This short XSLT script converts an XML tree structure into an HTML table that uses @rowspan values to "nest" descendants to the right.
Example input:
<root val="root">
<a val="123">
<b val="xyz">
<c val="456"/>
<c val="789"/>
</b>
<b val="abc">
<c val="def">
<d val="mno"/>
<d val="pqr"/>
</c>
</b>
</a>
<a val="321">
<b val="654">
<c val="987"/>
<c val="ghi"/>
<c val="jkl"/>
</b>
</a>
</root>Corresponding output:
| root | 123 | xyz | 456 |
| 789 | |||
| abc | def | mno | |
| pqr | |||
| 321 | 654 | 987 | |
| ghi | |||
| jkl |
