[xsl] XPTY0004: A sequence of more than one item is not allowed as the second argument of concat()

2010-08-09 09:05:07
Hi All,
I am getting the following error message when trying to transform a 
worldcup.xml 
using worldcup.xsl stylesheet: 

 Error on line 166 
  XPTY0004: A sequence of more than one item is not allowed as the second 
argument of concat()
  at xsl:for-each (#165) processing /html/body[1]/div[2]/p[11]/a[1]

SEVERE: null
; SystemID: ; Line#: 166; Column#: -1
net.sf.saxon.trans.XPathException: A sequence of more than one item is not 
allowed as the second argument of concat()

Below is the worldcup.xsl:


<xsl:template match="/">
  <worldcup>
    <xsl:apply-templates 
select="document(concat(Spain.xml)/ns:html/ns:body/ns:div[(_at_)id='content']">
    </xsl:apply-templates>
  </worldcup>
</xsl:template>
<xsl:template match="/ns:html/ns:body/ns:div[(_at_)id='content']">
    <xsl:variable name="worldcup-team" select="//ns:p[ns:strong='World Cup 
Team:']"/>
    <xsl:apply-templates select="$ worldcup-team"/>
    <xsl:if test="empty($worldcup-team)">
      <team>Unknown</team>
    </xsl:if>
<xsl:template match="ns:p[ns:strong=''World Cup Team:']">
  <xsl:for-each select="ns:a">
      <team><xsl:value-of 
select="concat(./normalize-space(),./following-sibling::text()[normalize-space()])"/></team>

  </xsl:for-each>
</xsl:template>
<xsl:template match="ns:p"/>
</xsl:stylesheet>
 
The snippet of worldcup.xml are as follows:

<html xmlns="http://www.w3.org/1999/xhtml" ; 
xmlns:html="http://www.w3.org/1999/xhtml"; >
<head>
  ……
</head>
<body onload="loadMapLocation(-46.1240, 149.543, 49, 1); setClockTime(2008, 01, 
19, 12, 36, 01); setInterval('updateTime()', 2000);"  onunload="GUnload();" >
<a shape="rect"  name="top" />
<div id="content" >
<hr/>
<h1>World Cup Competition</h1>
<p>
</p>
<p>
<strong>World Cup Team:</strong>
<br clear="none" />
<a shape="rect"  href="http://www.abc.com/team/spain.html?aid=427231"; 
Spain</a> 

 (30 goals)
<br clear="none" />
<a shape="rect"  href=" www.abc.com/team/denmark.html?aid=427231" >Denmark</a>
 (25 goals)
<br clear="none" />
<a shape="rect"  href=" www.abc.com/team/Germany.html?aid=427231" >Germany</a>
 (22 goals)
<br clear="none" />
<a shape="rect"  href=" www.abc.com/team/england.html?aid=427231" >United 
Kingdom</a>
 (15 goals)
<br clear="none" />
……
</p>
<p>
</p>
</div>
</body>
 
 
The desire output would be:

 <team>Spain(30 goals)<team>
 <team>Denmark(25 goals)<team>
 <team>Germany(22 goals)<team>
 <team>United Kingdom (15 goals)<team>


Worldcup.xsl has been successful in transforming worldcup.xml, if it was loaded 
as a main document in the past.

I am using JDOM and Saxon 9.1 to carry out the transformation on Windows XP.
 
Thanks in advance,

Jack
