我试图遍历一个大型xml文件,并收集一些数据。由于可以通过路径找到数据的位置,所以我使用了xpath,但没有结果。
有人能告诉我我做错了什么吗?
xml示例:
<?xml version="1.0" encoding="UTF-8"?>
<rootnode>
<subnode1>
</subnode1>
<subnode2>
</subnode2>
<subnode3>
<listnode>
<item id="1"><name>test name1</name></item>
<item id="2"><name>test name2</name></item>
<item id="3"><name>test name3</name></item>
</listnode>
</subnode3>
</rootnode>守则:
import lxml.etree as ET
tree = ET.parse('temp/temp.xml')
subtree = tree.xpath('./rootnode/subnode3/listnode')
for next_item in subtree:
Id = next_item.attrib.get('id')
name = next_item.find('name').text
print('{:>20} - {:>20}'.format(name,Id))发布于 2019-10-30 08:58:01
你们很亲密。
Ex:
import lxml.etree as ET
tree = ET.parse('temp/temp.xml')
subtree = tree.xpath('/rootnode/subnode3/listnode')
for next_item in subtree:
for item in next_item.findall('item'):
Id = item.attrib.get('id')
name = item.find('name').text
print('{:>20} - {:>20}'.format(name,Id))或
subtree = tree.xpath('/rootnode/subnode3/listnode/item')
for item in subtree:
Id = item.attrib.get('id')
name = item.find('name').text
print('{:>20} - {:>20}'.format(name,Id)) 输出:
test name1 - 1
test name2 - 2
test name3 - 3https://stackoverflow.com/questions/58621542
