Given the following xml document:

<root>
  <text>one</text>
  <text>two</text>
</root>

and the following xsl file:

<xsl:transform version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
  <xsl:template match="text[2]">
    <xsl:value-of select="."/>
  </xsl:template>

  <xsl:template match="text()"/>
</xsl:transform>

xsltproc gives no output at all. Changing the <text> tags to <_text> (and the match to "_text[2]") gives 

<?xml version="1.0"?>
two

as I expect. Matching "text[1]" gives

<?xml version="1.0"?>
one
