问题 I'm trying to escape ('\') a semicolon (';') in a string on unix shell (bash) with sed. It works when I do it directly without assigning the value to a variable. That is, $ echo "hello;" | sed 's/\([^\\]\);/\1\\;/g' hello\; $ However, it doesn't appear to work when the above command is assigned to a variable: $ result=`echo "hello;" | sed 's/\([^\\]\);/\1\\;/g'` $ $ echo $result hello; $ Any idea why? I tried by using the value enclosed with and without quotes but that didn't help. Any clue

Safe html in java

由 故事扮演 提交于 2019-12-02 01:21:46
I have some input containing HTML like <br> <b> <i> etc. I need a way to escape only the "bad" HTML that exposes my site to XSS etc. After hours of Googeling I found the GWT which looks kinda promising.

Google caja is a tool for making third party HTML, CSS and JavaScript safe to embed in your website. OWASP AntiSamy is a project for just that. If you need users to be able to submit structured text,

Escaping <? on php shorthand enabled server when using require

由 无人久伴 提交于 2019-12-01 23:45:36
I'm trying to require() my template for rss feed in php. Unfortunately I need to have shorthand tags enabled on server I'm working with.
