XPath expression for getting nodes based on date

Question

Hello,
using javax.xml.xpath.XPath (Java 5) I want to get only nodes with dates (element pubDate) greater then some provided date. What is the expression for getting, say only first two <item> nodes? Is it at all possible?
Example XML document:
<?xml version="1.0" encoding="utf-8"?>
<rss version="2.0">
     <channel>
          <title>Channel title</title>
          <link>http://www.foo.bar</link>
          <description>Channel description</description>
          <item>
               <title>title 1</title>
               <link>http://foo.bar.org/1</link>
               <author>author 1</author>
               <pubDate>Thu, 15 Jun 2006 13:14:00 GMT</pubDate>
          </item>
          <item>
               <title>title 2</title>
               <link>http://foo.bar.org/2</link>
               <author>author 2</author>
               <pubDate>Thu, 15 Jun 2006 13:11:00 GMT</pubDate>
          </item>
          <item>
               <title>title 3</title>
               <link>http://foo.bar.org/3</link>
               <author>author 3</author>
               <pubDate>Thu, 14 Jun 2006 13:03:00 GMT</pubDate>
          </item>
          <item>
               <title>title 4</title>
               <link>http://foo.bar.org/4</link>
               <author>author 4</author>
               <pubDate>Thu, 13 Jun 2006 12:59:00 GMT</pubDate>
          </item>
     </channel>
</rss>Thanks for any hints!

I would simply assign value to a variable inside package and use the value in the expression. You can also add variable to configuration if you want to pass a value from outside. You can also add another variable to determine whether you need yesterday or
specific date and set expression accordingly so that you expression will look like
(DT_WSTR,30)([User::DateCategory] == "Specific Date"? @[User::Date]:(DT_WSTR, 4) DATEPART( "yyyy", DATEADD( "dd" , -1, GETDATE() ) ) + Right("0"+(DT_WSTR, 2)DATEPART( "mm", DATEADD( "dd" , -1, GETDATE() ) ),2) + Right("0"+(DT_WSTR, 2)DATEPART( "dd", DATEADD( "dd" , -1, GETDATE() ) ) ,2)) +"_*.TXT"
DateCategory variable should be of type string
and Date should of type date
