...
XPath xpath = XPathFactory.newInstance().newXPath();
String xpathExpression = " ";
NodeList resultList = (NodeList)xpath.evaluate(xpathExpression,document,XPathConstants.NODESET);
请问如何选择 指定书名的书元素？
弱弱的以为 xpathExpression ="//BOOK[BOOKNAME=bookName]"
可是 会有很多的 xpath 未知错误
javax.xml.transform.TransformerException: XPATH 未知错误
另外如果 需要模糊匹配，弱弱的以为 xpathExpression = "//BOOK[contains(BOOKNAME,bookName)]"
但是也是有同样的错误
麻烦各位了。。。
