本文提供了解析doc、docx、xls及xlsx文件的方法。通过Java代码示例，展示了如何读取这些文件的内容，并针对不同文件类型使用了特定的技术手段。

解析doc，请下载tm-extractors-0.4.jar、解析xls，请下载jxl.jar包。

一、解析doc文件：

01 public static String readDOC(String path) {

02 // 创建输入流读取doc文件

03 FileInputStream in;

04 String text = null;

05 // Environment.getExternalStorageDirectory().getAbsolutePath()+ "/aa.doc")

06 try {

07 in = new FileInputStream(new File(path));

08 int a= in.available();

09 WordExtractor extractor = null;

10 // 创建WordExtractor

11 extractor = new WordExtractor();

12 // 对doc文件进行提取

13 text = extractor.extractText(in);

14 System.out.println("解析得到的东西"+text);

15 } catch (FileNotFoundException e) {

16 e.printStackTrace();

17 } catch (Exception e) {

18 e.printStackTrace();

19 }

20 if (text == null) {

21 text = "解析文件出现问题";

22 }

23 return text;

24 }

二、解析xls文件：

01 public static String readXLS(String path) {

02 String str = "";

03 try {

04 Workbook workbook = null;

05 workbook = Workbook.getWorkbook(new File(path));

06 Sheet sheet = workbook.getSheet(0);

07 Cell cell = null;

08 int columnCount = sheet.getColumns();

09 int rowCount = sheet.getRows();

10 for (int i = 0; i < rowCount; i++) {

11 for (int j = 0; j < columnCount; j++) {

12 cell = sheet.getCell(j, i);

13 String temp2 = "";

14 if (cell.getType() == CellType.NUMBER) {

15 temp2 = ((NumberCell) cell).getValue() + "";

16 } else if (cell.getType() == CellType.DATE) {

17 temp2 = "" + ((DateCell) cell).getDate();

18 } else {

19 temp2 = "" + cell.getContents();

20 }

21 str = str + " " + temp2;

22 }

23 str += " ";

24 }

25 workbook.close();

26 } catch (Exception e) {

27 }

28 if (str == null) {

29 str = "解析文件出现问题";

30 }

31 return str;

32 }

三、解析docx文件：

01 public static String readDOCX(String path) {

02 String river = "";

03 try {

04 ZipFile xlsxFile = new ZipFile(new File(path));

05 ZipEntry sharedStringXML = xlsxFile.getEntry("word/document.xml");

06 InputStream inputStream = xlsxFile.getInputStream(sharedStringXML);

07 XmlPullParser xmlParser = Xml.newPullParser();

08 xmlParser.setInput(inputStream, "utf-8");

09 int evtType = xmlParser.getEventType();

10 while (evtType != XmlPullParser.END_DOCUMENT) {

11 switch (evtType) {

12 case XmlPullParser.START_TAG:

13 String tag = xmlParser.getName();

14 System.out.println(tag);

15 if (tag.equalsIgnoreCase("t")) {

16 river += xmlParser.nextText() + " ";

17 }

18 break;

19 case XmlPullParser.END_TAG:

20 break;

21 default:

22 break;

23 }

24 evtType = xmlParser.next();

25 }

26 } catch (ZipException e) {

27 e.printStackTrace();

28 } catch (IOException e) {

29 e.printStackTrace();

30 } catch (XmlPullParserException e) {

31 e.printStackTrace();

32 }

33 if (river == null) {

34 river = "解析文件出现问题";

35 }

36 return river;

37 }

四、解析xls文件：

01 public static String readXLSX(String path) {

02 String str = "";

03 String v = null;

04 boolean flat = false;

05 List<String> ls = new ArrayList<String>();

06 try {

07 ZipFile xlsxFile = new ZipFile(new File(path));

08 ZipEntry sharedStringXML = xlsxFile

09 .getEntry("xl/sharedStrings.xml");

10 InputStream inputStream = xlsxFile.getInputStream(sharedStringXML);

11 XmlPullParser xmlParser = Xml.newPullParser();

12 xmlParser.setInput(inputStream, "utf-8");

13 int evtType = xmlParser.getEventType();

14 while (evtType != XmlPullParser.END_DOCUMENT) {

15 switch (evtType) {

16 case XmlPullParser.START_TAG:

17 String tag = xmlParser.getName();

18 if (tag.equalsIgnoreCase("t")) {

19 ls.add(xmlParser.nextText());

20 }

21 break;

22 case XmlPullParser.END_TAG:

23 break;

24 default:

25 break;

26 }

27 evtType = xmlParser.next();

28 }

29 ZipEntry sheetXML = xlsxFile.getEntry("xl/worksheets/sheet1.xml");

30 InputStream inputStreamsheet = xlsxFile.getInputStream(sheetXML);

31 XmlPullParser xmlParsersheet = Xml.newPullParser();

32 xmlParsersheet.setInput(inputStreamsheet, "utf-8");

33 int evtTypesheet = xmlParsersheet.getEventType();

34 while (evtTypesheet != XmlPullParser.END_DOCUMENT) {

35 switch (evtTypesheet) {

36 case XmlPullParser.START_TAG:

37 String tag = xmlParsersheet.getName();

38 if (tag.equalsIgnoreCase("row")) {

39 } else if (tag.equalsIgnoreCase("c")) {

40 String t = xmlParsersheet.getAttributeValue(null, "t");

41 if (t != null) {

42 flat = true;

43 System.out.println(flat + "有");

44 } else {

45 System.out.println(flat + "没有");

46 flat = false;

47 }

48 } else if (tag.equalsIgnoreCase("v")) {

49 v = xmlParsersheet.nextText();

50 if (v != null) {

51 if (flat) {

52 str += ls.get(Integer.parseInt(v)) + " ";

53 } else {

54 str += v + " ";

55 }

56 }

57 }

58 break;

59 case XmlPullParser.END_TAG:

60 if (xmlParsersheet.getName().equalsIgnoreCase("row")

61 && v != null) {

62 str += " ";

63 }

64 break;

65 }

66 evtTypesheet = xmlParsersheet.next();

67 }

68 System.out.println(str);

69 } catch (ZipException e) {

70 e.printStackTrace();

71 } catch (IOException e) {

72 e.printStackTrace();

73 } catch (XmlPullParserException e) {

74 e.printStackTrace();

75 }

76 if (str == null) {

77 str = "解析文件出现问题";

78 }

79 return str;

80 }
