Diesel表达式-在分隔符后选择正确的值-
我想取选项卡后的最后一个数字 -示例I序列号，即文件名。
1.dwg |2.dwg |...|985.dwg
在本例中，审阅为 0（零）必须具有此值
当项目具有审阅 adiociono 分隔符 -
1-1.dwg此项目具有 1 个审阅。
2-5.dwg该项目有5个评论。
985-15.dwg此项目有 15 个修订版 - kkkkk 哦，
我的上帝，我试图搜索 Diesel 表达式 SPLIT 方法，但没有。
如何获取自定义字段
，我正在等待
谢谢
**** Hidden Message ***** 也许这会有所帮助。
我使用类似的表达式来解析图形名称并删除/包含破折号或其他文本。 您可能需要修改此 ..但拿走你需要的东西。
$（substr，$（getvar，dwgname），1，3）
将返回绘图名称的前三个字母。
我想这取决于您的绘图命名约定的完整图案化。在评论计数之前，您是否有固定的字符数？
这可能也会有所帮助。

Dumb Interpretively Evaluated String Expression Language
This "Dumb Interpretively Executed String Expression Language" isthe

embedding it into your program.
It is short, written in portable C, and is readily integrated into any
program. Itisusefulprimarilytoprograms whichneed a very
rudimentary macro expansion facility without the complexity of afull
language such as Lisp or FORTH.

character, "$" or quoted string is encountered.Quoted strings may be
usedtosuppress evaluationof sequences of characters which would
otherwise be interpreted as macros.Quote marks maybeincluded in
quoted strings by two adjacent quote marks.For example:
"$(if,1,True,False)="""$(if,1,True,False)""""
Statusretrieval, computation,anddisplay are performed by DIESEL
functions. The availablefunctionsareasfollows. User-defined

DIESEL String Functions
-----------------------
$(+,,,...)
Thesumofthenumbers , , ... is returned.
$(-,,,...)
Theresultof subtracting the numbersthroughfrom
is returned.
$(*,,,...)
The result of multiplying the numbers,,... is
returned.
$(/,,,...)
Theresult of dividing the numberby ,... is
returned.
$(=,,)
If the numbers and areequal1isreturned,
otherwise 0 is returned.
$(,)
Ifthe numberis less than1 is returned, otherwise
0 is returned.
$(>,,)
If the number isgreaterthan 1isreturned,
otherwise 0 is returned.
$(!=,,)
Ifthenumbers and are not equal 1 is returned,
otherwise 0 is returned.
$(,)
If the number isless thanorequalto 1 is
returned, otherwise 0 is returned.
$(>=,,)
Ifthenumber isgreaterthan or equal to1 is
returned, otherwise 0 is returned.
$(AND,,,...)
The bitwise logical AND of the integersthrough is
returned.
$(EQ,,)
If the stringsand areidentical1isreturned,
otherwise 0.
$(EVAL,)
Thestringis passed to the DIESEL evaluator and the result
of evaluating it is returned.
$(FIX,)
The real numberis truncated to an integerby discarding
any fractional part.
$(IF,,,)
If is nonzero, is evaluatedand returned.
Otherwise, isevaluatedand returned.Note that the
branch not chosen byis not evaluated.
$(INDEX,,)
is assumed to contain one or more values delimited by the
macro argument separator character, comma. selects one of
these values to be extracted, with the first itemnumberedzero.
$(NTH,,,,)
Evaluatesand returnstheargument selectedby. If
is 0,is returned, and so on.Note the difference
between$(NTH)and$(INDEX);$(NTH) returns one of a series of
arguments to the function while $(INDEX) extracts a valuefroma
comma-delimited string passed as a single argument.Arguments not
selected byare not evaluated.
$(OR,,,...)
ThebitwiselogicalOR of the integersthroughis
returned.
$(STRFILL,,)
Returns the result of concatenatingof .
$(STRLEN,)
Returns the length ofin characters.
$(SUBSTR,,,)
Returnsthesubstringofstarting at character
and extending forcharacters. Characters inthestring
are numbered from 1.Ifis omitted, the entire remaining
length of the string is returned.
$(UPPER,)
The is returned converted to upper case according to the
rules of the current locale.
$(XOR,,,...)
The bitwise logical XOR of the integersthrough is
returned.

我会建议如下，但我相信DIESEL对计算表达式有256个字符的限制，所以这不太可能奏效。
$(if,$(eq,-,$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),6),1)),
$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),5),2),
$(if,$(eq,-,$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),5),1)),
$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),4),1),
0
)
)
这里有一个类似的话题：
https://www.theswamp.org/index.php?topic=48081.0 您最好的选择是对文件名进行标准化。柴油不识别连字符作为分隔符，非常确定它只是CSV样式。
我会从000-00到985-15等。
015-12
将返回12
123-05
将返回05
如果您的修订符号至少始终为 2 位数字（01 到 99），则可以使用数学函数来确定位置开始
字符串 - 5（（2 位数字加上“.dwg”），
因此无论您的文件名长度如何，都可以在 “.
喜欢这个。。。。
$(substr,$(getvar,dwgname),$(-,$(strlen,$(getvar,dwgname)),5),2)
无论字符数如何，它都会返回“.”之前的最后两位数字。
