使用Java的POI进行Word文档的解析并生成XML格式文档

    如下代码可以实现使用Java的POI进行Word文档的解析并生成XML格式文档功能，此代码编译通过，但是运行有问题，读者可以亲自试试并能否改bug：

import java.io.FileInputStream;
import java.io.FileOutputStream;
import java.io.IOException;
import java.io.InputStream;
import java.io.OutputStream;
import java.io.OutputStreamWriter;
import java.io.Writer;
import java.nio.charset.Charset;

public final class Word2Forrest {

	@SuppressWarnings("unused")
	public Word2Forrest(HWPFDocument doc, OutputStream stream) throws IOException {

			String text = p.text();
			if (text.trim().length() == 0) {
				continue;
			}
			StyleDescription paragraphStyle = styleSheet.getStyleDescription(p.getStyleIndex());
			String styleName = paragraphStyle.getName();
			if (styleName.startsWith("Heading")) {
				if (inCode) {
					closeSource();
					inCode = false;
				}

				int headerLevel = Integer.parseInt(styleName.substring(8));

					openSection();
				} else {
					for (int y = 0; y < (sectionLevel - headerLevel) + 1; y++) {
						closeSection();
					}
					openSection();
				}
				sectionLevel = headerLevel;
				openTitle();
				System.out.println("++++++" + p.text());
				writePlainText(text);
				closeTitle();
			} else {
				int cruns = p.numCharacterRuns();
				CharacterRun run = p.getCharacterRun(0);

				}
			}
		}

		closeDocument();
		_out.flush();
