Select ancestor Node

Hi All,

I am having trouble selecting a node with xpath. I hope someone can help. Here is my xml sample:

Code:

<Book>
    <Chapter>
        <revNumber>
            <number>03</number>
        </revNumber>
        <RevDate>
            <date>2006-09-12 </date>
        </RevDate>
        <Sec1/>
        <Sec1>
            <Para>
                <Bullet1>
                    <Para id="chg3">Administrator</Para>
                </Bullet1>
            </Para>
            <Title>REVISIONS:</Title>
        </Sec1>
    </Chapter>
</Book>

I want to grab the value of 'Title'. I tried the following to grab the title if the Para ID='chg3':

<xsl:for-each select="//JBU:Para[@id='chg3']">
    <xsl:variable name="sectiontitle" select="../JBU:Title"/>
    <xsl:variable name="oldtext" select="."/>
    <td>
        <xsl:value-of select="$oldtext"/>
    </td>
    <td>
        <xsl:value-of select="$sectiontitle"/>
    </td>
</xsl:for-each>

I do not return a value. However if Para is a direct child of of Sec1, it returns a value.

Thanks for the help.

Try replacing ".." with ancestor::JBU:Sec1

Thank you Michael. I wasn't sure how to apply the Axis.
