Need Help With Position of Current Node From Root

ritagr · August 2nd, 2012, 06:27 PM

Hello.

I need to get the position of the current node in relation to the root "/" of the XML document.

Code:

<doc>
    <EOB>
        <DETAIL>
            <DETAILLINE>
                <RCDATA>
                    <RCDATALINE>
                        <TRC>AAAAAAAAA1</TRC>
                    </RCDATALINE>
                    <RCDATALINE>
                        <TRC/>
                    </RCDATALINE>
                </RCDATA>
                <CRCDATA>
                    <CRCDATALINE>
                        <CRCFUNCTION>800</CRCFUNCTION>
                    </CRCDATALINE>
                    <CRCDATALINE>
                        <CRCFUNCTION/>
                    </CRCDATALINE>
                </CRCDATA>
            </DETAILLINE>
            <DETAILLINE>
                <RCDATA>
                    <RCDATALINE>
                        <TRC>WWWWWWWW1</TRC>
                    </RCDATALINE>
                    <RCDATALINE>
                        <TRC/>
                    </RCDATALINE>
                </RCDATA>
                <CRCDATA>
                    <CRCDATALINE>
                        <CRCFUNCTION>900</CRCFUNCTION>
                    </CRCDATALINE>
                    <CRCDATALINE>
                        <CRCFUNCTION/>
                    </CRCDATALINE>
                </CRCDATA>
            </DETAILLINE>
        </DETAIL>
    </EOB>
</doc>

So if my current node is <CRCFUNCTION>800</CRCFUNCTION>, I need to figure out that the position() is 15 (counting back to the /doc element).

I tried this:
xsl:number value="position()" format="1. " level="multiple"/> but the value was 1.

Thanks in advance!

Sorry, i can't see where your expected answer of 15 comes from. If I count preceding elements, I get 11. If I count all preceding nodes including whitespace text nodes I get 26.

I see two possible ways of getting 15. Perhaps it's the line number of the node, or perhaps it's the number of preceding tags (counting both start and end tags).

You need to explain your requirement better.

Thanks for your response Michael.

I was thinking about my problem last night.
It's basically very simple. I need to check all the occurrences of <CRCFUNCTION> for a value not = '900' in any of the occurrences. The problem is that <CRCFUNCTION> can be = '' (empty) which satisfies the test of not = '900'.

So I need to test for <CRCFUNCTION> not ='900' and that exact node also not be empty. I thought if I could get the node number starting from root I could use that in the second part of the test where I check for "and != '' ".

The <CRCFUNCTION> can have values of 600, 700, 800, 900 or empty.
What I'm trying to accomplish is call a template if any <CRCFUNCTION> is equal to 600, 700 or 800.

Thanks,
Rita

I can't see how this question relates to your previous question, where you were trying to determine the "position" of a node without saying exacly what you mean by "position".

Finding the node whose position you are interested in seems to be a completely separate question.

You can find the CRCFUNCTION nodes with a value of 600, 700, or 800 using either

Code:

CRCFUNCTION[. = ('600', '700', '800')]

or

Code:

CRCFUNCTION[not(. = ('900', ''))]

whichever you prefer.

Thank you Michael for all your help - much appreciated.

This question does not really relate to my previous question - I just had a couple of thoughts as to how to resolve my issue.

Your response made it so simple.
