您好，我正在尝试从 html 页面（打印机的静态页面）中选择 4 个值，但我遇到了一些问题。我有一些尝试都失败了，请你们帮助我：

孔页 = http://pastebin.com/e7eKAV0x

意向代码：

               <tr>                        
                 <td>                      
                   Yellow Cartridge
                   <br>
                   Order 305A (CE412A)
                 </td>
                 <td class="alignRight valignTop">  
                         40%
                       †
                 </td>
               </tr>

（请使用检查/检查页面）我需要来自 4 个不同字段（打印机颜色）的 40% 值。当颜色消失时 --

我的最后一次尝试：

public void buildCartigesAndValue(String ipString) throws IOException {
        LOGGER.log(Level.INFO, "Starting mining over IP " + ipString);
        String context = getUrlSource(ipString);
        System.out.println(context); 

        urlPart = "/info_colorUsageJobLog.html?tab=Status&menu=ColorUsageLog";
        if (context.contains("HP Color LaserJet CP2025dn") || context.contains("HP Color LaserJet CM2320nf MFP")) {
            LOGGER.log(Level.INFO, "PRINTER TYPE ======= HP Color LaserJet CP2025dn");
            regexColorContent = "\\w+\\W{1}Cartridge (?<!Printer)";
            regexTagContent = "(<td{1}>)([^<]{1}[^.{20}][^&nbsp;&nbsp;].*?)(</td>)";
        }
        else if (context.contains("HP LaserJet 400 color M451dw")){
            LOGGER.log(Level.INFO, "PRINTER TYPE ======= HP LaserJet 400 color M451dw");
            regexColorContent = "\\w+\\W{1}Cartridge (?<!Printer)";
            regexTagContent = "Cartridge.{50}";
        }

        List<Integer> vals = findCartegisProcentr(context);
        List<String> colors = findCartigesColor(context);
        for (int i = 0; i < colors.size(); i++) {
            if (colors.get(i).contains("Printer")) {
                continue;
            }
            System.out.println(colors.get(i));
            addNewColorVal(colors.get(i), vals.get(i));
        }
        LOGGER.log(Level.INFO, "Stopping sucessfully ---- MAP ---- " + this.colorAmountMap.toString());
    }


public List<Integer> findCartegisProcentr(String context) {
    List<Integer> vals = new ArrayList<>();

    regexValContent = "\\d{2}|-{2}"; // FOR PARTICULAR THE VALUES

    Pattern patternTagContent = Pattern.compile(regexTagContent);
    Matcher matcherTagContent = patternTagContent.matcher(context);

    Pattern patternValContent = Pattern.compile(regexValContent);
    while (matcherTagContent.find()) {
        Matcher matcherValContent = patternValContent
                .matcher(matcherTagContent.group());
        matcherValContent.find();
        try {
            vals.add(Integer.parseInt(matcherValContent.group()));
        } catch (Exception e) {
            vals.add(0);
        }
    }
    return vals;
}
