Invalid XPath expression exception due to presence of apostrophe in name

Question

I am getting Invalid Xpath Exception for following code.

current.Name = current.Name.replace("'", "\'");
System.out.println(current.Name );
String xp1 = "//page[@name='"+current.Name+"']" ;
Element n = (Element) oDocument.selectSingleNode(xp1+"/Body/contents");

Exception occurs when the string in current.name has an apostrophe in it

current.name: "Répartition par secteur d'activité"

Answer 1

You can escape the quote by doubling it:

current.Name = current.Name.replace("'", "''");

EDIT:

For Xpath 1.0, you could try the following:

String xp1 = "//page[@name=\""+current.Name+"\"]" ;

I.e. Use double quotes instead of single quotes to delimit the name (though that means you won't be able to search for strings with a double quote.

Note also, for the second solution you won't need to replace the quotes.
