Question

我得到了一个XML，我将其转换为另一个，但在翻译之后，我得到了一些具有空命名空间声明（xmlns=""）的元素，我想删除它。

其次，我还希望在xmlns:xsi元素中声明InterChangeHead。

INPUT XML

<?xml version="1.0" encoding="UTF-8"?>

有人可以帮我解决最后一点吗？我添加了下一个模板，因为我认为这将删除空命名空间声明：

<!-- Copy local names -->
<xsl:template match="*">
    <xsl:element name="{name()}">
        <xsl:apply-templates select="@*|node()" />
    </xsl:element>
</xsl:template>

Answer 1

请记住，xmlns="..."声明为其附加的元素及其所有后代设置默认命名空间，除非在树的另一个xmlns="..."处反对。因此，在您想要的输出中，<InterChangeHead xmlns="posten.xsd" >下的所有后代元素也位于posten.xsd命名空间中，您的模板需要反映这一点。由于您使用的是XSLT 2.0，因此您可以使用条件作为XPath表达式的一部分来轻松完成此任务：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

    <!-- Copy elements, fixing up names and namespaces as required -->
    <xsl:template match="*">
        <xsl:element name="{if(substring(local-name(), 1, 2) = 'he')
                            then substring(local-name(), 3) else local-name()}"
                     namespace="{if(ancestor-or-self::InterChangeHead)
                                 then 'posten.xsd' else ''}">
            <xsl:apply-templates select="@*|node()" />
        </xsl:element>
    </xsl:template>

    <!-- specific template for InterChangeHead to add the (unused) xsi
         namespace declaration -->
    <xsl:template match="InterChangeHead">
      <InterChangeHead xmlns="posten.xsd"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
        <xsl:apply-templates select="@*|node()" />
      </InterChangeHead>
    </xsl:template>

    <xsl:template match="@* | text()">
      <xsl:copy-of select="." />
    </xsl:template>

    <!-- Remove type attribute -->
    <xsl:template match="@type"/>

    <!-- Remove unnecessary elements -->
    <xsl:template match="heXmlnsxsi" />
    <xsl:template match="heXmlns" />
</xsl:stylesheet>

我添加了一个特定的模板来在xsi上声明InterChangeHead命名空间，虽然我不确定为什么必须包含该声明，因为它未在输出XML文档中的任何位置使用。如果结果没有必要，您可以完全删除<xsl:template match="InterChangeHead">，因为匹配*的模板也会处理InterChangeHead，正确设置名称空间。

您需要更改每个元素节点的名称空间，因此请更改模板

<!-- Correct InterChangeHead element -->
<xsl:template match="InterChangeHead">
    <xsl:element name="InterChangeHead" namespace="posten.xsd">     
        <!-- Copy childs -->
        <xsl:apply-templates select="child::node()" />
    </xsl:element>
</xsl:template>

到

<!-- Correct InterChangeHead element and descendants -->
<xsl:template match="InterChangeHead | InterChangeHead//*">
    <xsl:element name="{local-name()}" namespace="posten.xsd">     
        <!-- Copy childs -->
        <xsl:apply-templates select="@* | node()" />
    </xsl:element>
</xsl:template>

这是一个简化代码的完整样式表：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:fn="http://www.w3.org/2005/xpath-functions" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" exclude-result-prefixes="xs fn">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

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

    <!-- Correct InterChangeHead element -->
    <xsl:template match="InterChangeHead | InterChangeHead//*">
        <xsl:element name="{local-name()}" namespace="posten.xsd">     
            <!-- Copy childs -->
            <xsl:apply-templates select="@* | node()" />
        </xsl:element>
    </xsl:template>

    <!-- Rename elements beginning with "he" to elements without the "he" -->
    <xsl:template match="InterChangeHead//*[substring(local-name(), 1, 2) = 'he']" priority="5">
                <xsl:element name="{substring(local-name(), 3)}" namespace="posten.xsd">
                    <xsl:apply-templates select="@*|node()" />
                </xsl:element>
    </xsl:template>

    <!-- Remove type attribute -->
    <xsl:template match="@type"/>

    <!-- Remove unnecessary elements -->
    <xsl:template match="heXmlnsxsi" priority="6"/>
    <xsl:template match="heXmlns" priority="6"/>
</xsl:stylesheet>
