XSLT: repetitive nodes in the output

I'm struggling with a simple xsl transformation and I'm not able to find out why I have two elements twice in my output result. Here is my code:

xsl-stylesheet: 

<xsl:template match="/">
    <xsl:text>[{</xsl:text> 
    <xsl:apply-templates/>
    <xsl:text>}]</xsl:text> 
</xsl:template>

<xsl:template match="Title">
    <xsl:text>{</xsl:text>        
    <xsl:value-of select="@id"/>     
    <xsl:apply-templates select="descendant::Title"/>            
    <xsl:text>}</xsl:text>    
</xsl:template>

xml:

<?xml version="1.0" encoding="UTF-8"?>
<Start>
    <Title id="1">
        <Title id="2">Bob</Title>
        <Age>39</Age>
        <Address>
            <Title id="3">10 Idle Lane</Title>
            <City>Yucksville</City>
            <PostalCode>xxxyyy</PostalCode>
        </Address>
    </Title>
    <Title id="4">
        <Title id="5">Bill</Title>
        <Age>39</Age>
        <Title id ="6">
            <Title id="7">10 Idle Lane</Title>
            <City>Yucksville</City>
            <PostalCode>xxxyyy</PostalCode>
            <Title id="8">10 Idle Lane</Title>
        </Title>
        <Title id="9">10 Idle Lane</Title>
    </Title>    
</Start>

output:

[{
    {1{2}{3}}
    {4{5}{6{7}{8}}{7}{8}{9}}    
}]

The elements which I've not expected to have in my output are the last numbers: {8}{9}. I guess it has something to do with the descendant axis selector.

True, the descendant axis selector selects all children and grandchildren etc.. So you just need to apply templates to children. This should work:

<xsl:template match="/">
    <xsl:text>[{</xsl:text>
    <xsl:apply-templates/>
    <xsl:text>}]</xsl:text>
</xsl:template>

<xsl:template match="Title">
    <xsl:text>{</xsl:text>
    <xsl:value-of select="@id"/>
    <xsl:apply-templates />
    <xsl:text>}</xsl:text>
</xsl:template>

<xsl:template match="text()" />
