我正在尝试使用xsl从xml中删除一些元素,并尝试从sub1元素中声明的更改命名空间值。问题是,当我更改名称空间值时,旧的名称空间声明被插入到子元素(示例中的sub2)中,如何更改代码以防止它?
我做了这个例子,因为我无法显示真实的代码
的test.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet version="1.0" href="test.xsl"?>
<lamp:rootElement xmlns:lamp="adgfdgfhdsadfse">
<pref:sub1 ID="someId" xmlns:pref="http://www.myMountain.org/blabla">
<pref:sub2>
Today is tuesday
<pref:sub3 att="someAttribute">
Some text
<pref:sub4>
<pref:emptyElement/>
</pref:sub4>
</pref:sub3>
</pref:sub2>
</pref:sub1>
</lamp:rootElement>
test.xsl
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:oldPref="http://www.myMountain.org/blabla"
xmlns:pref="http://www.myHill.org/blabla"
exclude-result-prefixes="oldPref">
<!-- For deleting element "sub4" -->
<xsl:template match="oldPref:sub1/oldPref:sub2/oldPref:sub3/oldPref:sub4"/>
<!-- Now i'm replacing the value of "pref" namespace (by creating a new element) -->
<xsl:template match="oldPref:sub1">
<pref:sub1>
<!-- Now i'm copying the elements from old "sub1" to the new one -->
<xsl:apply-templates select="@*|node()"/>
</pref:sub1>
</xsl:template>
<!-- Now im copying the rest of the xml file -->
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
错误的结果是我得到了result.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet version="1.0" href="test.xsl"?>
<lamp:rootElement xmlns:lamp="adgfdgfhdsadfse">
<pref:sub1 xmlns:pref="http://www.myHill.org/blabla" ID="someId">
<pref:sub2 xmlns:pref="http://www.myMountain.org/blabla">
Today is tuesday
<pref:sub3 att="someAttribute">
Some text
</pref:sub3>
</pref:sub2>
</pref:sub1>
</lamp:rootElement>
期望的结果
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet version="1.0" href="test.xsl"?>
<lamp:rootElement xmlns:lamp="adgfdgfhdsadfse">
<pref:sub1 xmlns:pref="http://www.myHill.org/blabla" ID="someId">
<pref:sub2>
Today is tuesday
<pref:sub3 att="someAttribute">
Some text
</pref:sub3>
</pref:sub2>
</pref:sub1>
</lamp:rootElement>
我的撒克逊人
Manifest-Version: 1.0
Ant-Version: Apache Ant 1.9.4
Project-Name: Saxon-HE
Created-By: 1.7.0_05-b06 (Oracle Corporation)
Main-Class: net.sf.saxon.Transform
这是我正在使用的命令
java net.sf.saxon.Transform -s:test.xml -xsl:test.xsl -o:result.xml
答案 0 :(得分:1)
这里的问题是您要更改pref:sub1
上的命名空间,而不是任何其他pref:
元素上的命名空间。你需要更通用的东西:
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:oldPref="http://www.myMountain.org/blabla"
xmlns:pref="http://www.myHill.org/blabla"
exclude-result-prefixes="oldPref">
<xsl:template match="node()|@*">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="oldPref:*">
<xsl:element name="pref:{local-name()}">
<xsl:apply-templates select="@*|node()"/>
</xsl:element>
</xsl:template>
<xsl:template match="oldPref:sub4" />
</xsl:stylesheet>
在样本输入上运行时,结果为:
<?xml-stylesheet version="1.0" href="test.xsl"?>
<lamp:rootElement xmlns:lamp="adgfdgfhdsadfse">
<pref:sub1 ID="someId" xmlns:pref="http://www.myHill.org/blabla">
<pref:sub2>
Today is tuesday
<pref:sub3 att="someAttribute">
Some text
</pref:sub3>
</pref:sub2>
</pref:sub1>
</lamp:rootElement>
