Methods
| Name | Description |
|---|---|
| EscapeSpecialChatactersIfNeeded(Boolean, Boolean) |
XPath doesn't have any good support for escape. The best way to do this is to concatenate the character e.g. a'b becomes concat('a', "'", 'b') a"b becomes concat("a", '"', "b") Because we also do our own parsing on top of XPath parsing having single quotes and double quotes in our parser can be a problem We optionally replace the expressions "'" and '"' with tokens that we can change back |
| EvaluatePathFunctions() |
Returns XPath function in human readable format. e.g. Given a constant function like Name=concat('a', 'b', 'c') this returns the evaluated XPath, i.e Name='abc' in this case if the string contains double or single quotes they will be replaced with macros to avoid our parser getting confused e.g Name=concat('a', "'", 'b') becomes Name='a@@singlequote@@b' instead of Name='a'b' |
| EvaluateToken(Dictionary<String,String>) | |
| GetOperatorString(Byte) | |
| IsBoolOperator() | |
| ToString() | |
| Unescape() |
Gets rid of single quote and double quote macros and replces them with the actual values in preparation for querying XPath |
