解决方法

如果file.xml包含问题中的XML代码段，则此脚本：

from lxml import etree
root = etree.parse(r'file.xml')

for g in root.xpath('.//VariantGroup'):
    name = g.find('.//Name/Value[@locale="en"]')
    desc = g.find('.//Description/Value[@locale="en"]')
    sed = g.find('.//VariantGroupVersion/SaleEffectiveDate[@value]')
    sexd = g.find('.//VariantGroupVersion/SaleExpirationDate[@value]')
    r = g.find('.//RecommendationRank//RecommendationRank[@value]')
    variants = g.findall('.//SPS//Value[@locale="en"]')
    print('Name of Device -',name.text)
    print('Description -',desc.get('value') if desc is not None else None)
    print('SaleEffectiveDate -',sed.get('value') if sed is not None else None)
    print('SaleExpirationDate -',sexd.get('value') if sexd is not None else None)
    print('RecommendationRank -',r.get('value') if r is not None else None)
    print('Included SPS (Variants) -',[v.text for v in variants])
    print('-' * 80)
