escaping

I am generating XML using Apache Velocity. What is the best (most straight-forward) way to XML-escape the output? (I saw there is an escape tool, but could not figure out it's dev state. I also think that XML escaping is something that is very likely supported by Velocity directly.) Take a look at event handlers . eventhandler.referenceinsertion.class = org.apache.velocity.app.event.implement.EscapeXmlReference Escape tool is a production ready as well if you need to escape only selective references (final version of tools was released just recently but it was in beta stage before that for 2

I need to write an argument to a file in a Bash script, so I'm doing something like this, echo "Argument is: $1" >> file The problem is that if there's a tilde (~) in the argument I don't want it expanded to the home directory. So if the user passed ~/bin as an argument to the script, it would get written as ~/bin and not /home/user/bin. How do I do this? I assume your program is started as: $ your_prog ~/foo The argument is translated before your program is even started, so there's nothing you can do to prevent it other than educating the user to quote appropriately if the expansion is not

I need a help in escaping in groovy I have some string in text file like this #$commonTomcat620.max_threads$# These value i have to replace in runTime. I used following code: def str = "#\$commonTomcat620.max_threads\$#" fileContents = fileContents.replaceAll("${str}","100"); This str is printin the values as #$commonTomcat620.max_threads$#. but not replacing in file. I tried withOut #$ . it is working. Thanks. You have a couple of options to escape the dollar sign: This works (with dollar-slashy strings): def str = $/#\$$commonTomcat620.max_threads\$$#/$ Or this (with single quote strings):

I have a string in python 3 that has several unicode representations in it, for example: t = 'R\\u00f3is\\u00edn' and I want to convert t so that it has the proper representation when I print it, ie: >>> print(t) Róisín However I just get the original string back. I've tried re.sub and some others, but I can't seem to find a way that will change these characters without having to iterate over each one. What would be the easiest way to do so? abarnert You want to use the built-in codec unicode_escape . If t is already a bytes (an 8-bit string), it's as simple as this: >>> print(t.decode(

I have a field of strings in a data frame all similar to: "Young Adult – 8-9"" where the inner single " is what I want to replace with nothing to get: "Young Adult - 8-9" How can I do this? I tried to escape with a double backslash: gsub("\\"", "", string) but got this error: Error: unexpected string constant in "gsub("\"", "" You do not need to escape a double quote in a regular expression. Just use "\"" or '"' to match a single double quote. s = "Young Adult – 8-9\"" s [1] "Young Adult – 8-9\"" gsub("\"", "", s) [1] "Young Adult – 8-9" gsub('"', "", s) [1] "Young Adult – 8-9" See this IDEONE

I need to export some data using SQL Server 2000's BCP utility. Sometimes my data contains characters, such as \t and \n, that I need to use as column and row terminators. How do I get BCP to escape characters it's using as terminators as it outputs the data, so that I can actually import the data in another program? For example, one of my columns is text data, and includes tabs and newlines. BCP just exports them as-is, and the program I'm trying to import them with gets confused because the data ends in the middle of a line and/or a line contains extra columns for no apparent reason.
