展平第三方XML Feed?

我正在尝试从第三方来源获取XML Feed并将其展平。

当前的XML Feed类似于:

<properties>
    <property>
        <idnumber></idnumber>
        <location>
            <region></region>
            <street-address></street-address>
            <city-name></city-name>
            <state-code></state-code>
            <zipcode></zipcode>
            <latitude></latitude>
            <longitude></longitude>
        </location>
        <details>
            <name></name>
            <status></status>
            <price></price>
            <bedrooms></num-bedrooms>
            <bathrooms></bathrooms>
            <lot-size></lot-size>
            <square-feet></square-feet>
            <property-type></property-type>
            <attributes></attributes>
            <description></description>
        </details>
        <pictures>
            <picture>
                <picture-url></picture-url>
            </picture>
    </property>
</properties>

但是,我真的需要将XML展平为:

<properties>
    <property>
        <idnumber></idnumber>
        <region></region>
        <street-address></street-address>
        <city-name></city-name>
        <state-code></state-code>
        <zipcode></zipcode>
        <latitude></latitude>
        <longitude></longitude>
        <name></name>
        <status></status>
        <price></price>
        <bedrooms></num-bedrooms>
        <bathrooms></bathrooms>
        <lot-size></lot-size>
        <square-feet></square-feet>
        <property-type></property-type>
        <attributes></attributes>
        <description></description>
        <picture>
                <picture-url></picture-url>
        </picture>
    </property>
</properties>

我一直在阅读XLST样式表以尝试这一点,但是我只是浪费时间,因为原始供稿是在我无法编辑的第三方托管的?

此转化

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>
 <xsl:strip-space elements="*"/>

 <xsl:template match="node()|@*">
  <xsl:copy>
   <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="/*/*/*[*]">
   <xsl:apply-templates/>
 </xsl:template>
</xsl:stylesheet>

应用于提供的XML文档(更正为格式良好):

<properties>
    <property>
        <idnumber></idnumber>
        <location>
            <region></region>
            <street-address></street-address>
            <city-name></city-name>
            <state-code></state-code>
            <zipcode></zipcode>
            <latitude></latitude>
            <longitude></longitude>
        </location>
        <details>
            <name></name>
            <status></status>
            <price></price>
            <bedrooms></bedrooms>
            <bathrooms></bathrooms>
            <lot-size></lot-size>
            <square-feet></square-feet>
            <property-type></property-type>
            <attributes></attributes>
            <description></description>
        </details>
        <pictures>
            <picture>
                <picture-url></picture-url>
            </picture>
        </pictures>
    </property>
</properties>

生成所需的正确输出

<properties>
   <property>
      <idnumber/>
      <region/>
      <street-address/>
      <city-name/>
      <state-code/>
      <zipcode/>
      <latitude/>
      <longitude/>
      <name/>
      <status/>
      <price/>
      <bedrooms/>
      <bathrooms/>
      <lot-size/>
      <square-feet/>
      <property-type/>
      <attributes/>
      <description/>
      <picture>
         <picture-url/>
      </picture>
   </property>
</properties>

解释:正确使用并覆盖 the identity rule

这将做你想要的。身份模板将所有内容复制到输出,而其他三个模板导致第二级标记在复制其内容时被省略。

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:output method="xml" indent="yes"/>

 <xsl:template match="@*|node()">
  <xsl:copy>
   <xsl:apply-templates select="@*|node()"/>
  </xsl:copy>
 </xsl:template>

 <xsl:template match="property/location">
  <xsl:apply-templates/>
 </xsl:template>

 <xsl:template match="property/details">
  <xsl:apply-templates/>
 </xsl:template>

 <xsl:template match="property/pictures">
  <xsl:apply-templates/>
 </xsl:template>

</xsl:stylesheet>
