如何使用xsl将cdata添加到xml文件 [英] how to add cdata to an xml file using xsl
本文介绍了如何使用xsl将cdata添加到xml文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我正在尝试将CDATA封装为xml文件中的元素.
I am trying to wrap CDATA for the elements in an xml file.
我想念的另一点是，有些元素具有相同的名称，需要避免添加CDATA.
Another point i missed was, there are some elements with same names those need to be escaped from adding CDATA.
这是源xml文件:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books>
<jndi:binding name="books/cat/action/configs">
<jndi:value type="java.lang.String">
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/romance/configs">
<jndi:value type="java.lang.String">
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/thriller/configs">
<jndi:value type="java.lang.String">
abc.com
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/classic/configs">
<jndi:value type="java.lang.String">
abc.com
</jndi:value>
</jndi:binding>
</books>
I have tried to use the same trick that @Dimitre Novatchev has mentioned here at How to insert CDATA into XML text markup exported from Access 2003?. But some how that's not working for me.
这是我尝试过的xsl文件:
This is the xsl file that i tried:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet
version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:jndi="urn:jboss:jndi-binding-service:1.0" >
<xsl:strip-space elements="*"/>
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="node()|@*"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
有人可以建议我如何将CDATA添加到元素，还需要添加另一行<?xml version ="1.0" encoding ="ISO-8859-1"吗?> 在CDATA的开头.
Can some one suggest me how to add CDATA to an element and also need to add an additional line <?xml version="1.0" encoding="ISO-8859-1"?> at the beginning of CDATA.
这是预期的结果:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books>
<jndi:binding name="books/cat/action/configs">
<jndi:value type="java.lang.String">
<![CDATA[
<?xml version="1.0" encoding="ISO-8859-1"?>
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
]]>
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/romance/configs">
<jndi:value type="java.lang.String">
<![CDATA[
<?xml version="1.0" encoding="ISO-8859-1"?>
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
]]>
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/thriller/configs">
<jndi:value type="java.lang.String">
abc.com
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/classic/configs">
<jndi:value type="java.lang.String">
abc.com
</jndi:value>
</jndi:binding>
</books>
推荐答案
问题是您需要将 CDATA 部分中包含的XML转换为文本.该XSLT应该可以完成此任务:
The problem is that you need to convert the XML that goes inside the CDATA sections into text. This XSLT should do the job:
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:jndi="urn:jboss:jndi-binding-service:1.0">
<xsl:output method="xml" indent="yes" cdata-section-elements="jndi:value"/>
<xsl:template match="jndi:value">
<xsl:copy>
<!-- Copy the attributes -->
<xsl:apply-templates select="@*"/>
<!-- Convert the contained nodes (elements and text) into text -->
<xsl:variable name="subElementsText">
<xsl:apply-templates select="node()" mode="asText"/>
</xsl:variable>
<!-- Output the XML directive and the converted nodes -->
<xsl:value-of select="concat('<?xml version="1.0" encoding="utf-8"?>',$subElementsText)"/>
</xsl:copy>
</xsl:template>
<!-- Copy text nodes as text -->
<xsl:template match="text()" mode="asText">
<xsl:copy/>
</xsl:template>
<!-- Copy elements as text -->
<xsl:template match="*" mode="asText">
<xsl:value-of select="concat('<',name())"/>
<xsl:for-each select="@*">
<xsl:value-of select="concat(' ',name(),'="',.,'"')"/>
</xsl:for-each>
<xsl:value-of select="'>'"/>
<xsl:apply-templates select="node()" mode="asText"/>
<xsl:value-of select="concat('</',name(),'>')"/>
</xsl:template>
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
基本上，它使用几个模板来匹配需要转换为文本并手动"转换的XML元素.其余的操作由 cdata-sections-elements 指令完成.
Basically it uses a couple of templates to match the XML elements that need to be converted to text and convert them 'manually'. The cdata-sections-elements directive does the rest.
应用于
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<books xmlns:jndi="urn:jboss:jndi-binding-service:1.0">
<jndi:binding name="books/cat/action/configs">
<jndi:value type="java.lang.String">
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
</jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/romance/configs">
<jndi:value type="java.lang.String">
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"/>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
</jndi:value>
</jndi:binding>
</books>
产生预期的结果:
<?xml version="1.0" encoding="utf-8"?>
<books xmlns:jndi="urn:jboss:jndi-binding-service:1.0">
<jndi:binding name="books/cat/action/configs">
<jndi:value type="java.lang.String"><![CDATA[<?xml version="1.0" encoding="utf-8"?>
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"></defaults>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
]]></jndi:value>
</jndi:binding>
<jndi:binding name="books/cat/romance/configs">
<jndi:value type="java.lang.String"><![CDATA[<?xml version="1.0" encoding="utf-8"?>
<urlConfig>
<defaults catID="1983" subcatID="1987" method="get" onError="keep"></defaults>
<urlKey name="logo" altURL="def.com">
<address>abc.com</address>
</urlKey>
<urlKey name="logo1" altURL="def.com">
<address>abc.com</address>
</urlKey>
</urlConfig>
]]></jndi:value>
</jndi:binding>
