TiddlyWiki sees any content inside angle brackets as HTML syntax, which it passes to the browser for processing.
Thus, in your example, <set xpath="...">30000</set>, only the 30000 remains to be rendered by TiddlyWiki.
You can bypass this handling by enclosing the content within single backtick characters, like this:
`<set xpath="/items/item/property[@name='Stacknumber']/@value">30000</set>`
This will tell TiddlyWiki to render the content as <code>...</code>, which prevents the browser from processing the angle-bracket enclosed content. Note that, by default, TiddlyWiki formats "code" content using red monospaced text on a gray background with a border. If you want to change this appearance so the content looks like normal text, you can create a tiddler, tagged with $:/tags/Stylesheet, containing the following CSS rule:
.myCode code { color:inherit; background:inherit; border:0; font-family:inherit; }
Then, you can enclose your table content within like this:
@@.myCode
|`<set xpath="/items/item/property[@name='Stacknumber']/@value">30000</set>` |Description goes here |
|`another command here` |Another description here |
@@
By doing this, any <code>...</code> within the table will appear as normal, unparsed text. Q.E.D
