c++ - Python RE - Regular expression for matching a printf-like format string with escaped quotation marks -


I am writing a small + preprocessor in Python, which should have format strings like printf. I need a regular expression, which corresponds to other quote marks in the first place, but ('' '' ') is ignoring all the escape marks. Here is an example: 

  foo bar, "value \" s \ ":% s", "foobar");

I need a regex for this: 

  "value \":

I have so far: 

  (". *?")

But I could not find any way to avoid quotation marks I'm so grateful if someone can give me a solution / tip.

Thank you in advance!

You can try regex below to match the first of all the characters Hala and the other ", 

  \". *] [^ \\] \ "

< Previous> & gt; & Gt; & Gt; S = r'foo (bar, "value \" s \ ":% s", "foobar"); '& Gt; & Gt; & Gt; M = re.search (r '". *? [^ \\]"', s)> gt; & Gt; & Gt; Results = m.group (0)> gt; & Gt; & Gt; Print result "value \" s \ ":% s"

Explanation:

  • "< / Code> matches the first double quote marks.
  • . *? Any characters match zero or more times. ? After * matches an unwillingness. << Li> matches << code> " (Double quote) symbol

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment. Was hoping that it would be something like this MessageBox.Show (AmortGrid.SelectedItem.PaymentNo.ToString ()); When you call ToString () So you get the class typ
