需要从平面文件构建层次结构并建立父子关系

Question

我正在尝试从平面文件开发层次结构，因此我需要在所需的输出中建立父子关系。您能否在XSLT 2.0中建议一种方法。

请在下面找到包含LEVEL和NAME标记的输入XML，在此基础上我试图建立父子关系。

只需添加更多信息，所有带有'I'的NAME标签都应放在单独的标签中，例如LOCATION，而所有带有'L'的NAME标签应放在单独的标签中，例如输出中的ADDRESS。

输入XML：

<Path>
<item>
<LEVEL>1</LEVEL>
<RANK>340</RANK>
<TYPE>T</TYPE>
<DESC>Sheet</DESC>
<NAME>I</NAME>
</item>
<item>
<LEVEL>2</LEVEL>
<RANK/>
<TYPE>M</TYPE>
<DESC>Handler</DESC>
<NAME>D</NAME>
</item>
<item>
<LEVEL>2</LEVEL>
<RANK>341</RANK>
<TYPE>M</TYPE>
<DESC>Sheet</DESC>
<NAME>I</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK/>
<TYPE>M</TYPE>
<DESC>PDF</DESC>
<NAME>D</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>330</RANK>
<TYPE>M</TYPE>
 <DESC>SER </DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>331</RANK>
<TYPE>M</TYPE>
<DESC>SEN</DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>2</LEVEL>
<RANK>342</RANK>
<TYPE>M</TYPE>
 <DESC>xyz</DESC>
<NAME>I</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>335</RANK>
<TYPE>M</TYPE>
<DESC>FIL</DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>2</LEVEL>
<RANK>343</RANK>
<TYPE>M</TYPE>
<DESC>safety </DESC>
<NAME>I</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK/>
<TYPE>M</TYPE>
<DESC>doc</DESC>
<NAME>D</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>337</RANK>
<TYPE>M</TYPE>
 <DESC>ROD </DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>338</RANK>
<TYPE>M</TYPE>
<DESC>CYL</DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>3</LEVEL>
<RANK>339</RANK>
<TYPE>M</TYPE>
<DESC>COMP</DESC>
<NAME>L</NAME>
</item>
<item>
<LEVEL>2</LEVEL>
<RANK>345</RANK>
<TYPE>M</TYPE>
<DESC>Nyl</DESC>
<NAME>I</NAME>
</item>
</Path>

所需的输出：

<Path>

        <LOCATION>
            <LEVEL>1</LEVEL>
            <RANK>340</RANK>

            <DESC>Sheet</DESC>
            <NAME>I</NAME>
