使用Java提取XML结构

分类: 技术问答 • 2022-07-04 12:02:32
问题描述：

是否有Java库可以让您提取/创建XML文档，因此最终结果是文档的“准系统”XML结构。使用Java提取XML结构

例

<result> 
    <rowset name="kills" key="killID" columns="killID,solarSystemID,killTime,moonID"> 
     <row killID="54933226" solarSystemID="31001222" killTime="2016-07-03 22:29:19" moonID="0"> 
     <victim characterID="93811169" characterName="Madcat326" corporationID="98008818" corporationName="Haight Industries LLC" allianceID="0" allianceName="" factionID="0" factionName="" damageTaken="63039" shipTypeID="17918" x="59788513854.179" y="-13687850177.3741" z="157817245029.115" /> 
     <rowset name="attackers" columns="characterID,characterName,corporationID,corporationName,allianceID,allianceName,factionID,factionName,securityStatus,damageDone,finalBlow,weaponTypeID,shipTypeID"> 
      <row characterID="91316135" characterName="Celeo Servasse" corporationID="98134538" corporationName="Wormbro" allianceID="0" allianceName="" factionID="0" factionName="" securityStatus="-1.0646369409683" damageDone="7825" finalBlow="1" weaponTypeID="3520" shipTypeID="12003" /> 
      <row characterID="95273329" characterName="Mupoc Kashuken" corporationID="98134538" corporationName="Wormbro" allianceID="0" allianceName="" factionID="0" factionName="" securityStatus="-0.2" damageDone="16656" finalBlow="0" weaponTypeID="31882" shipTypeID="12023" /> 
     </rowset> 
     <rowset name="items" columns="typeID,flag,qtyDropped,qtyDestroyed,singleton"> 
      <row typeID="394" flag="20" qtyDropped="1" qtyDestroyed="0" singleton="0" /> 
      <row typeID="24427" flag="32" qtyDropped="0" qtyDestroyed="1" singleton="0" /> 
      <row typeID="2446" flag="87" qtyDropped="1" qtyDestroyed="1" singleton="0" /> 
      <row typeID="28209" flag="87" qtyDropped="2" qtyDestroyed="0" singleton="0" /> 
     </rowset> 
     </row> 
    </rowset> 
</result>

将重建为类似

<result> 
    <rowset name="kills" key="killID" columns="killID,solarSystemID,killTime,moonID"> 
     <row killID="54933226" solarSystemID="31001222" killTime="2016-07-03 22:29:19" moonID="0"> 
     <victim characterID="93811169" characterName="Madcat326" corporationID="98008818" corporationName="Haight Industries LLC" allianceID="0" allianceName="" factionID="0" factionName="" damageTaken="63039" shipTypeID="17918" x="59788513854.179" y="-13687850177.3741" z="157817245029.115" /> 
     <rowset name="attackers" columns="characterID,characterName,corporationID,corporationName,allianceID,allianceName,factionID,factionName,securityStatus,damageDone,finalBlow,weaponTypeID,shipTypeID"> 
      <row characterID="91316135" characterName="Celeo Servasse" corporationID="98134538" corporationName="Wormbro" allianceID="0" allianceName="" factionID="0" factionName="" securityStatus="-1.0646369409683" damageDone="7825" finalBlow="1" weaponTypeID="3520" shipTypeID="12003" /> 
     </rowset> 
     <rowset name="items" columns="typeID,flag,qtyDropped,qtyDestroyed,singleton"> 
      <row typeID="394" flag="20" qtyDropped="1" qtyDestroyed="0" singleton="0" /> 
     </rowset> 
     </row> 
    </rowset> 
</result>

或者我怎么可以提取/创建XML文档的结构？

如果这个过程被称为别的东西，请让我知道。

您的意思是你想要生成一个模式？ – Paddyd

这听起来并不完全错误，我真正想要的是能够获取XML文档并获得其构建结构。 –

要得到一个有用的答案，你应该解释你期望能够对结果做什么。

您可以使用在线工具（如http://www.freeformatter.com/xsd-generator.html或http://xmlgrid.net/xml2xsd.html）以XSD格式提取结构，那么您在寻找什么？

嗨特里斯坦，谢谢你的回复！除了能够在没有冗余数据的情况下查看文档结构（如行，父节点内没有子节点）之外，我不打算将结果/输出用于任何其他内容。我试图在上面的帖子/主题中展示这一点。 –

在浏览器中使用XML编辑器或XML查看器？ – jschnasse

是的，正如@jschnasse所建议的那样，您可以在任何XML编辑器（如浏览器）中折叠包含多个元素的级别。 – Tristan

以下XSLT转换格式可能有助于删除重复的子行元素。你可以从java代码运行这个转换器。

<?xml version="1.0" encoding="UTF-8"?> 
    <xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
    <xsl:template match="/result"> 
     <result> 
     <rowset> 
     <xsl:copy-of select="rowset/@*"/>  
     <row> 
     <xsl:copy-of select="rowset/row/@*"/>  
     <victim> 
      <xsl:copy-of select="rowset/row/victim/@*"/>  
     </victim>   
     <rowset>  
      <xsl:copy-of select="rowset/row/rowset[@name='attackers']/@*"/> 
      <row> 
      <xsl:copy-of select="rowset/row/rowset[@name='attackers']/row[1]/@*"/> 
      </row> 
     </rowset> 
      <rowset>  
      <xsl:copy-of select="rowset/row/rowset[@name='items']/@*"/> 
      <row> 
      <xsl:copy-of select="rowset/row/rowset[@name='items']/row[1]/@*"/> 
      </row> 
     </rowset> 
     </row> 
     </rowset> 
     </result> 
     </xsl:template> 
    </xsl:stylesheet>
