No. |
Notes |
|---|---|
|
1 |
If you specify a document function followed by an XPath expression, use /descendant-or-self::node()/ instead of //. |
|
2 |
Do not use the current function in the top-level element. |
|
3 |
If you use the node test node() in an XPath expression, nodes cannot be obtained properly. |
|
4 |
If you code an XPath expression that combines a node test including an * (asterisk) with a logical operator as the XPath expression, an error occurs during the parsing of the XPath expression. |
|
5 |
If the value of a variable or parameter is a result tree fragment (not a value in the select attribute, but a value defined by the template that is coded as an element content), a NullPointerException may occur when there is a variable reference in the template. |
