XSLT - Using if statement to reference attribute

[bazza4846]

Hi guys, this is probably an easy one for you, I am fairly new to this. I have taken this small chunk of xml from within a larger xml. Within the xslt I want to use an if statement. But not sure of the syntax to get each applicant.

<invprty id="G1" index="applicant1">
<appforename>Peter</appforename>
<appsurname>Micheals</appsurname>
</invprty>

<invprty id="G2" index="applicant2">
<appforename>Sheila</appforename>
<appsurname>Micheals</appsurname>
</invprty>

I know this test the first applicant is not blank then get the name and so on but i want to be able to pick on the index. Is that possible ?
<xsl:if test="invprty/appforename/text()!="">
<Firstname>
<xsl:value-of select="."/>
</Firstname>
</xsl:f>

Very much appreciate any help you can give me.
