Compare Two Parent Tags

Hello.

I have the following XML code:

Code:

<CRCDATA>
    <CRCDATALINE>
        <CRC>SOM2</CRC>
        <PDFPRINT>N</PDFPRINT>
        <CRCSTATERC>G57</CRCSTATERC>
    </CRCDATALINE>
    <CRCDATALINE>
        <CRC>SOM5</CRC>
        <PDFPRINT>Y</PDFPRINT>
        <CRCSTATERC>G57</CRCSTATERC>
    </CRCDATALINE>
</CRCDATA>

I need to print all <CRCSTATERC> where <PDFPRINT>Y and <CRCSTATERC> not equal to the <CRCSTATERC> in a parent tag.

In my XML code this would be "G57" from the second <CRCDATALINE>.

I have the following XSLT code:

Code:

<xsl:for-each select="CRCDATA/CRCDATALINE">
    <xsl:if test="CRCSTATERC!='' and (PDFPRINT='Y' or not(PDFPRINT))">
        <xsl:if test="not(CRCSTATERC[.=parent::*/preceding-sibling::*/CRCSTATERC]) and HERE'S WHERE I'M STUCK!">
            <xsl:value-of select="CRCSTATERC"/>
        </xsl:if>
    </xsl:if>
</xsl:for-each>

I don't know how to code the second test (HERE'S WHERE I'M STUCK!) to see if the same position of <PDFPRINT> (in the first occurrence of <CRCDATALINE>) is Y. If it is Y, then I would not print the second "G57". If it's N, then second "G57" would print. How would I allow <PDFPRINT> to not be present (as in older versions of my XML files)?

Any help will be greatly appreciated!

Thanks,
Rita

Sorry, Rita, I'm having trouble understanding the question.

Perhaps your requirement is:

For a CRCDATALINE, print (something) if (a) PDFPRINT is "Y" or absent, and (b) there is no preceding-sibling CRCDATALINE having (the same value of CRCSTATERC and (PDFPRINT="Y" or absent))

That would be:

Code:

<xsl:for-each select="CRCDATALINE[not(PDFPRINT='N') and
  not(preceding-sibling::CDCDATALINE[not(PDFPRINT='N') and CRCSTATERC=current()/CRCSTATERC])]">...
