Python 使用etree查找xml中的节点值

下面是

xml

<organizations>
    <organization>
        <orgID>152</orgID>
        <orgName>This is A</orgName>
    </organization>
<organization>
        <orgID>1352</orgID>
        <orgName>This is B</orgName>
    </organization>
    <organization>
        <orgID>1522</orgID>
        <orgName>This is C</orgName>
    </organization>
    <organization>
        <orgID>1512</orgID>
        <orgName>This is D</orgName>
    </organization>
</organizations>

但没有任何指纹

我在这里做错了什么？

一个选项是检查后代的文本：

from lxml import etree as ET


data = """<organizations>
    <organization>
        <orgID>152</orgID>
        <orgName>This is A</orgName>
    </organization>
<organization>
        <orgID>1352</orgID>
        <orgName>This is B</orgName>
    </organization>
    <organization>
        <orgID>1522</orgID>
        <orgName>This is C</orgName>
    </organization>
    <organization>
        <orgID>1512</orgID>
        <orgName>This is D</orgName>
    </organization>
</organizations>"""

tree = ET.fromstring(data)
print tree.xpath('//organization[descendant::text()="1512"]/orgName/text()')

如果我使用问题中提供的内容作为

xmldata

，它会打印如下内容：

也许你应该检查url是否真的提供了内容

顺便说一句，如果要打印

orgName

的文本，请将

for

语句更改如下：

for target in root.xpath('.//organization/orgID[text()="152"]/following-sibling::orgName/text()'):
    print target

['This is D']

for target in root.xpath('.//organization/orgID[text()="152"]/following-sibling::orgName/text()'):
    print target
