私はいくつかの非常に「深い」XMLを持っており（たとえば下部を参照）、minidomまたはelementtreeのいずれかを使用して必要な値に到達するのに苦労しています-太字の値（VALUE_TO_GET）に到達する最も簡単な方法が与えられているアイデアLowestOfferListingタグの数が異なるということですか？私は基本的にそれぞれのLandedPrice/の最初のインスタンスを取得する必要があり、そうするための簡単な（っぽい）方法を見つけることができません！AmountSKUIdentifier

まず、xmlは有効ではないようです。これは、でエラーが発生するelemntreeためです。そこで試してみましたがlxml.html、より堅牢xpathですが、同じままです。

import lxml.html as lh
doc=lh.fromstring(xml)
doc.xpath('//sellersku/text()|//product/descendant::amount[1]/text()')

出力：

['**VALUE_TO_GET**',
 '**VALUE_TO_GET**',
 '**VALUE_TO_GET**',
 '**VALUE_TO_GET**']
