Date filtering with XPath

[wha___]

Hello, I need to search through a large XML doc which holds many entries. All entries have a time. I'd like to be able to get this time w/ out physically pulling out the time info, running a strtotime on it and then comparing the seconds. is there a way to shape an XPath-> query or XPath->eval call to acheive this

XML looks like the following
[FONT=courier new]
<entry number=*><info>info</info><time>MM-dd-YY HH:MM:SS</time></entry>
...
[/FONT]

there are a lot of these entry nodes, too many to do the aforementioned method. i think the best way to do this is by massaging eval or query of XPath. Thanks in advance for your help.

Well the XPath specification is at http://www.w3.org/tr/xpath and lists the string-handling functions and predicate syntax you'd use. There's the EXSLT project building various function libraries.
