selecting elements from a flat file

Hi, 

I am having problems selecting a group of sibling elements from a flat
file.
The file is of the form...

<main>
        <a name='Title'></a>
        <a></a>
        <a></a>
        <a></a>
        <b></b> 
        <a></a> 
        <a></a>
        <b></b> 
        <a></a> 
</main>

and I need to select all the <a> elements between <a name='Title'> and
the first <b> element.

I am trying to use keys to achieve this using the following XSL.....



<xsl:key name="about_st" match="a"
use="generate-id(preceding-sibling::a[(_at_)name='Title'][1])"/>

<xsl:key name="about_en" match="a"
use="generate-id(following-sibling::b[1])"/>
        
<xsl:template match="main">
<manual>
<about>
        <xsl:apply-templates select="a[(_at_)name='Title']"/>
</about>
</manual>
</xsl:template>

<xsl:template match="a[(_at_)name='Title']">
        <xsl:variable name="genID" select="generate-id()"/>
        <xsl:for-each select="key('about_st', $genID)">
                <xsl:apply-templates select="key('about_en', $genID)"/>
        </xsl:for-each>
</xsl:template>

<xsl:template match="a">
        <xsl:value-of select="."/>
</xsl:template> 



The problem is that the first key selects all the <a> elements following
a name='Title'>
but the second key returns nothing.

Can someone point out where I have gone wrong? Or is there a better way
to do this?
(I am trying to do this without using XSL 2 to avoid having to install
additional software
on the customers machine.)

Many thanks,
