在python中不使用换行符解析XML

这是xml文件

我的python代码：

from lxml import etree
def lxml():
    tree = etree.parse('feed.xml')
    NSMAP = {"nn":"http://www.w3.org/2005/Atom"}
    test = tree.xpath('//nn:category[@term="html"]/..',namespaces=NSMAP)
    for elem in tree.iter():
        print(elem.tag,'\t',elem.attrib)
    print('-------------------------------')
    test1 = tree.xpath('//nn:category',namespaces=NSMAP)
    print('++++++++++++++++++++++++++++++++')
    for node in test1:
        test2 = node.xpath('./../nn:summary',namespaces=NSMAP) # return a list
        print(test2.xpath('normalize-space(.)'))
    print('*****************************************')
    test3 = tree.xpath('//text()[normalize-space(.)]')# [normalize-space()] only remove the heading and tailing
    print(test3)

输出为：

++++++++++++++++++++++++++++++++

我的问题是为什么有这么多“\n”。如何删除它们

另外一个问题是如何直接查询文本的标记，例如make以获取“Mark”（条目文本的子项）的节点

非常感谢

“我的问题是为什么有这么多'\n'。如何删除它们？”

XML中的每个空格都将由XPath选择。格式良好的XML通常包含大量的换行符和空格。例如，在下面的XML中，有两个空文本节点将由

//text（）选择

即一个介于

和

之间，另一个介于

和

之间：

<root>
    <foo>bar</foo>
</root>

---

上面应该获取变量

您的\u text\u节点所引用的文本节点的父元素，然后返回元素的标记名。
\n
是一个转义序列

您可以检查页面源代码，发现
膨胀的
位于新行的开头

若要删除它们，您可以使用或。
请不要将代码作为图像发布。将其作为文本发布，并正确设置格式（突出显示/选择文本->单击
{}
）。谢谢我修复了它。很抱歉，因为我是初学者，所以样式不好。谢谢
