XSLT - To move parent attribute value into child first para - xslt

Question

Input is like as,
<section counter="yes" level="5">
<title><target id="page92"/></title>
<section counter="yes" level="6">
<title>Standard 12-lead ECG at Rest</title>
<para>The standard ECG is recorded at rest using 12 leads in order to collect as much information as possible:</para>
<listing type="dash">
<litem><para>Standard limb leads according to Einthoven (I, II, III)</para></litem>
Output should be,
<section counter="yes" level="5">
<title><target /></title>
<section counter="yes" level="6">
<title>Standard 12-lead ECG at Rest</title>
<para id="page92">The standard ECG is recorded at rest using 12 leads in order to collect as much information as possible:</para>
<listing type="dash">
<litem><para>Standard limb leads according to Einthoven (I, II, III)</para></litem>
We wrote xslt as shown below,
<xsl:template match="para[1][parent::section[parent::section[not(normalize-space(title))]]]">
<xsl:choose>
<xsl:when test="position() = 1">
<para>
<xsl:attribute name="id" select="ancestor::section[not(normalize-space(title))]/title/target/#id"/>
<xsl:apply-templates select="#*"/>
<xsl:apply-templates/>
</para>
</xsl:when>
<xsl:otherwise>
<para>
<xsl:apply-templates select="#*|node()"/>
</para>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
While using above xslt, we are unable to meet expected output.
<section counter="yes" level="5">
<title><target /></title>
<section counter="yes" level="6">
<title>Standard 12-lead ECG at Rest</title>
<para id="page92">The standard ECG is recorded at rest using 12 leads in order to collect as much information as possible:</para>
<listing type="dash">
<litem><para id="page92">Standard limb leads according to Einthoven (I, II, III)</para></litem>
The "page ID" value is repeating on following paragraphs which we didn't required. We need to maintain the page ID only on 1st paragraph.
Could you please guide us.

As for getting the result you want, it should be as simple as
<xsl:transform xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="2.0">
<xsl:template match="#*|node()">
<xsl:copy>
<xsl:apply-templates select="#*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="section[not(normalize-space(title))]/section/para[1]">
<xsl:copy>
<xsl:attribute name="id" select="ancestor::section[not(normalize-space(title))]/title/target/#id"/>
<xsl:apply-templates select="#*"/>
<xsl:apply-templates/>
</xsl:copy>
</xsl:template>
<xsl:template match="section/title[not(normalize-space())]/target/#id"/>
</xsl:transform>
