Question

我想将下面的XML文件转换为另一个由XSLT完成的XML文件。

我使用下面的XSL代码来获取要返回的新XML。

<xsl:stylesheet version="1.0"
 xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output method="xml" version="1.0" encoding="UTF-8" omit-xml-declaration="yes" indent="yes"/>

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

 <xsl:template match=
 "property
   [not(contains('|unit|apartment|',
                 concat('|',type,'|')
                 ))
    or
     not(numberofBedrooms > 1) or not(propertyavailable='yes')
   ]
 ">
</xsl:template>

<xsl:template match="property">
<xsl:element name="property">
<xsl:attribute name="contact">
<xsl:value-of select="contact" />
      </xsl:attribute>

<xsl:element name="type">
<xsl:value-of select="type" />
</xsl:element>
<xsl:element name="price">
<xsl:value-of select="price" />
</xsl:element>
<xsl:element name="address">
   <xsl:value-of select=
   "concat(streetNo, ' ', street, ', ',
           suburb,', ', state,' ' , zipcode,', Australia')
   "/>
</xsl:element>
<xsl:element name="numberofBedrooms">
<xsl:value-of select="numberofBedrooms" />
</xsl:element>
<xsl:element name="numberofBathrooms">
<xsl:value-of select="numberofBathrooms" />
</xsl:element>
<xsl:element name="description">
<xsl:value-of select="description" />
</xsl:element>
</xsl:element>
</xsl:template>

</xsl:stylesheet>

我想用上面的XSL将StreetNo，街道，郊区，州，邮政编码连接到地址元素，但我现在得到的输出是：

<?xml version="1.0" encoding="UTF-8"?>
<rentalProperties>
   <property contact="0407106699">
      <type>apartment</type>
      <price>450</price>

      <numberofBedrooms>3</numberofBedrooms>
      <numberofBathrooms>1</numberofBathrooms>
      <description>Recently completed, the ultra-stylish and light-filled dimensions of this brand new first floor Scotch Hill apartment provide an enviable lifestyle of sophistication,...</description>
   </property>

      <numberofBathrooms>1</numberofBathrooms>
      <description>This generous 2 bedroom villa unit located close to Glenferrie Road boasts a bright living area with polished floor boards opening to a low maintenance courtyard, fully renovated kitchen with gas cooking and dishwasher, built in robes to both bedrooms, bathroom and separate laundry.</description>
   </property>
   <property contact="0398105000">
      <type>apartment</type>
      <price>420</price>
      <address>, ,  , Australia</address>
      <numberofBedrooms>2</numberofBedrooms>
      <numberofBathrooms>1</numberofBathrooms>
      <description>Benefiting beautifully from its 1st floor position directly overlooking the leafy environs of Urquhart St, this sun-bathed apartment is located near exciting eateries, boutiques, tram, train and Swinburne Uni.</description>
   </property>
</rentalProperties>

地址元素没有获取其他元素值，并且将区域留空。

<address>, ,  , Australia</address>

此段的XSL代码是否有问题：

<xsl:element name="address">
   <xsl:value-of select=
   "concat(streetNo, ' ', street, ', ',
           suburb,', ', state,' ' , zipcode,', Australia')
   "/>
</xsl:element>

Answer 1

您的模板与property匹配，select是XPath streetNo表达式的当前上下文。在该模板中，您可以选择street，<xsl:template match="property"> ... <xsl:element name="address"> <xsl:value-of select= "concat(streetNo, ' ', street, ', ', suburb,', ', state,' ' , zipcode,', Australia') "/> </xsl:element>等：

property/streetNo

这意味着您实际上正在选择property/street，<property available="yes" contact="0423020899"> ... <address> <streetNo>116</streetNo> ...等

根据您的XML来源：

property

没有这样的元素，因此表达式不会匹配任何内容，结果会得到空字符串。

在address上下文中，您想要的元素位于<xsl:element name="address"> <xsl:value-of select= "concat(address/streetNo, ' ', address/street, ', ', address/suburb,', ', address/state,' ' , address/zipcode,', Australia') "/> </xsl:element>内。您可以通过向选择器添加缺少的位置步骤来修复表达式：

{{1}}

使用XSLT的XML到XML省略了特定元素和连接
