I've just encountered a very strange problem, illustrated below.
Source XML
<Records>
<Record>
<id>1</id>
</Record>
<Record>
<id>2</id>
</Record>
</Records>
XSL:
<xsl:variable name="id" select="'2'" />
<xsl:for-each select="/Records/Record">
[<xsl:value-of select="id=$id" /> (<xsl:value-of select="id"
/>|<xsl:value-of select="$id" />)]
</xsl:for-each>
<xsl:for-each select="/Records/Record">
[<xsl:value-of select="id=number($id)" /> (<xsl:value-of
select="id" />|<xsl:value-of select="$id" />)]
</xsl:for-each>
Output:
[true (279|279)] [true (301|279)] <!-- ?!?!!?! -->
[true (279|279)] [false (301|279)] <!-- this is what i'd expect -->
What's going on?
