Description

Transforming this XML:

<A>
<B>1</B>
<B>2</B>
</A>

with the following XSL:

<xsl:variable name="XML" select="/A"/>

<xsl:template match="/">
First:
<xsl:value-of select="count($XML[B=1])"/>
Second:
<xsl:value-of select="count($XML[B=1])"/>
Third:
<xsl:value-of select="count($XML[B=1])"/>
</xsl:template>

the output is:

First:
1
Second:
2
Third:
3

instead of:

First:
1
Second:
1
Third:
1

Using XALAN 2.6 everithing works as it should be.

Using:

xalan.jar org.apache.xalan.xslt.Process -in %1 -xsl %2 -out %3

instead of:

transformer.transform(xml, xsl)

the result is the right one!
