Given this XML I'd like to get /a:root/a:row from //jde-control[jde-legacy-id/text() = '123']

this xpath works but I would like to get rid of the /.. at the end:

$doc//jde-control[jde-legacy-id/text() = '123']/..

I tried this: $doc//*[jde-control/jde-legacy-id/text() = '123'] but it did not return anything.

<a:root>
<a:row>
<a:data>
</a:data>
<jde-control>
<jde-legacy-id>123</jde-legacy-id>
</jde-control>
</a:row>
</a:root>

-c

Paths with // are very inefficient, use direct paths

declare namespace a = "urn:some-uri";

declare variable $x :=
<a:root xmlns:a="urn:some-uri">
<a:row>
<a:data/>
<jde-control>
<jde-legacy-id>123</jde-legacy-id>
</jde-control>
</a:row>
</a:root>;

$x/a:row[jde-control/jde-legacy-id=123]

Ok, I will use a direct path. But just for my knowledge how could I get the ancestor through the use of // ?

<a:row>
<a:data/>
<jde-control>
<jde-legacy-id>123</jde-legacy-id>
</jde-control>
</a:row>
</a:root>;

$x//*[jde-control/jde-legacy-id = 123]
