Example 1 with XPathFactory

use of org.jdom2.xpath.XPathFactory in project gocd by gocd.

the class UniqueOnCancelValidator method validate.

public void validate(Element element, ConfigElementImplementationRegistry registry) throws Exception {
    XPathFactory xPathFactory = XPathFactory.instance();
    List<String> tasks = ConfigUtil.allTasks(registry);
    for (String task : tasks) {
        List<Element> taskNodes = xPathFactory.compile("//" + task, Filters.element()).evaluate(element);
        for (Element taskNode : taskNodes) {
            List<Element> list = xPathFactory.compile("oncancel", Filters.element()).evaluate(taskNode);
            if (list.size() > 1) {
