正则表达式提取三重双引号和换行符之间

Question

For example i want to parse python file with text between triple double quotes and make html table from this text.

Text block for example like that

"""
Replaces greater than operator ('>') with 'NOT BETWEEN 0 AND #'
Replaces equals operator ('=') with 'BETWEEN # AND #'

Tested against:
    * Microsoft SQL Server 2005
    * MySQL 4, 5.0 and 5.5
    * Oracle 10g
    * PostgreSQL 8.3, 8.4, 9.0

Requirement:
    * Microsoft Access

Notes:
    * Useful to bypass weak and bespoke web application firewalls that
      filter the greater than character
    * The BETWEEN clause is SQL standard. Hence, this tamper script
      should work against all (?) databases

>>> tamper('1 AND A > B--')
'1 AND A NOT BETWEEN 0 AND B--'
>>> tamper('1 AND A = B--')
'1 AND A BETWEEN B AND B--'
"""

Html table must be simple table contains 5 columns

1. Column everything between """ and \\n if new line is empty
2. Column everything between Tested against: and \\n if new line is empty or Requirement: and \\n if new line is empty
3. Column everything between Notes: and \\n if new line is empty
4. Column everything between >>> and \\n
5. Column everything between 4 column end and \\n

So result must be:

1. Replaces greater than operator ('>') with 'NOT BETWEEN 0 AND #' Replaces equals operator ('=') with 'BETWEEN # AND #'

2. • Microsoft SQL Server 2005

     • MySQL 4, 5.0 and 5.5
     • Oracle 10g
     • PostgreSQL 8.3, 8.4, 9.0

     or

     • Microsoft Access
3. • Useful to bypass weak and bespoke web application firewalls that filter the greater than character
   • The BETWEEN clause is SQL standard. Hence, this tamper script should work against all (?) databases

4. tamper('1 AND A > B--') tamper('1 AND A = B--')

5. '1 AND A NOT BETWEEN 0 AND B--' '1 AND A BETWEEN B AND B--'

What kind of syntax can i use to extract that? I will use VBScript.RegExp .

Set fso = CreateObject("Scripting.FileSystemObject")
txt = fso.OpenTextFile("C:\path\to\your.py").ReadAll

Set re = New RegExp
re.Pattern = """([^""]*)"""
re.Global = True

For Each m In re.Execute(txt)
  WScript.Echo m.SubMatches(0)
Next

Your question is quite broad, so I'll just outline a way to deal with this. Otherwise I'd have to write the whole script for you, which isn't going to happen.

1. Extract everything between the docquotes. Use a regular expression like this to extract the text between the docquotes:

    Set re1 = New RegExp re1.Pattern = """""""([\\s\\S]*?)""""""" For Each m In re1.Execute(txt) docstr = m.SubMatches(0) Next 

   Note that you need to set the re.Global to True if you have more than 1 docstring in your file and want all of them processed. Otherwise you'll get just the first match.

2. Remove leading and trailing whitespace with a second regular expression:

    Set re2 = New RegExp re2.Pattern = "^\\s*|\\s*$" re2.Global = True 'find all matches docstr = re2.Replace(docstr, "") 

   You can't use Trim for this, because the function handles only spaces, not other whitespace.

3. Either split the string at 2+ consecutive line breaks to get the doc sections, or use another regular expression to extract them:

    Set re3 = New RegExp re3.Pattern = "([\\s\\S]*?)\\r\\n\\r\\n" + "Tested against:\\r\\n([\\s\\S]*?)\\r\\n\\r\\n" + ... For Each m In re3.Execute(txt) descr = m.SubMatches(0) tested = m.SubMatches(1) ... Next 

Continue breaking down the sections until you have the elements you want to display. Then build the HTML from these elements.
