我有以下节点，我在流读取器中检索。可能有很多这些。我只想检索此节点中的几个组，例如REPLICATE_ID, ASSAY_NUMBER,FEW DATES FIELDS。
节点内字段的顺序可能不同，有时也会出现新字段，但我想要提取的字段不会改变。
到目前为止，我所使用的正则表达式匹配整个节点，因此如果节点有新字段或顺序不同，它会中断。是否有可能匹配我感兴趣的群组？

是的，您可能只需解析键值对的记录。
如果要从记录中提取键值对，可以使用以下代码示例 找到匹配项后，可以针对捕获集合中的那些键测试您要查找的键。
您还可以更改正则表达式，了解如何允许记录的开始/结束 但是不要改变核心，它可以防止灾难性的回溯。
正则表达式替代方案：
# Record starts on a new line, closing brace can be anywhere
^ [^\S\n]*TEST_REPLICATE\s*\{
(?>
\s* (?<key> [^\s{}]+ ) [^\S\n]* (?<val> [^\n{}]*? ) [^\S\n]* (?:$|(?=\}))
)*
\s*\}
# Record starts anywhere, closing brace is on a new line
TEST_REPLICATE\s*\{
(?>
\s* (?<key> [^\s{}]+ ) [^\S\n]* (?<val> [^\n{}]*? ) [^\S\n]* $
)*
\s*\}
C＃测试代码：
Regex testRx = new Regex(
@"
^ [^\S\n]* TEST_REPLICATE # Record, starts on a newline
\s* # Optional whitespaces (trims blank lines)
\{ # Record opening brace
(?> # Atomic group
\s* # Optional many whitespace (trims blank lines)
# Line in record to be recorded
(?<key> [^\s{}]+) # required <key>, not whitespacs nor braces
[^\S\n]* # trim whitespaces (don't include newline)
(?<val> [^\n{}]*?) # optional <value>, not newlines nor braces
[^\S\n]* # trim whitespaces (don't include newline)
(?:$|(?=\})) # End of line, or next char is a closing brace
)* # End atomic group, do many times (optional)
\s* # Optional whitespaces (trims blank lines)
\} # Record closing brace
", RegexOptions.IgnorePatternWhitespace | RegexOptions.Multiline);
