Difference between select="./node()" and select="node()" in DSpace's item-view.xsl

Question

Inside of statements that select a dim:field in DSpace's item-view.xsl, I find

<xsl:copy-of select="node()"/>

in context:

<xsl:for-each select="dim:field[@element='description' and @qualifier='abstract']">
   <xsl:choose>
      <xsl:when test="node()">
         <xsl:copy-of select="node()"/>
      </xsl:when>

as well as

<xsl:copy-of select="./node()"/>

in context:

<xsl:for-each select="dim:field[@element='identifier' and @qualifier='uri']">
   <a>
      <xsl:attribute name="href">
         <xsl:copy-of select="./node()"/>
      </xsl:attribute>

and I wonder if there is any difference between node() and ./node() in this setting, and if so, what difference?

Answer 1

No, there is no difference.

See https://msdn.microsoft.com/en-us/library/ms256086(v=vs.110).aspx

The expressions ./node and node are equivalent.
