[xsl] Repeating text in table headers with dynamic values from child node

[Pankaj Yadav <yadavpankaj@xxxxxxxxx>]

Dear All,

I am using FOP version fop-0.20.5rc2 for generating PDF files on
Windows XP box.

I am facing a problem in repeating values in table header
from chid node. To explain this in detail, I am enclosing a sample xml,
required output and xsl I have written for that.


I have following XML
structure which needs to be displayed in a tabular format. 
The number of rows
to be displayed in table is dynamic and 
would depend on number of
StudentResultStruc in XML. 

If the table spans next page, the table headers
need to repeated on next page. 

The XML layout is fixed and cannot be changed
<ExamReport>
    <ClassData>
        <Class>I</Class>
<StudentResultStruc>
            <DateOfTest>01/02/2006</DateOfTest>
<TestNumber>T1</TestNumber>
            <StudentID>A1</StudentID>
<GradeSub1>S1</GradeSub1>
            <GradeSub2>S2</GradeSub2>
<Result>R1</Result>
        </StudentResultStruc>
        <StudentResultStruc>
<TestNumber>T2</TestNumber>
            <StudentID>B1</StudentID>
<GradeSub1>R1</GradeSub1>
            <GradeSub2>R2</GradeSub2>
<Result>P1</Result>
        </StudentResultStruc>
        <StudentResultStruc>
<TestNumber>T3</TestNumber>
            <StudentID>C1</StudentID>
<GradeSub1>G1</GradeSub1>
            <GradeSub2>G2</GradeSub2>
<Result>H1</Result>
        </StudentResultStruc>
        <StudentResultStruc>
<DateOfTest>01/03/2007</DateOfTest>
            <TestNumber>T4</TestNumber>
<StudentID>D1</StudentID>
            <GradeSub1>E1</GradeSub1>
<GradeSub2>E2</GradeSub2>
            <Result>K1</Result>
</StudentResultStruc>
    <ClassData>
<ExamReport>

The output table is as
follows:

--------------------------  Page 1
----------------------------------------
Date of Test(s)     01/02/2006
Test
Number   Student ID   Grade Sub 1   Grade Sub 2   Result
T1            A1
S1            S2            R1
T2            B1           R1            R2
P1

If this table spans on next page then, the Date of Test and 
Table header
need to repeat on next page as follows:

--------------------------  Page 2
----------------------------------------
Date of Test(s)     01/02/2006
Test
Number   Student ID   Grade Sub 1   Grade Sub 2   Result
T3            C1
G1            G2            H1

---------------------------- on Change of
Date, the headers need to appear again.

Date of Test(s)     01/03/2007
Test
Number   Student ID   Grade Sub 1   Grade Sub 2   Result
T4            D1
E1            E2            K1

appreciated.
