replace

问题 I have a text file that is being written to as part of a very large data extract. The first line of the text file is the number of "accounts" extracted. Because of the nature of this extract, that number is not known until the very end of the process, but the file can be large (a few hundred megs). What is the BEST way in C# / .NET to open a file (in this case a simple text file), and replace the data that is in the first "line" of text? IMPORTANT NOTE : - I do not need to replace a "fixed

问题 Ok, I am trying to filter a list/dictionary passed to me and "clean" it up a bit, as there are certain values in it that I need to get rid of. So, if it's looking like this: "records": [{"key1": "AAA", "key2": "BBB", "key3": "CCC", "key4": "AAA"...}] How would I quickly and easily run through it all and replace all values of "AAA" with something like "XXX"? Focus is on speed and resources, as these may be long lists and I don't want this process to consume too much time. 回答1: DATA = {"records

问题 I have a pandas dataframe (that was created by importing a csv file). I want to replace blank values with NaN. Some of these blank values are empty and some contain a (variable number) of spaces '' , ' ' , ' ' , etc. Using the suggestion from this thread I have df.replace(r'\s+', np.nan, regex=True, inplace = True) which does replace all the strings that only contain spaces, but also replaces every string that has a space in it, which is not what I want. How do I replace only strings with

问题 I want to write a JavaScript function which converts some simple BBcode Tags like [red] [/red] to Html-Tags. I think the replace() function is the best way to do it. I wrote a simple testfunction to try it, but it does not seem to work. /** * @function * @description Replaces the bb-tags with html-tags */ function bbToHtml(form) { debugger var text = form.text.value; bbTags = new Array("[red]", "[yellow]", "[green]", "[/red]", "[/yellow]", "[/green]"); htmlTags = new Array("<font color='red'>

问题 I have a program that loads lines from a user file, then selects the last part of the String (which would be an int) Here's the style it's saved in: nameOfValue = 0 nameOfValue2 = 0 and so on. I have selected the value for sure - I debugged it by printing. I just can't seem to save it back in. if(nameOfValue.equals(type)) { System.out.println(nameOfValue+" equals "+type); value.replace(value, Integer.toString(Integer.parseInt(value)+1)); } How would I resave it? I've tried bufferedwriter but

问题 I'm still learning my ropes with SQL Server and maybe this question sounds very naive/ridiculous. Please bear with me on this. :) I saw a function in SQL Server defined as below: CREATE FUNCTION [dbo].[fn_CleanNumeric] ( @InputString VARCHAR(500) ) RETURNS NVARCHAR(500) as BEGIN SELECT @InputString = REPLACE(@InputString, n.Symbol, '') FROM NonNumeric n RETURN @InputString END NonNumeric is a table with a column named, [Symbol] , containing a bunch of non-numeric ASCII characters.

问题 I'm trying to turn a set of keywords into links on my site. I am currently using this code which will turn one keyword into a link. However, now I want to expand it to have several words. The link will always be the same, however, the keyword changes, so the link text must also reflect that. Here is the code I am currently using: <script type="text/javascript"> (function($) { var thePage = $("body"); thePage.html(thePage.html().replace(/Wedding Stationery/ig, '<a class="discrete" href="http:/
