XmlObjectList是什么类？XmlObjectList xolist = new XmlObjectList();
在VTD解析xml时，调用了它，是自己写的吗？





package VTD;



import java.util.ArrayList;

import java.util.HashMap;

import java.util.List;



import com.ximpleware.AutoPilot;

import com.ximpleware.BookMark;

	public List getObjectFromXml(String FileName, String SelectPath, int count)

			throws XPathParseException, XPathEvalException, NavException {

		List tablist = new ArrayList();

		// 初始化 VTD 执行 触发器

		VTDGen vg = new VTDGen();

		int i;

		// 根据xpath装入xml文件

		AutoPilot ap = new AutoPilot();

		// SelectPath 如: 根节点/子节点 根据xml的层级设置合适的路径深度

		ap.selectXPath(SelectPath);

		//SelectPath:"/page/tab"

		// 节点位置以单例模式装入记忆坐标

		BookMark bm = new BookMark();

		// 装入要解析的文件返回是否解析成功

		if (vg.parseFile(FileName, false)) {

//This method parses the XML file and returns a boolean indicating if it is successful or not

			VTDNav vn = vg.getNav();

			bm.bind(vn);

			ap.bind(vn);



			while ((i = ap.evalXPath()) != -1) {

				// 获得tab 节点集

				XmlObjectList xolist = new XmlObjectList();

				xolist.setName(vn.toString(vn.getAttrVal("name")));

				xolist.setReadonly(vn.toString(vn.getAttrVal("readonly")));

				xolist.setDesc(vn.toString(vn.getAttrVal("desc")));

				tablist.add(xolist);



				xolist.setTabList(tablist);



				bm.recordCursorPosition(); // equivalent to vn.push();

//这个地方很重要不刷新的话第一层就不能全部循环出来。

				// get to the first child

				XmlFieldObject xfo = new XmlFieldObject();

				List xfolist = new ArrayList();

				if (vn.toElement(VTDNav.FIRST_CHILD, "field")) {

//					找元素"field"

					int j = vn.getText();

					if (j != -1)

					xfo.setName(vn.toString(vn.getAttrVal("name")));

					xfo.setReadonly(vn.toString(vn.getAttrVal("readonly")));

					xfo.setDesc(vn.toString(vn.getAttrVal("desc")));

					xfolist.add(xfo);

				}

					XmlFieldObject xfso = new XmlFieldObject();

					if (vn.toElement(VTDNav.NEXT_SIBLING)) {

						int j = vn.getText();

							xfso.setName(vn.toString(vn.getAttrVal("name")));

						xfso

								.setReadonly(vn.toString(vn

										.getAttrVal("readonly")));

						xfso.setDesc(vn.toString(vn.getAttrVal("desc")));

						xfolist.add(xfso);

					}

				}

				// 将filelis装载到tab对象

				xolist.setFileList(xfolist);

				bm.setCursorPosition();

			// 这个地方很重要不刷新的话第一层就不能全部循环出来。

			}

			// 这句的意思应该是重设xpath

			ap.resetXPath();

		}



		return tablist;

	}
