XSLT: How to peek nested element - xslt

Question

That's my xml I need to apply an xslt:
<document>
<component>
<structuredBody>
<component>
<section>
<identifier code="S001"/>
<...>
</section>
</component>
</structuredBody>
</component>
</document>
As you can see, here there's a lot of nested structure I don't need.
What I'm only need is to peek section element where section>identifier.code = "S001".
I'd like to peek my desired element without taking care of upper structure.
I'm using this xslt but it's not peeking my desired section element:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:value-of select="//section[identifier/#code = 'S001']"/>
</xsl:template>
</xsl:stylesheet>
But I'm getting:
<?xml version="1.0" encoding="UTF-8"?>
Above example was a reduced effort to simplify my problem:
<document>
<component>
<structuredBody>
<component>
<section>
<identifier code="S001"/>
<table>
<tbody>
<tr>
<td>attribute1</td>
<td>value1</td>
</tr>
<tr>
<td>attribute2</td>
<td>value2</td>
</tr>
<tr>
<td>attribute3</td>
<td>value3</td>
</tr>
</tbody>
</table>
</section>
<section>
<identifier code="S002"/>
<table>
...
</table>
</section>
</component>
</structuredBody>
</component>
</document>
What I really need is to get something like:
<person> <!-- -> section-->
<attribute key="attribute1">value1</attribute>
<attribute key="attribute2">value2</attribute>
<attribute key="attribute3">value3</attribute>
</person>
Any ideas?

Try:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes"/>
<xsl:template match="/">
<xsl:for-each select="//section[identifier/#code='S001']">
<person>
<xsl:for-each select="//td[1]">
<attribute key="{.}"><xsl:value-of select="../td[2]"/></attribute>
</xsl:for-each>
</person>
</xsl:for-each>
</xsl:template>
</xsl:stylesheet>
