如何将名称空间从lxml树中剥离？

从每个元素删除名称空间前缀的一种可能方法：

def strip_ns_prefix(tree):    #iterate through only element nodes (skip comment node, text node, etc) :    for element in tree.xpath('descendant-or-self::*'):        #if element has prefix...        if element.prefix: #replace element name with its local name element.tag = etree.QName(element).localname    return tree

在xpath中有名称空间检查而不是使用

if

def strip_ns_prefix(tree):    #xpath query for selecting all element nodes in namespace    query = "descendant-or-self::*[namespace-uri()!='']"    #for each element returned by the above xpath query...    for element in tree.xpath(query):        #replace element name with its local name        element.tag = etree.QName(element).localname    return tree
