ElementTree中的xmlns

问题描述

是否可以忽略 elementtree.ElementTree 中的年龄名称中的XML名称空间?

Is there a way to ignore the XML namespace in tage names in elementtree.ElementTree?

我尝试打印所有 technicalContact 标签:

for item in root.getiterator(tag='{http://www.example.com}technicalContact'):
        print item.tag, item.text

我得到类似的东西:

{http://www.example.com}technicalContact [email protected]

但我真正想要的是:

technicalContact [email protected]

是否有办法仅显示后缀(没有xmlns),或者更好-在元素上进行迭代而不显式声明xmlns?

Is there a way to display only the suffix (sans xmlns), or better - iterate over the elements without explicitly stating xmlns?

推荐答案

您可以定义一个生成器以递归地搜索元素树,以找到以适当标签名称结尾的标签。例如,如下所示:

You can define a generator to recursively search through your element tree in order to find tags which end with the appropriate tag name. For example, something like this:

def get_element_by_tag(element, tag):
    if element.tag.endswith(tag):
        yield element
    for child in element:
        for g in get_element_by_tag(child, tag):
            yield g

这只是检查以 tag 结尾的标签,即忽略任何领先的命名空间。然后,您可以迭代所需的任何标签,如下所示:

This just checks for tags which end with tag, i.e. ignoring any leading namespace. You can then iterate over any tag you want as follows:

for item in get_element_by_tag(elemettree, 'technicalContact'):
    ...

此生成器正在运行:

>>> xml_str = """<root xmlns="http://www.example.com">
... <technicalContact>Test1</technicalContact>
... <technicalContact>Test2</technicalContact>
... </root>
... """

xml_etree = etree.fromstring(xml_str)

>>> for item in get_element_by_tag(xml_etree, 'technicalContact')
...     print item.tag, item.text
...
{http://www.example.com}technicalContact Test1
{http://www.example.com}technicalContact Test2
