get Null.  I had another extension function that takes a list of nodes of which I only use the names to make decisions so I tried doing a getNodeValue() there and that also returned null.   What am I doing wrong?   Thanks in Advance   Douglas Lochart     Now I've gained some understanding Of the only world that we see. Things that I once dreamed of Have become reality.   These walls that still surround me Still contain the same old me, Just one more who's searching for A world that ought to be.
