I don't see a way you could do this with a single XPath expression.
This works with your example, though:

1 <xsl:template match="/">
2   <xsl:apply-templates select="data/value[@attr = 'second']"/>
3 </xsl:template>
5 <xsl:template match="value">
6   <xsl:number count="value" from="/data"/>
7 </xsl:template>

Presumably your actual data is more complex than what you are
showing us, so you might need to use a modal template to prevent
outputting the position of every value element:

2   <xsl:apply-templates select="data/value[@attr = 'second']" mode="get-position"/>

5 <xsl:template match="value" mode="get-position">
