Compiling an xpath expression - has an invalid token

I am trying to compile an xpath expression that is made dynamically and receiving an exception that - "it has an invalid token".

text =  GetText(); // has this value: /root/Info/PublisherName1 = "abcd"
XPathResultType result = XPathExpression.Compile(text).ReturnType;

I have tried escaping the double quotes using the following code, but still receiving the same exception:

text = text.Replace("\"", "\\\"");
text = text.Replace("'", "\\'");

After trying to escape the quotes as above, the string still have the single quotes inside without showing any backslash when seen in the debugger.

How can this be done?

/root/Info/PublisherName1 = "abcd" is invalid XPath for methods from System.Xml.XPath namespace

I believe you are looking for something like this: /root/Info/PublisherName1[text() = "abcd"]

The Expression is a valid XPath expression, the problem is the quotes are coming from a Microsoft Word file and we need to replace smart quotes with straight quotes as follows:

text = text.Replace('\u2018', '\'')
.Replace('\u2019', '\'')
.Replace('\u201c', '\"')
.Replace('\u201d', '\"')
.Replace('\u201e', '\"')
.Replace('\u2033', '\"');

Then, it works without any problem.

Sorry @Kirill, I have to deselect your answer.
