----------------------------------------------------------------

Here is how I would implement it:

{noformat}
public static String escapeXPath(final String text) {
        final String escaped;
        if (text.indexOf('\'') == -1) {
            escaped = text;
        } else {
            escaped = new StringBuilder(Tv.FIFTY + text.length())
                .append("concat('")
                .append(text.replace("'", "', \"'\", '"))
                .append("')")
                .toString();
        }
        return escaped;
}
{noformat}

> Would be great to create a method that would escape a string for XPath. It is a well
known problem that XPath doesn't have a mechanism for quotes escaping. See for example http://stackoverflow.com/questions/14822153/escape-single-quote-in-xpath-with-nokogiri
> A very good workaround suggested here https://bugs.php.net/bug.php?id=51785
> Would be great to add a method to StringEscapeUtils
