这是我的代码:
public static void main(String[] args) {
// System.setProperty(
// "javax.xml.xpath.XPathFactory",
// "net.sf.saxon.xpath.XPathFactoryImpl");
String xml="<root><a>#BBB#</a><a>#CCC#</a><b><a>#DDD#</a></b></root>";
try{
JDocument dom = new JDocument(xml);
XPathFactory factory = net.sf.saxon.xpath.XPathFactoryImpl.newInstance();
XPath xpath = factory.newXPath();
XPathExpression expr = xpath.compile("//a[matches(.,'#...#')]");
Object result = expr.evaluate(dom, XPathConstants.NODESET);
NodeList nodes = (NodeList) result;
Nodes sharped = new Nodes(nodes);
for (Node n:sharped){
System.out.println(n.toString());
}
}
catch(Exception e){
e.printStackTrace();
}
}
我明白了:
javax.xml.transform.TransformerException: Impossible to find the function : matches
at org.apache.xpath.compiler.XPathParser.error(XPathParser.java:608)
at org.apache.xpath.compiler.XPathParser.FunctionCall(XPathParser.java:1505)
at org.apache.xpath.compiler.XPathParser.PrimaryExpr(XPathParser.java:1444)
at org.apache.xpath.compiler.XPathParser.FilterExpr(XPathParser.java:1343)
at org.apache.xpath.compiler.XPathParser.PathExpr(XPathParser.java:1276)
这意味着org.apache.xpath.compiler.XPathParser
当我通过net.sf.saxon.xpath.XPathFactoryImpl
.
(我实际上只需要matches
在我的 xpaths 中放一些......所以如果知道任何不涉及撒克逊的解决方案,请考虑满足我的需要)。
我究竟做错了什么 ?
