Answer 2

谢谢楼上两位回答。现在问题来了，我同事说在
string html = @"s=oEditor.CreateBox(
[
    ""NAME:BoxParameters"",
    ""XPosition:=""     , ""-1.4mm"",
    ""YPosition:=""     , ""1.4mm"",
    ""ZPosition:=""     , ""0mm"",
    ""XSize:=""     , ""0.6mm"",
    ""YSize:=""     , ""1.4mm"",
    ""ZSize:=""     , ""-0.6mm""
], 
[
    ""NAME:Attributes"",
    ""Name:=""     , ""Box1"",
    ""Flags:=""     , """",
    ""Color:=""     , ""(132 132 193)"",
    ""Transparency:=""    , 0,
    ""PartCoordinateSystem:="", ""Global"",
    ""UDMId:=""     , """",
    ""MaterialValue:=""    , ""\""vacuum\"""",
    ""SolveInside:=""     , True
])

Answer 3

对于如下字符串
string html = @"s=oEditor.CreateBox(
[
    ""NAME:BoxParameters"",
    ""XPosition:=""     , ""-1.4mm"",
    ""YPosition:=""     , ""1.4mm"",
    ""ZPosition:=""     , ""0mm"",
    ""XSize:=""     , ""0.6mm"",
    ""YSize:=""     , ""1.4mm"",
    ""ZSize:=""     , ""-0.6mm""
], 
[
    ""NAME:Attributes"",
    ""Name:=""     , ""Box1"",
    ""Flags:=""     , """",
    ""Color:=""     , ""(132 132 193)"",
    ""Transparency:=""    , 0,
    ""PartCoordinateSystem:="", ""Global"",
    ""UDMId:=""     , """",
    ""MaterialValue:=""    , ""\""vacuum\"""",
    ""SolveInside:=""     , True
])
我需要把里面的XPosition等属性及对应的数值给读出来。
我可以通过如下匹配项
oEditor.CreateBox\(
\s*\[
\s*"NAME:BoxParameters",
\s*"(?<XPosition>XPosition):=" , "(?<XPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<YPosition>YPosition):=" , "(?<YPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<ZPosition>ZPosition):=" , "(?<ZPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<XSize>XSize):=" , "(?<XSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<YSize>YSize):=" , "(?<YSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<ZSize>ZSize):=" , "(?<ZSizeValue>-?\d.?(\d?)+mm)"
\s*\],
能把前一个中括号的内容给读书来，并通过组的形式获取到各个属性及值。但是我用
oEditor.CreateBox\(
\s*\[
\s*"NAME:BoxParameters",
\s*"(?<XPosition>XPosition):=" , "(?<XPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<YPosition>YPosition):=" , "(?<YPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<ZPosition>ZPosition):=" , "(?<ZPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<XSize>XSize):=" , "(?<XSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<YSize>YSize):=" , "(?<YSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<ZSize>ZSize):=" , "(?<ZSizeValue>-?\d.?(\d?)+mm)"
\s*\],
\s*\[
\s*\"NAME:Attributes",
\s*\"Name:=" , "Box1",
\s*\"Flags:=" , "",
\s*\"Color:=" , "(132 132 193)",
\s*\"Transparency:=" , 0,
\s*\"PartCoordinateSystem:=", "Global",
\s*\"UDMId:=" , "",
\s*\"MaterialValue:=" , "\"vacuum\"",
\s*\"SolveInside:=" , True
\s*\]\)
却无法读出整个oEditor.CreateBox对象的所有内容（匹配项也是从文本读取的）。
即使是用
[code=csharpoEditor.CreateBox\(
\s*\[
\s*"NAME:BoxParameters",
\s*"(?<XPosition>XPosition):=" , "(?<XPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<YPosition>YPosition):=" , "(?<YPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<ZPosition>ZPosition):=" , "(?<ZPositionValue>-?\d.?(\d?)+mm)",
\s*"(?<XSize>XSize):=" , "(?<XSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<YSize>YSize):=" , "(?<YSizeValue>-?\d.?(\d?)+mm)",
\s*"(?<ZSize>ZSize):=" , "(?<ZSizeValue>-?\d.?(\d?)+mm)"
\s*\],
\s*\[][/code]
都无法读出第二个中括号的左括号！！
我猜是不是因为正则表达式在空格和换行符方面有一些注意事项我没考虑到？求大神解答~
