Question

我正在尝试使用jsoup从xml中提取文本，但也保留了一些标签，因为它们很有用，如何实现呢？

也许就像迭代文档并通过它的标签取出一个组件，然后迭代该组件并根据嵌套标签提取更新。但我无法解决这个问题。

           for( Element item : doc.select("sentence") )
           {
               for( Element component : item)
               {
                   get the tag of sentence and the words of the 
                   sentence as described below
               } 
           }

我有一个以这种方式标记的xml文档：

<sentences>
  <sentence id="1">
    <tokens>
      <token id="1">
        <word>The</word>
        <CharacterOffsetBegin>0</CharacterOffsetBegin>
        <CharacterOffsetEnd>3</CharacterOffsetEnd>
      </token>
      <token id="2">
        <word>newspaper</word>
        <CharacterOffsetBegin>4</CharacterOffsetBegin>

      </token>
      <token id="3">

      <token id="5">

      <token id="6">

        <CharacterOffsetBegin>34</CharacterOffsetBegin>
        <CharacterOffsetEnd>41</CharacterOffsetEnd>
      </token>
      <token id="7">
        <word>Per-Kristian</word>
        <CharacterOffsetBegin>42</CharacterOffsetBegin>
        <CharacterOffsetEnd>54</CharacterOffsetEnd>
      </token>
      <token id="8">
        <word>Foss</word>
        <CharacterOffsetBegin>55</CharacterOffsetBegin>
        <CharacterOffsetEnd>59</CharacterOffsetEnd>
      </token>
      <token id="9">
        <word>,</word>
        <CharacterOffsetBegin>59</CharacterOffsetBegin>
        <CharacterOffsetEnd>60</CharacterOffsetEnd>
      </token>
      <token id="10">

      </token>
      <token id="11">
        <word>finance</word>
        <CharacterOffsetBegin>65</CharacterOffsetBegin>
        <CharacterOffsetEnd>72</CharacterOffsetEnd>
      </token>
      <token id="12">
        <word>minister</word>
        <CharacterOffsetBegin>73</CharacterOffsetBegin>
        <CharacterOffsetEnd>81</CharacterOffsetEnd>
      </token>
      <token id="13">
        <word>of</word>

      <token id="15">

      </token>
      <token id="16">
        <word>buoyed</word>
        <CharacterOffsetBegin>93</CharacterOffsetBegin>
        <CharacterOffsetEnd>99</CharacterOffsetEnd>
      </token>
      <token id="17">
        <word>by</word>
        <CharacterOffsetBegin>100</CharacterOffsetBegin>
        <CharacterOffsetEnd>102</CharacterOffsetEnd>
      </token>
      <token id="18">
        <word>a</word>
        <CharacterOffsetBegin>103</CharacterOffsetBegin>
        <CharacterOffsetEnd>104</CharacterOffsetEnd>
      </token>
      <token id="19">
        <word>spouting</word>
        <CharacterOffsetBegin>105</CharacterOffsetBegin>
        <CharacterOffsetEnd>113</CharacterOffsetEnd>
      </token>
      <token id="20">
        <word>geyser</word>
        <CharacterOffsetBegin>114</CharacterOffsetBegin>
        <CharacterOffsetEnd>120</CharacterOffsetEnd>
      </token>
      <token id="21">
        <word>of</word>
        <CharacterOffsetBegin>121</CharacterOffsetBegin>
        <CharacterOffsetEnd>123</CharacterOffsetEnd>
      </token>
      <token id="22">
        <word>oil</word>
        <CharacterOffsetBegin>124</CharacterOffsetBegin>
        <CharacterOffsetEnd>127</CharacterOffsetEnd>
      </token>
      <token id="23">
        <word>.</word>
        <CharacterOffsetBegin>127</CharacterOffsetBegin>
        <CharacterOffsetEnd>128</CharacterOffsetEnd>
      </token>
    </tokens>
  </sentence>

理想的输出是：

<sentence id="1">
    The newspaper cartoons here often portray Per-Kristian Foss, the finance minister of Norway, buoyed by a spouting geyser of oil. 
</sentence>

等文档的其余部分，可能包含许多句子，或者也可能只包含一个句子。

到目前为止，我试过了：

String sentence = doc.select("sentence").text();

但我得到的只是这个烂摊子：

The 0 3 newspaper 4 13 cartoons 14 22 here 23 27 often 28 33 portray 34 41 Per-Kristian 42

Answer 1

瞧

           for( Element item : doc.select("sentence") )
           {
               System.out.println("<sentence> " + index );

               String word = item.select("word").text();

               System.out.println(word);

              System.out.println("</sentence>" + "\n");

               index++;
           }

有选择地使用jsoup从xml中提取文本和一些有用的标签
