Headers

toUrl :: FilePath -> String Source #

This also sanitizes the URL, e.g. converting spaces into '%20'

Stripping/escaping

Example:

stripTags "<p>foo</p>"

Result:

"foo"

This also works for incomplete tags

Example:

stripTags "<p>foo</p"

Result:

"foo"

escapeHtml :: String -> String Source #

HTML-escape a string

Example:

escapeHtml "Me & Dean"

Result:

"Me &amp; Dean"
