我想解析嵌套元素。我不介意使用XPath或Element。例如,我想要打印的一些值是:
>>> root[0][0][0][0][0].tag
'{http://www.domain.com/somepath/Schema}element'
>>> root[0][0][0][0][0].text
'findme'
迭代XML文档,解析和打印element
值的理想方法是什么?以下是我正在使用的架构示例。
<?xml version="1.0" encoding="UTF-8"?>
<data xsi:schemaLocation="http://www.domain.com/somepath/Schema file.xsd" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.domain.com/somepath/Schema">
<one stuff0="" stuff1="">
<two stuff0="" stuff1="">
<three>
<four stuff0="234234" stuff1="234324">
<element>findme</element>
</four>
<four stuff0="234234" stuff1="234324">
<element>findme2</element>
</four>
<four stuff0="234234" stuff1="234324">
<element>findme3</element>
</four>
</three>
</two>
</one>
<one stuff0="" stuff1="">
<two stuff0="" stuff1="">
<three>
<four stuff0="234234" stuff1="234324">
<element>findme4</element>
</four>
<four stuff0="234234" stuff1="234324">
<element>findme5</element>
</four>
<four stuff0="234234" stuff1="234324">
<element>findme6</element>
</four>
</three>
</two>
</one>
</data>
虽然没有返回任何结果,但我尝试了以下内容。即使这确实有效,也不会看到根1 [0] 1 [0] [0]等下的元素:
>>> for tagname in root[0][0][1][0][0].findall('element'):
... name = tree.get('element')
... print name
...
>>>
根据这个question,我也尝试了以下内容但没有成功:
>>> for elem in doc.findall('one/two/three/four'):
... print value.get('stuff1'), elem.text
...
>>>
发现问题:
由于缺少我在阅读Need Help using XPath in ElementTree后学到的命名空间规范,因此未读取该元素。以下示例有效:
>>> import xml.etree.cElementTree as ET
>>> for event, element in ET.iterparse("schema.xml"):
... if element.tag == "{http://www.domain.com/somepath/Schema}element":
... print element.text
...
findme
findme2
findme3
findme4
findme5
findme6
答案 0 :(得分:0)
如果没有看到您的XML文档,我无法确定,但我认为您想要做的是:
<强>的test.xml 强>
<?xml version="1.0"?>
<root>
<group>
<element>This is the first text</element>
</group>
<group>
<element>This is the second text</element>
</group>
<group>
<element>This is the third text</element>
</group>
</root>
<强> test.py 强>
import xml.etree.cElementTree as ET
for event, element in ET.iterparse("test.xml"):
if element.tag == "element":
print element.text
在我得到的终端中运行这些文件:
mike@tester:~$ python test.py
This is the first text
This is the second text
This is the third text
