PHP has Xpath 1.0, if you have a string with double and single quotes, a workaround is using the Xpath concat() function. A helper function can decide when to use what. Example/Usage: xpath_string(‘I lowe “double” quotes.’); // xpath: ‘I lowe “double” quotes.’ xpath_string(‘It\’s my life.’); // xpath: “It’s my life.” xpath_string(‘Say: “Hello\’sen”.’); // xpath: concat(‘Say: … Read more
You need to use proper escaping/encoding. Either in HTML using character references: <p onclick=”exampleFunc(‘<div id="divId"></div>’);”>Some Text</p> Or in JavaScript using string escape sequences: <p onclick=”exampleFunc(‘\x3Cdiv\x20id\x3D\x22divId\x22\x3E\x3C/div\x3E’);”>Some Text</p>
Just try noquote(a) noquote(“a”) [1] a
You just need to escape it correctly. alias xxx=”svn status | awk ‘\$1 ==\”M\”{print \$2;}'”

execl(“/home/vlc”, “/home/vlc”, “/home/my movies/the movie i want to see.mkv”, (char*) NULL); You need to specify all arguments, included argv[0] which isn’t taken from the executable. Also make sure the final NULL gets cast to char*. Details are here: http://pubs.opengroup.org/onlinepubs/9699919799/functions/exec.html
Everyone who did the test concluded that using single quotes is marginally better performance wise. In the end single quotes result in just a concatenation while double quotes forces the interpreter to parse the complete string for variables. However the added load in doing that is so small for the last versions of PHP that … Read more
This variant – <a title=”Some "text"”>Hover me</a> Is correct and it works as expected – you see normal quotes in rendered page.
" is on the official list of valid HTML 4 entities, but ' is not. From C.16. The Named Character Reference ‘: The named character reference ' (the apostrophe, U+0027) was introduced in XML 1.0 but does not appear in HTML.
