To Remove only specified parent element not child element in xslt

Input xml like below.

<part type="frontmatter">
<section level="1"><title>THIEME Atlas of Anatomy</title>
........
</section>
<section level="1">
<title></title><para><emph type="bold">To access additional material
......
</section>
</part>
<part type="content">
<section level="1">
<title id="p001">Structure and Development of Organ Systems</title>
...
<section level="2">
<title>Suggested Readings</title>
.......
</section>
</section>
</part>

Output should be

<part type="frontmatter">
<section level="1"><title>THIEME Atlas of Anatomy</title>
........
</section>
<section level="1">
<title></title><para><emph type="bold">To access additional material
......
</section>
</part>
<part type="content">
<title id="p001">Structure and Development of Organ Systems</title>
...
<section level="2">
<title>Suggested Readings</title>
........
</section>
</part>

My xslt is:

<xsl:template match="section[position()=1]"><!-\-//-\->
    <xsl:if test="preceding-sibling::part[@type='content'][not(title)]">
        <part type="content">
        <xsl:apply-templates select="node() | @*"/>
        </part>
    </xsl:if>
</xsl:template>

I want to remove <section level="1"> element which is appearing under <part type="content"> where "title" element should not appear between these two elements. If "title" is appear under part element then should not make any change.

If you want to remove section element, under a part element, where there is no preceding title, then the template match should look like this

<xsl:template match="part[@type='content']/section[@level='1'][not(preceding-sibling::title)]">

Try this XSLT

<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output method="xml" />

    <xsl:template match="part[@type='content']/section[@level='1'][not(preceding-sibling::title)]">
        <xsl:apply-templates />
    </xsl:template>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>
</xsl:stylesheet>

Note, in this particular example, you may be able to simplify it to this

<xsl:template match="part[@type='content']/section[1]">

So, just remove the section element if it is the first child element of part. This would not work if you could have elements other that title preceding the section.
