Question

我需要提取两个不同的数字，前面有两个不同的字符串。 Employee Id--> Employee16（我需要16）和 Employee links--> Employee links:2（我需要2）。 Source String如下所示：

Employee16, Employee name is QueenRose
  Working for 46w0d
  Billing is Distributed
  65537 assigned tasks, 0 reordered, 0 unassigned
  0 discarded, 0 lost received, 5/255 load
  received sequence unavailable, 0xC2E7 sent sequence
  Employee links: 2 active, 0 inactive (max not set, min not set)
    Dt3/5/10:0, since 46w0d, no tasks pending
    Dt3/5/10:10, since 21w0d, no tasks rcvd
 Employee is currently working in Hardware section.

Employee19, Employee name is Edward11
  Working  for 48w4d
  Billing is Distributed
  206801498 assigned tasks, 0 reordered, 0 unassigned
  655372 discarded, 0 lost received, 9/255 load
  received sequence unavailable, 0x23CA sent sequence
  Employee links: 7 active, 0 inactive (max not set, min not set)
    Dt3/5/10:0, since 47w2d, tasks pending
    Dt3/5/10:10, since 28w6d, no tasks pending
    Dt3/5/10:11, since 18w4d, no tasks pending
    Dt3/5/10:12, since 18w4d, no tasks pending
    Dt3/5/10:13, since 18w4d, no tasks pending
    Dt3/5/10:14, since 18w4d, no tasks pending
    Dt3/5/10:15, since 7w2d, no tasks pending
   Employee is currently working in Hardware sectione.

Employee6 (inactive)
  Employee links: 2
    Dt3/5/10:0 (inactive)
    Dt3/5/10:10 (inactive)

Employee7 (inactive)
  Employee links: 2
    Dt3/5/10:0 (inactive)
    Dt3/5/10:10 (inactive)

尝试以下内容：

Employee(\d+)[^\n\r]*[^M]*Employee links:\s+(\d+)

期望输出如下：

但是没有列出所有的ID和链接。有人可以帮我解决这个问题吗？

Answer 1

最简单的方法是从两个不同的位置提取两个独立的匹配步骤。如果您将整个文本首先拆分为段落，那么到目前为止最简单。

Employee Id--> Employee16（我需要16）

我会像这样提取一个：

regexp -line {^Employee(\d+),} $paragraph -> employeeNumber

（您希望此任务的行匹配模式，而不是默认的“整个字符串”匹配模式。）

Employee links--> Employee links:2（我需要2）

对于这个，再次假设我们只关注单个员工的整体记录：

regexp -line {^\s+Employee links:\s*(\d+)(.*)$} $paragraph -> links rest

在这种情况下，我不仅提取了$links，还提取了该行的$rest，因为您似乎可能需要考虑是否重要。当然，可能以下内容更有用：

regexp -line {^\s+Employee links:\s*(\d+)(?:\s+active,\s+(\d+)\s+inactive)?} \ $paragraph -> activeLinks inactiveLinks

在这种情况下，如果只存在第一个数字，$inactiveLinks将有一个空字符串（这似乎发生在员工处于非活动状态时;你需要做一些微不足道的逻辑来整理在那种情况下）。

最后，在使用regexp时，不要忘记检查结果是否匹配！希望这会有所帮助。

Answer 2

我打算提供一个完整的答案，但后来我读了Donal更多有用的教程，觉得我不能。我将展示如何将文本拆分成段落：

foreach paragraph [regexp -all -inline {.*?\n{2,}} $text] {
    do something with $paragraph
}

在您的尝试中，我看到[^\n\r]* - 您确定您的文字和换行符中是否有回车符？

使用Tcl Regular Expression从段落中提取2个不同的字符串
