XPath over more levels - html

Question

is it possible with xpath to extract something in another Level ?
In my table there are diffrent diffrent rows . In one if it there is my row where somewhere is print "bpmtestinstanz". I need to get the URL (href) of the the Link where is "Instanz abbauen" in the Link and in the table-row (tr) "bpmtestinstanz" inside . But I don't know how i should handle xpath over the diffrent levels of the Link and the printed text .
<tr class="htmlobject_tr even" onclick="tr_click(this, 'idp54bf6c72037f1')" onmouseover="tr_hover(this, 'idp54bf6c72037f1')" onmouseout="tr_hover(this, 'idp54bf6c72037f1')">
<td class="htmlobject_td state">
<span class="pill active">
active</span>
</td>
<td class="htmlobject_td config">

Answer 1

It can be done, but it's slightly complicated.
//tr[td[#class = 'htmlobject_td config' and contains(b[contains(., 'Hostname')]
/following-sibling::text()[1],'bpmtestinstanz')]]/td[#class = 'htmlobject_td action']
/a[contains(.,'Instanz abbauen')]/#href
which means
//tr[td[#class = 'htmlobject_td config' Select all `tr` elements anywhere in
the document, but only if they have
at least one `td` child element that
has a `class` attribute with the
value "htmlobject_td config"
and contains(b[contains(., 'Hostname')] and only if this `td` child element
also has a child element `b` whose
text value contains "Hostname"
/following-sibling::text()[1],'bpmtestinstanz')]] and if the first following sibling
of this `b` element which is a text
node contains "bpmtestinstanz"
/td[#class = 'htmlobject_td action'] of this `tr` select a child `td`
element that has a `class` attribute
with the value "htmlobject_td action"
/a[contains(.,'Instanz abbauen')]/#href and select its child `a` if its text
contains "Instanz abbauen" - and
finally select the `href` attribute
of this `a` element.
This solution requires "bpmtestinstanz" to be immediately after <b>Hostname</b>. If it can appear anywhere in the tr element, you can somewhat simplify the expression.
