在Android中解析doc,docx,xls,xlsx,pptx等格式文件
导读：有的时候我们在开发android中需要解析一些我们比较常用的格式，比如doc、docx、xls、xlsx，那么我们要是正常的话就解析不了。这时我们就要用tm-extractors-0.4.jar。
可以直接复制实验，
解析doc，要tm-extractors-0.4.jar这个包
解析xls，要jxl.jar这个包

解析doc :
View Code
public static String readDOC(String path) { // 创建输入流读取doc文件 FileInputStream in; String text = null; // Environment.getExternalStorageDirectory().getAbsolutePath()+ "/aa.doc") try { in = new FileInputStream(new File(path)); int a= in.available(); WordExtractor extractor = null; // 创建WordExtractor extractor = new WordExtractor(); // 对doc文件进行提取 text = extractor.extractText(in); System.out.println("解析得到的东西"+text); } catch (FileNotFoundException e) { e.printStackTrace(); } catch (Exception e) { e.printStackTrace(); } if (text == null) { text = "解析文件出现问题"; } return text; }
解析xls :
View Code
public static String readXLS(String path) { String str = ""; try { Workbook workbook = null; workbook = Workbook.getWorkbook(new File(path)); Sheet sheet = workbook.getSheet(0); Cell cell = null; int columnCount = sheet.getColumns(); int rowCount = sheet.getRows(); for (int i = 0; i < rowCount; i++) { for (int j = 0; j < columnCount; j++) { cell = sheet.getCell(j, i); String temp2 = ""; if (cell.getType() == CellType.NUMBER) { temp2 = ((NumberCell) cell).getValue() + ""; } else if (cell.getType() == CellType.DATE) { temp2 = "" + ((DateCell) cell).getDate(); } else { temp2 = "" + cell.getContents(); } str = str + " " + temp2; } str += "\n"; } workbook.close(); } catch (Exception e) { } if (str == null) { str = "解析文件出现问题"; } return str; }
解析docx :
public static String readDOCX(String path) { String river = ""; try { ZipFile xlsxFile = new ZipFile(new File(path)); ZipEntry sharedStringXML = xlsxFile.getEntry("word/document.xml"); InputStream inputStream = xlsxFile.getInputStream(sharedStringXML); XmlPullParser xmlParser = Xml.newPullParser(); xmlParser.setInput(inputStream, "utf-8"); int evtType = xmlParser.getEventType(); while (evtType != XmlPullParser.END_DOCUMENT) { switch (evtType) { case XmlPullParser.START_TAG: String tag = xmlParser.getName(); System.out.println(tag); if (tag.equalsIgnoreCase("t")) { river += xmlParser.nextText() + "\n"; } break; case XmlPullParser.END_TAG: break; default: break; } evtType = xmlParser.next(); } } catch (ZipException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } if (river == null) { river = "解析文件出现问题"; } return river; }
解析xlsx :
View Code
public static String readXLSX(String path) { String str = ""; String v = null; boolean flat = false; List<String> ls = new ArrayList<String>(); try { ZipFile xlsxFile = new ZipFile(new File(path)); ZipEntry sharedStringXML = xlsxFile .getEntry("xl/sharedStrings.xml"); InputStream inputStream = xlsxFile.getInputStream(sharedStringXML); XmlPullParser xmlParser = Xml.newPullParser(); xmlParser.setInput(inputStream, "utf-8"); int evtType = xmlParser.getEventType(); while (evtType != XmlPullParser.END_DOCUMENT) { switch (evtType) { case XmlPullParser.START_TAG: String tag = xmlParser.getName(); if (tag.equalsIgnoreCase("t")) { ls.add(xmlParser.nextText()); } break; case XmlPullParser.END_TAG: break; default: break; } evtType = xmlParser.next(); } ZipEntry sheetXML = xlsxFile.getEntry("xl/worksheets/sheet1.xml"); InputStream inputStreamsheet = xlsxFile.getInputStream(sheetXML); XmlPullParser xmlParsersheet = Xml.newPullParser(); xmlParsersheet.setInput(inputStreamsheet, "utf-8"); int evtTypesheet = xmlParsersheet.getEventType(); while (evtTypesheet != XmlPullParser.END_DOCUMENT) { switch (evtTypesheet) { case XmlPullParser.START_TAG: String tag = xmlParsersheet.getName(); if (tag.equalsIgnoreCase("row")) { } else if (tag.equalsIgnoreCase("c")) { String t = xmlParsersheet.getAttributeValue(null, "t"); if (t != null) { flat = true; System.out.println(flat + "有"); } else { System.out.println(flat + "没有"); flat = false; } } else if (tag.equalsIgnoreCase("v")) { v = xmlParsersheet.nextText(); if (v != null) { if (flat) { str += ls.get(Integer.parseInt(v)) + " "; } else { str += v + " "; } } } break; case XmlPullParser.END_TAG: if (xmlParsersheet.getName().equalsIgnoreCase("row") && v != null) { str += "\n"; } break; } evtTypesheet = xmlParsersheet.next(); } System.out.println(str); } catch (ZipException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } if (str == null) { str = "解析文件出现问题"; } return str; }
解析pptx :
View Code
public static String readPPTX(String path) { List<String> ls = new ArrayList<String>(); String river = ""; ZipFile xlsxFile = null; try { xlsxFile = new ZipFile(new File(path));// pptx按照读取zip格式读取 } catch (ZipException e1) { e1.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } try { ZipEntry sharedStringXML = xlsxFile.getEntry("[Content_Types].xml");// 找到里面存放内容的文件 InputStream inputStream = xlsxFile.getInputStream(sharedStringXML);// 将得到文件流 XmlPullParser xmlParser = Xml.newPullParser();// 实例化pull xmlParser.setInput(inputStream, "utf-8");// 将流放进pull中 int evtType = xmlParser.getEventType();// 得到标签类型的状态 while (evtType != XmlPullParser.END_DOCUMENT) {// 循环读取流 switch (evtType) { case XmlPullParser.START_TAG: // 判断标签开始读取 String tag = xmlParser.getName();// 得到标签 if (tag.equalsIgnoreCase("Override")) { String s = xmlParser .getAttributeValue(null, "PartName"); if (s.lastIndexOf("/ppt/slides/slide") == 0) { ls.add(s); } } break; case XmlPullParser.END_TAG:// 标签读取结束 break; default: break; } evtType = xmlParser.next();// 读取下一个标签 } } catch (ZipException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } for (int i = 1; i < (ls.size() + 1); i++) {// 假设有6张幻灯片 river += "第" + i + "张················" + "\n"; try { ZipEntry sharedStringXML = xlsxFile.getEntry("ppt/slides/slide" + i + ".xml");// 找到里面存放内容的文件 InputStream inputStream = xlsxFile .getInputStream(sharedStringXML);// 将得到文件流 XmlPullParser xmlParser = Xml.newPullParser();// 实例化pull xmlParser.setInput(inputStream, "utf-8");// 将流放进pull中 int evtType = xmlParser.getEventType();// 得到标签类型的状态 while (evtType != XmlPullParser.END_DOCUMENT) {// 循环读取流 switch (evtType) { case XmlPullParser.START_TAG: // 判断标签开始读取 String tag = xmlParser.getName();// 得到标签 if (tag.equalsIgnoreCase("t")) { river += xmlParser.nextText() + "\n"; } break; case XmlPullParser.END_TAG:// 标签读取结束 break; default: break; } evtType = xmlParser.next();// 读取下一个标签 } } catch (ZipException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } catch (XmlPullParserException e) { e.printStackTrace(); } } if (river == null) { river = "解析文件出现问题"; } return river; }
