This is how I would implement it:
{noformat}
public static String escapeXPath(final String text) {
final String escaped;
if (text.indexOf('\'') == -1) {
escaped = new StringBuilder(text.length() + 2)
.append('\'').append(text).append('\'').toString();
} else {
escaped = new StringBuilder(Tv.FIFTY + text.length())
.append("concat('")
.append(text.replace("'", "', \"'\", '"))
.append("')")
.toString();
}
return escaped;
}
{noformat}

> Components: lang.*
> Affects Versions: 3.3.2
> Reporter: Yegor Bugayenko
>
> 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
