Hi there, I am truly sorry if the question was asked before, I have searched but it either seems it was not asked, or I do not use the right words... I am trying to deal with group node condition in xpath, /ie/ xpath like //div/(descendant::p|descendant::l)[@n='1'] //div/(ns:p|ns:l)[@n='1'] While this seems to be supported in xpath, I cannot find a way to make it work. My hands are a little tied here because I have not that much freedom about the xpath in itself, I need to be able to support a xpath like that, or rather, I can't go with another simpler route like //div/p[@n='1'] or //div/l[@n='1'] //ns:div/ns:p[@n='1'] or //ns:div/ns:l[@n='1'] The weird thing is that the following xpath would work (//tei:l|//tei:p)[@n='1'] But the moment I add something front of it, it breaks. [node for node in xml.xpath("(//tei:l|//tei:p)[@n='1']", namespaces={"tei": " http://www.tei-c.org/ns/1.0"})] Thank you for your time and help Best Thibault
