如何扫描日志文件中的XML值并将它们合并到一行中

import xml.etree.ElementTree as ET

def merge_xml_values(log_file):
    merged_values = ""
    
    with open(log_file, 'r') as file:
        for line in file:
            xml_start_index = line.find("<")
            xml_end_index = line.find(">")
            
            if xml_start_index != -1 and xml_end_index != -1:
                xml_string = line[xml_start_index:xml_end_index+1]
                root = ET.fromstring(xml_string)
                
                # 提取XML值的示例：假设XML中有一个名为"value"的元素
                value = root.find("value").text
                
                merged_values += value + " "
    
    return merged_values.strip()

log_file = "example.log"
merged_values = merge_xml_values(log_file)
print(merged_values)
