未按所需結構出現的分組元素-有解無憂

我嘗試根據 @style 對元素進行分組，所有情況看起來都很好，只是這里的問題是首先 p[@style="TRH7" 沒有在 TRH4 之前關閉。

我在這里參考但沒有運氣。

輸入 XML：

<?xml version="1.0" encoding="UTF-8"?>
<text width="12240" height="15840" orient="">
    <p type="itemlist" id-rel="1" level="1" style="TRH2">
        <r>Test scenario 1 (TRH2) /chapter/title</r>
    </p>
    <p type="itemlist" id-rel="1" level="6" style="TRH7">
        <r>Test Scenario 2 (TRH7) /chapter/section/title</r>
    </p>
    <p style="TRNormal">
        <r>Test Scenario 3 (TRNormal) /chapter/section/paragraph </r>
    </p>
    <table>a</table>
    <p type="itemlist" id-rel="1" level="3" style="TRH4">
        <r>Test Scenario 4 (TRH4) /chapter/division/title</r>
    </p>
    <p type="itemlist" id-rel="1" level="6" style="TRH7">
        <r>Test Scenario 5 (TRH7) /chapter/division/section/title</r>
    </p>
    <p style="TRNormal">
        <r>Test Scenario 6 (TRNormal) /chapter/division/section/paragraph </r>
    </p>
    
    <p type="itemlist" id-rel="1" level="4" style="TRH5">
        <r>Test Scenario 7 (TRH5) /chapter/division/subdivision/title</r>
    </p>
    <p type="itemlist" id-rel="1" level="5" style="TRH6">
        <r>Test Scenario 8 (TRH6) /chapter/division/subdivision/arabicSubdivision/title</r>
    </p>
    <p type="itemlist" id-rel="1" level="6" style="TRH7">
        <r>Test Scenario 9 (TRH7) /chapter/division/subdivision/arabicSubdivision/section/title</r>
    </p>
    <p style="TRNormal">
        <r>Test Scenario 10 (TRNormal)
            /chapter/division/subdivision/arabicSubdivision/section/paragraph </r>
    </p>
    <p style="TRNormal">
        <r>Test 1 </r>
    </p>
    <p style="TRNormal">
        <r>Test 2 </r>
    </p>
