How to select the XML node with the longest child value #text node with XPath?

I used XPath to select the node with the largest integer id value before using this query:

//somenode[not(@id <= preceding::somenode/@id) and not(@id <= following::somenode/@id)]

I was hoping I could do something like this:

//entry[not(string-length(child::text()) <= string-length(preceding::entry/child::text())) and not(string-length(child::text()) <= string-length(following::entry/child::text()))]

But it returns a bunch of nodes instead of one.

XML example:

<xml>
  <entry>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</entry>
  <entry>Nam dignissim mi a massa mattis rutrum eu eget mauris.</entry>
  <entry>Ut at diam a sem scelerisque pretium nec pulvinar purus.</entry>
  <entry>Nunc in nisi nec dolor accumsan suscipit vel a quam.</entry>
  <entry>Nunc suscipit lobortis arcu, nec adipiscing libero bibendum nec.</entry>
  <entry>Aenean eget ipsum et nunc eleifend scelerisque.</entry>
  <entry>In eu magna et diam volutpat molestie.</entry>
  <entry>In volutpat luctus mi, eu laoreet orci dictum vel.</entry>
  <entry>In mattis mi nec magna sodales eu bibendum felis aliquet.</entry>
<!-- etc for 800 more lines or so -->
  <entry>Duis auctor felis id neque gravida ut auctor ipsum ullamcorper.</entry>
  <entry>Sed vel tortor mauris, et aliquet tellus.</entry>
</xml>

XPath 1.0, XPath 1.0 (string-length(someNodeSet) node node -set). , XPath 1.0 .

XPath 2.0 :

/*/entry[not(string-length(.) &lt; /*/entry/string-length(.))]

entry , .

/*/entry[not(string-length(.) &lt; /*/entry/string-length(.))] [1]

( ) entry.

XSLT 2.0:

:

<xsl:stylesheet version="2.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:template match="/">
  <xsl:sequence select=
   "/*/entry[not(string-length(.) &lt; /*/entry/string-length(.))]"/>
 </xsl:template>
</xsl:stylesheet>

XML-:

<xml>
  <entry>Lorem ipsum dolor sit amet, consectetur adipiscing elit.</entry>
  <entry>Nam dignissim mi a massa mattis rutrum eu eget mauris.</entry>
  <entry>Ut at diam a sem scelerisque pretium nec pulvinar purus.</entry>
  <entry>Nunc in nisi nec dolor accumsan suscipit vel a quam.</entry>
  <entry>Nunc suscipit lobortis arcu, nec adipiscing libero bibendum nec.</entry>
  <entry>Aenean eget ipsum et nunc eleifend scelerisque.</entry>
  <entry>In eu magna et diam volutpat molestie.</entry>
  <entry>In volutpat luctus mi, eu laoreet orci dictum vel.</entry>
  <entry>In mattis mi nec magna sodales eu bibendum felis aliquet.</entry>
<!-- etc for 800 more lines or so -->
  <entry>Duis auctor felis id neque gravida ut auctor ipsum ullamcorper.</entry>
  <entry>Sed vel tortor mauris, et aliquet tellus.</entry>
</xml>

entry ( ) :

<entry>Nunc suscipit lobortis arcu, nec adipiscing libero bibendum nec.</entry>
