Python 2.7 通过指定限制从xml获取节点

以下是

xml

<Faculty>
    <facultyMember>
        <FirstName>A</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>B</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>C</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>D</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>E</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>F</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>G</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>H</FirstName>
    </facultyMember>

</Faculty>

如何使用

etree python

？

找到所有

facultyMember

项并使用python的列表切片：

from xml.etree import ElementTree as ET


data = """<Faculty>
    <facultyMember>
        <FirstName>A</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>B</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>C</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>D</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>E</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>F</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>G</FirstName>
    </facultyMember>
    <facultyMember>
        <FirstName>H</FirstName>
    </facultyMember>

</Faculty>"""

tree = ET.fromstring(data)
begin, end = 3, 6

for element in tree.findall('.//facultyMember')[begin - 1: end]:
    print ET.tostring(element).strip()

从xml.etree导入ElementTree作为ET
data=”“”
A.
B
C
D
E
F
G
H
"""
tree=ET.fromstring（数据）
开始，结束=3，6
对于tree.findall（'.//facultyMember'）[begin-1:end]中的元素：
打印ET.tostring（元素）.strip（）

印刷品：

<facultyMember>
        <FirstName>C</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>D</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>E</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>F</FirstName>
    </facultyMember>

C
D
E
F

谢谢，但是如果我想使用

列表中的
OrderedDict
格式怎么办？好的，您能提供所需的输出吗？谢谢
<facultyMember>
        <FirstName>C</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>D</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>E</FirstName>
    </facultyMember>
<facultyMember>
        <FirstName>F</FirstName>
    </facultyMember>
