我有一个文件,我想从中解析特定值。如何将以下所有三个正则表达式放在一起为每个测试返回一组条目,无论它是否有测量值以及它是否有错误,并且如果有的话,包括测量值和错误?一个测试中可以有任意数量的测试、任意数量的度量,但在没有其他度量的测试中只有一个错误。我尝试了许多不同的组合,但都没有成功。我想我需要使用前瞻和交替,但没有找到正确的组合。仅供参考,正则表达式存储在数据库中并由 C# 应用程序使用。提前致谢!

为了解析测试部分,我使用了正则表达式,它有效:
\<teststart\sstartid\s=\s"
(?<tid>.*?)"\>
.*\n
.*\<test\>
(?<testid>.*?)\<
.*\n
.*\<test_start_time\>
(?<teststartdate>.*?)T
(?<teststarttime>.*?)\</.*\n
.*?
\<exe\>
(?<texe>.*?)\<.*\n
(.*?\n)*?
.*?\<testend.*?\n
.*?\<test_result\>
(?<result>.*?)\<.*\n
.*?duration_units="
(?<dunits>.{1}).*?
\>
(?<duration>.*?)\<
为了解析测量数据,我使用了正则表达式,它有效:
.*?\<measurement\smeasid\s=\s"
(?<measid>.*?)"\>.*\r\n
(.*?\r\n)*?
.*?
\<measurement_name\>
(?<measurename>.*?)\<.*\r\n
.*?
\<numeric_measurement\>
(?<measurenum>[^/s].*?)\<.*\r\n
.*?
\<measurement_time\>
(?<measureDate>[^/s].*?)T
(?<measureTime>[^/s].*?)\<.*\r\n
要解析错误,我使用正则表达式,它有效:
.*?\<measurement\smeasid\s=\s"
(?<measid>.*?)"\>.*\r\n
.*?\<measurement_name\>
(?<measurename>.*?)\<.*\r\n
.*?\<error_code\>
(?<sterrcode>.*?)\<.*\r\n
.*?\<error_message\>
(?<sterrmsg>.*?)\<.*\r\n
.*?\<measurement_time\>
(?<measureDate>[^/s].*?)T
(?<measureTime>[^/s].*?)\<.*\r\n
.*?\<measurement_result\>
(?<measureResult>[^/s].*?)\<.*\r\n
免责声明:是的,我知道输入是 XML,但我无法将应用程序更改为反序列化,它使用正则表达式。
