Default Compare Two Parent Tags


I have the following XML code:
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:
<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"/>
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!

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:

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