Examples with XPath com.sun.org.apache.xpath.internal.XPath used on opensource projects

Example 1 with XPath

use of com.sun.org.apache.xpath.internal.XPath in project jdk8u_jdk by JetBrains.

the class XalanXPathAPI method createXPath.

private XPath createXPath(String str, PrefixResolver prefixResolver) throws TransformerException {
    XPath xpath = null;
    Class<?>[] classes = new Class<?>[] { String.class, SourceLocator.class, PrefixResolver.class, int.class, ErrorListener.class, FunctionTable.class };
    Object[] objects = new Object[] { str, null, prefixResolver, Integer.valueOf(XPath.SELECT), null, funcTable };
    try {
        Constructor<?> constructor = XPath.class.getConstructor(classes);
        xpath = (XPath) constructor.newInstance(objects);
    } catch (Exception ex) {
        if (log.isLoggable(java.util.logging.Level.FINE)) {
            log.log(java.util.logging.Level.FINE, ex.getMessage(), ex);
        }
    }
    if (xpath == null) {
        xpath = new XPath(str, null, prefixResolver, XPath.SELECT, null);
    }
    return xpath;
}
