Perl RegEx: Limiting the pattern to only the first occurrence of a character -

-

I am trying to extract the contents of a date element with many sick SGML documents. For example, the document might have a simple date element such as

or 

  & lt; DATE blaAttrib = "89787adjd98d9" & gt; 4 July 1936 & lt; / DATE & gt;

But it can also be in the form of hair: 

  & lt; DATE blaAttrib = "89787adjd98d9" & gt; 4 July 1936 & lt; EM & gt; EM element within the date & lt; / EM & gt; & Lt; / DATE & gt; The purpose is to get "July 4, 1936" since the files are not large, so I read the entire contents in a variable and chose to regex. The following is a snippet of my Perl code:  
  {local $ / = undef; Open the file, "$ file" or die "File can not be opened: $!"; $ FileContent = & lt; FILE & gt; Close the file; If ($ fileContent = ~ m / & lt; DATE (. *) & Gt; (. *) & Lt; / DATE & gt; /) {# $ 2 should be "4 July 1936", but It did not happen. }}  
 
 Unfortunately, regex does not work for hair examples. The reason for this is that  & lt; DATE & gt;  inside a  & lt; EM & gt;  element and it also spreads to many rows. 
 
 Can any kind of spirit give me some signs, instructions, or clues? 
 
 Thanksgiving!

.

But by your example, maybe you can try 

  if ($ fileContent = ~ m / & lt; DATE [^ & gt;] * & gt; ([^ & Lt;] +) /) {# $ 1 Use # You may need to strip new lines}

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
