我能依靠的是“标签” “Xml发送给引擎”
我正在尝试将正确的C＃/ RegEx转换为
1. Identity the correct line via the tag.
and
2. Get the xml at the end of the line.
我试过这个，但无法弄清楚正则表达式的语法。
string line = string.Empty;

编辑：
我正在使用......通过Joel的回复：
regExPattern = @"(?<tag>\bProcess Xml Sent to XCEProducer.cProducer\b)(?<xmlFragment>\s+(.*)$)";
答案 0 :(得分：2)
如果XML是lefton在该标记之后排列的唯一内容，那么只需执行
regExPattern = @"(?<tag>\bXml Sent to Engine\b)\s+(.*)$"
