I think this could be simple to solve with XSLT 2.0. Below is the
working stylesheet:

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                       version="2.0">

<xsl:output method="xml" indent="yes" />

<xsl:template match="/">
  <result>
    <xsl:apply-templates select="//*[@name][not(@name = 'root')]" />
  </result>
</xsl:template>

<xsl:template match="*">
  <fullName>
    <xsl:value-of select="string-join(ancestor-or-self::*[not(@name =
'root')]/@name,'.')" />
  </fullName>
</xsl:template>

</xsl:stylesheet>

This when applied to the given XML, produces output:

<?xml version="1.0" encoding="UTF-8"?>
<result>
   <fullName>a1</fullName>
   <fullName>a1.a2</fullName>
   <fullName>a1.a2.a3</fullName>
   <fullName>b1</fullName>
   <fullName>b1.b2</fullName>
</result>
