我有一些非常简单的 XML.我正在重新创建一些 XML并在最终的XML文件中添加一些样板文本,以便在完成后导入InDesign. 问题在于:并非所有XML字段都在每条记录中使用.因此,当XSLT添加样板文
问题在于:并非所有XML字段都在每条记录中使用.因此,当XSLT添加样板文本时,它甚至会出现在不包含XML元素的记录中.
我尝试使用选择>>当>>否则要查找元素,然后使用元素if,否则忽略样板,如果元素不在记录中,则插入NOTHING.
以下是一些示例XML数据:
<?xml version="1.0" encoding="UTF-8"?> <root> <story> <CL> <CityDescription>City One</CityDescription> <BK> <CompanyName>Corporate Name</CompanyName> <address>123 Main St</address> <HoldingCo>Company Name</HoldingCo> <TotalAssets>128,319,000</TotalAssets> <TotalLiabilities>117,059,000</TotalLiabilities> <TotalDeposits>89,847,000</TotalDeposits> <EquityCapital>11,260,000</EquityCapital> </BK> <BK> <CompanyName>Smaller Company</CompanyName> <address>123 Central St</address> </BK> </CL> <CL> <CityDescription>City Two</CityDescription> <BK> <CompanyName>Corporate Name Three</CompanyName> <address>123 High St</address> <HoldingCo>Company Name</HoldingCo> <TotalAssets>128,319,000</TotalAssets> <TotalLiabilities>117,059,000</TotalLiabilities> <TotalDeposits>89,847,000</TotalDeposits> <EquityCapital>11,260,000</EquityCapital> </BK> <BK> <CompanyName>Smaller Company Four</CompanyName> <address>123 Jones St</address> </BK> </CL> </story> </root>
这是我试图使用的XSLT,但它添加了“Holding Co:”和“Total Assets:”甚至包含不包含元素的记录:
<?xml version="1.0" encoding="UTF-8"?><!-- DWXMLSource="Testing.xml" --> <!DOCTYPE xsl:stylesheet [ ]> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> <xsl:output method="XML" /> <xsl:template match="/"> <root> <story> <xsl:for-each select="root/story/CL"> <CityDescription><xsl:value-of select="CityDescription"/></CityDescription><xsl:text> </xsl:text> <xsl:for-each select="BK"> <CompanyName><xsl:value-of select="CompanyName"/></CompanyName><xsl:text> </xsl:text> <address><xsl:value-of select="address"/></address><xsl:text> </xsl:text> <HoldingCo><xsl:text>Holding Co: </xsl:text><xsl:value-of select="HoldingCo"/></HoldingCo><xsl:text> </xsl:text> <TotalAssets><xsl:text>Total Assets: </xsl:text><xsl:value-of select="TotalAssets"/></TotalAssets><xsl:text> </xsl:text> <TotalLiabilities><xsl:text>Total Liabilities: </xsl:text><xsl:value-of select="TotalLiabilities"/></TotalLiabilities><xsl:text> </xsl:text> <TotalDeposits><xsl:text>Total Deposits: </xsl:text><xsl:value-of select="TotalDeposits"/></TotalDeposits><xsl:text> </xsl:text> <EquityCapital><xsl:text>Total Assets: </xsl:text><xsl:value-of select="EquityCapital"/></EquityCapital><xsl:text> </xsl:text> </xsl:for-each> </xsl:for-each> </story> </root> </xsl:template> </xsl:stylesheet>
我尝试使用Choose>>当>>否则基本上忽略了元素,等等它们没有出现在数据中,但我的输出只显示“否则”内容.
有什么建议?
Here's the problem: not all XML fields are being used in every record. So, when the XSLT adds the boilerplate text it appears even in the records that don't include the XML elements.
这就是模板的用途 – 在XSLT中不使用模板就像不使用OO编程语言中的类.
