[4suite] More unexplained behavior of 4XLST

[Bob Myers]

Hi.  I am having no luck getting the <xsl:value-of> element to work.  (I am
using version 0.9.0 of 4Suite, downloaded and installed a couple of days
ago.)

% cat bug.xsl
<?xml version="1.0"?>
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
               version="1.0">

<xsl:template match="at">
  <xsl:text><xsl:value-of select="@x"/></xsl:text>
</xsl:template>

</xsl:transform>

% cat bug.xml
<?xml version="1.0"?>
<doc>
<at x='1' y='2'/>
</doc>

%4xslt bug.xsl bug.xml
Traceback (innermost last):

    value = self.firstChild.data
AttributeError: data

It seems like all other variations of the value for the "select" attribute
also fair, including ones such as "position()".

I am probably missing something very basic, but any help would be
appreciated.

Whatever is causing the above bug is apparently also causing a bug in the
use of the <xsl:number> instruction.

PS.  This is part of an application I am developing to represent the
Japanese game of go in xml, and the style sheet above is a fragment of one
to convert such a game into an SVG graphic.  Such a graphic (created by
other means) is attached for your amusement.

Thanks in advance.
