java删除XML重复标记

Question

我收到的一些xml如下：

<cite id="0ac50429-bfbd-74e5-81bf-be29583cba3b">
<cite id="0ac50429-bfbd-74e5-81bf-be2a36aec2df">
<cite id="0ac50429-bfbd-74e5-81bf-be3d125bdc1c">Some Text
</cite>
</cite>
</cite>
<p>random text</p>
<cite id="0ac50429-bfbd-74e5-81bf-be29583cba3b">
<cite id="0ac50429-bfbd-74e5-81bf-be2a36aec2df">
<cite id="0ac50429-bfbd-74e5-81bf-be3d125bdc1c">
More text
</cite>
</cite>
</cite>

正如你所看到的，对于相同的值，我有不止一个标记，而我只需要每个文本有一个标记：

<cite id="0ac50429-bfbd-74e5-81bf-be3d125bdc1c">Some Text</cite>
<p>random text</p>
<cite id="0ac50429-bfbd-74e5-81bf-be29583cba3b">More text</cite>

但我找不到一个好办法来摆脱它。有人有线索吗？我试着要最后一个孩子，但我就是找不到。我试过使用正则表达式，我可以得到最后一个节点，但我不能正确地替换它们，以获得所需的xml。 泰

这是我的解决方案（我不能回答自己的问题，所以我写在这里：）

我知道这不是最好的，而且可以做得更好，这很有效

private static String replaceNodes(String simpleRegex, String xml)
{

    String tagMultiple;
    String expresionRegular = "("+simpleRegex+")+";

    Pattern pattern = Pattern.compile(expresionRegular);
    Matcher matcher = pattern.matcher(xml);


    while(matcher.find())  // Here we look for all the nodes that are repeated . EJ  <cite id="asda"><cite id="asda"><cite id="asda">
    {
         Pattern patternSimple = Pattern.compile(simpleRegex);
        Matcher matcherSimple = patternSimple.matcher(xml);
        String tagUnicoEnd ="";
        if (matcherSimple.find()) //Here we get only one node. <cite id="asda">
            tagUnicoEnd = matcher.group(1);         

        tagMultiple = matcher.group();                  
        xml =xml.replace(tagMultiple,tagUnicoEnd);  //we replace all the repetead nodes, with the unique one.
    }       

    return xml;                         
}

最后我找到了一个方法，我知道这不是最好的，可以做得更好

private static String replaceNodes(String simpleRegex, String xml)
{

    String tagMultiple;
    String expresionRegular = "("+simpleRegex+")+";

    Pattern pattern = Pattern.compile(expresionRegular);
    Matcher matcher = pattern.matcher(xml);


    while(matcher.find())  // Here we look for all the nodes that are repeated . EJ  <cite id="asda"><cite id="asda"><cite id="asda">
    {
         Pattern patternSimple = Pattern.compile(simpleRegex);
        Matcher matcherSimple = patternSimple.matcher(xml);
        String tagUnicoEnd ="";
        if (matcherSimple.find()) //Here we get only one node. <cite id="asda">
            tagUnicoEnd = matcher.group(1);         

        tagMultiple = matcher.group();                  
        xml =xml.replace(tagMultiple,tagUnicoEnd);  //we replace all the repetead nodes, with the unique one.
    }       

    return xml;                         
}