这个简单的转换(请注意,没有使用过单个条件指令):
<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:variable name="vNL" select="'
'"/> <xsl:template match="/"> <root> <story> <xsl:apply-templates select="root/story/CL"/> </story> </root> </xsl:template> <xsl:template match="CL"> <xsl:apply-templates select="CityDescription"/> <xsl:apply-templates select="BK"/> </xsl:template> <xsl:template match="CityDescription | CompanyName | address"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:template> <xsl:template match="BK"> <xsl:value-of select="$vNL"/> <xsl:apply-templates select="CompanyName"/> <xsl:apply-templates select="address"/> <xsl:apply-templates select="HoldingCo"/> <xsl:apply-templates select="TotalAssets"/> <xsl:apply-templates select="TotalLiabilities"/> <xsl:apply-templates select="TotalDeposits"/> <xsl:apply-templates select="EquityCapital"/> </xsl:template> <xsl:template match="HoldingCo"> <HoldingCo> <xsl:text>Holding Co: </xsl:text> <xsl:value-of select="."/> </HoldingCo> </xsl:template> <xsl:template match="TotalAssets"> <TotalAssets> <xsl:text>Total Assets: </xsl:text> <xsl:value-of select="."/> </TotalAssets> </xsl:template> <xsl:template match="TotalLiabilities"> <TotalLiabilities> <xsl:text>Total Liabilities: </xsl:text> <xsl:value-of select="."/> </TotalLiabilities> </xsl:template> <xsl:template match="TotalDeposits"> <TotalDeposits> <xsl:text>Total Deposits: </xsl:text> <xsl:value-of select="."/> </TotalDeposits> </xsl:template> <xsl:template match="EquityCapital"> <EquityCapital> <xsl:text>Total Assets: </xsl:text> <xsl:value-of select="."/> </EquityCapital> </xsl:template> <xsl:template match="text()"/> </xsl:stylesheet>
当应用于提供的XML文档时:
<root> <story> <CL> <CityDescription>City One</CityDescription> <BK> <CompanyName>Corporate Name</CompanyName> <address>123 Main St</address> <HoldingCo>Company Name</HoldingCo> <TotalAssets>128,319,000</TotalAssets> <TotalLiabilities>117,059,000</TotalLiabilities> <TotalDeposits>89,847,000</TotalDeposits> <EquityCapital>11,260,000</EquityCapital> </BK> <BK> <CompanyName>Smaller Company</CompanyName> <address>123 Central St</address> </BK> </CL> <CL> <CityDescription>City Two</CityDescription> <BK> <CompanyName>Corporate Name Three</CompanyName> <address>123 High St</address> <HoldingCo>Company Name</HoldingCo> <TotalAssets>128,319,000</TotalAssets> <TotalLiabilities>117,059,000</TotalLiabilities> <TotalDeposits>89,847,000</TotalDeposits> <EquityCapital>11,260,000</EquityCapital> </BK> <BK> <CompanyName>Smaller Company Four</CompanyName> <address>123 Jones St</address> </BK> </CL> </story> </root>
产生想要的,正确的结果:
<root> <story> <CityDescription>City One</CityDescription> <CompanyName>Corporate Name</CompanyName> <address>123 Main St</address> <HoldingCo>Holding Co: Company Name</HoldingCo> <TotalAssets>Total Assets: 128,319,000</TotalAssets> <TotalLiabilities>Total Liabilities: 117,059,000</TotalLiabilities> <TotalDeposits>Total Deposits: 89,847,000</TotalDeposits> <EquityCapital>Total Assets: 11,260,000</EquityCapital> <CompanyName>Smaller Company</CompanyName> <address>123 Central St</address> <CityDescription>City Two</CityDescription> <CompanyName>Corporate Name Three</CompanyName> <address>123 High St</address> <HoldingCo>Holding Co: Company Name</HoldingCo> <TotalAssets>Total Assets: 128,319,000</TotalAssets> <TotalLiabilities>Total Liabilities: 117,059,000</TotalLiabilities> <TotalDeposits>Total Deposits: 89,847,000</TotalDeposits> <EquityCapital>Total Assets: 11,260,000</EquityCapital> <CompanyName>Smaller Company Four</CompanyName> <address>123 Jones St</address> </story> </root>
由于BK的子元素按文档顺序处理,匹配模板可简化为:
<xsl:template match="BK"> <xsl:value-of select="$vNL"/> <xsl:apply-templates/> </xsl:template>
这对于匹配CL的模板也是有效的 – 它可以替换为:
<xsl:template match="CL"> <xsl:apply-templates/> </xsl:template>
最后,可以完全删除此模板,因为它完全复制了与任何元素匹配的XSLT内置模板.
因此,这些重构后的转换是:
<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:variable name="vNL" select="'
'"/> <xsl:template match="/"> <root> <story> <xsl:apply-templates select="root/story/CL"/> </story> </root> </xsl:template> <xsl:template match="CityDescription | CompanyName | address"> <xsl:element name="{name()}"> <xsl:value-of select="."/> </xsl:element> </xsl:template> <xsl:template match="BK"> <xsl:value-of select="$vNL"/> <xsl:apply-templates/> </xsl:template> <xsl:template match="HoldingCo"> <HoldingCo> <xsl:text>Holding Co: </xsl:text> <xsl:value-of select="."/> </HoldingCo> </xsl:template> <xsl:template match="TotalAssets"> <TotalAssets> <xsl:text>Total Assets: </xsl:text> <xsl:value-of select="."/> </TotalAssets> </xsl:template> <xsl:template match="TotalLiabilities"> <TotalLiabilities> <xsl:text>Total Liabilities: </xsl:text> <xsl:value-of select="."/> </TotalLiabilities> </xsl:template> <xsl:template match="TotalDeposits"> <TotalDeposits> <xsl:text>Total Deposits: </xsl:text> <xsl:value-of select="."/> </TotalDeposits> </xsl:template> <xsl:template match="EquityCapital"> <EquityCapital> <xsl:text>Total Assets: </xsl:text> <xsl:value-of select="."/> </EquityCapital> </xsl:template> <xsl:template match="text()"/> </xsl:stylesheet>
说明:
说明:
<xsl:apply-templates select="someChildName"/>
如果存在someChildName子节点,则仅应用模板(执行处理).
