python '<a>x</a><a111>x1</a111>'转成字典
时间: 2023-10-30 11:07:26 浏览: 39
可以使用Python内置的`xmltodict`库将XML格式的字符串转换为字典。具体操作如下:
```python
import xmltodict
xml_str = "<root><a>x</a><a111>x1</a111></root>"
xml_dict = xmltodict.parse(xml_str)
print(xml_dict)
```
输出结果为:
```
{'root': {'a': 'x', 'a111': 'x1'}}
```
其中,`xmltodict.parse()`函数将XML字符串解析成字典格式。解析后的字典中,XML标签名作为键,标签内容作为值。如果标签内还有子标签,子标签名和内容也会被作为键值对存储在字典中。

你可以使用Python中的xml.etree.ElementTree库来解析XML数据并提取标签中的有效数据。以下是一个示例代码,演示如何提取出有效数据:
```python
import xml.etree.ElementTree as ET
# 定义XML字符串
xml_string = '''

运行这段代码,它将解析XML字符串并提取出标签中的有效数据。你可以根据需要对提取出的数据进行进一步处理或存储。

root = ET.fromstring(xml_str)
# 定义正则表达式
pattern = re.compile(r'<(\w+)>\*\*\*</\w+>')
# 遍历xml节点
for elem in root.iter():
matches = pattern.findall(ET.tostring(elem).decode())
if matches:
print(elem.tag + " contains: " + matches[0])
```
输出结果为:
```
area contains: ***
detailAddress contains: ***
mobile contains: ***
name contains: ***
oaid contains: ***
tel contains: ***
```
可以看到,这些带*号的内容分别位于receiverInfo和senderInfo子节点下的不同字段中。
