  I'm working on 2 cases: assume I have those var: a = "hello" b = "hello-SP" b = "not_hello" 1 - Any partial matches I want to accept any string that has the var a inside, so b and c would match. 2 - Patterned match I want to match a string that has a inside, followed by '-', so b would match, c does not. I am having problem, because I always used the syntax /expression/ to define Regexp, so how dinamicaly define an RegExp on Ruby??

  I know that Selenium has a built-in method getTable("tableName.row.column") can return a cell conveniently. However how can I return a whole column?

• Append or modify keys in conf files using sed/bash one-liner

  - by Jeff

  I often have to modify files such as sysctl.conf, and I'm familiar with using sed to replace existing values. Is there a way to append the new key/value pair to the file if sed wasn't able to replace it? For instance, using this example: modify config file using bash script sed -c -i "s/\($TARGET_KEY *= *\).*/\1$REPLACEMENT_VALUE/" $CONFIG_FILE How could I add the $TARGET_KEY = $REPLACEMENT_VALUE new line to $CONFIG_FILE using the same sed expression with slight changes? And on a related topic, how can I force creation of $CONFIG_FILE if it didn't exist?

• Find all <a>s to who's href points to an image with XPath 1.0

  - by Jeffrey Aylesworth

  First, I can assume that all urls that end with jpeg, jpg, bmp, png or gif are images, and others aren't. I thought of, and tried two solutions: Matching the regular expression .(jpe?g|bmp|png|gif)$ Using ends-with to check each separately But, it appears that neither of these exist in XPath 1.0, or at least, they don't exist in Firefox (I am writing a greasemonkey script, so it is only important for the path to work in Firefox).

• Good starting point to learn regular expressions.

  - by Jeremy Rudd

  I'm good at learning new languages and platforms, though whenever I try to learn Reg Ex I cannot make sense of it. I once even used the Regular Expression Designer to try and put some together. What's a good starting point to understanding what looks like the only rocket-science programming language in the world? Links to articles, books or anything else that could help me get my grounding would be appreciated.
