抑制 XML 文件中的命名空间前缀

Suppressing namespace prefix in XML file

输入文件:

<?xml version="1.0" encoding="utf-8"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
    <Default Extension="json" ContentType=""/>
    <Override PartName="/Version" ContentType=""/>
</Types>

我得到的输出:

<?xml version='1.0' encoding='utf-8'?>
<xmlns:Types xmlns:xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
    <xmlns:Default Extension="json" ContentType=""/>
    <xmlns:Override PartName="/Version" ContentType=""/>
    <xmlns:Default Extension="png" ContentType=""/>
</xmlns:Types>

要求输出:

<?xml version="1.0" encoding="utf-8"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
    <Default Extension="json" ContentType=""/>
    <Override PartName="/Version" ContentType=""/>
    <Default Extension="png" ContentType=""/>
</Types>

我使用以下行添加了默认标签,该标签具有以“png”作为值的扩展属性。添加上述标签命名空间时,会添加到每个标签中。我是 Python、XML 处理的新手。我试过这个:

import xml.etree.ElementTree as ET
def formatxml():
    dest="input.xml"
    tree = ET.parse(dest)
    root = tree.getroot()
    ET.register_namespace('xmlns',"http://schemas.openxmlformats.org/package/2006/content-types")
    child=ET.SubElement(root,"{http://schemas.openxmlformats.org/package/2006/content- types}Default")
    child.set('Extension',"png")
    child.set('ContentType',"")
    tree.write(dest,xml_declaration=True,encoding='utf-8',method="xml")

下面是如何使用 XSLT 完成任务。

XSLT 遵循所谓的身份转换 模式。

输入XML

<?xml version="1.0" encoding="utf-8"?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
    <Default Extension="json" ContentType=""/>
    <Override PartName="/Version" ContentType=""/>
</Types>

XSLT

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns1="http://schemas.openxmlformats.org/package/2006/content-types" exclude-result-prefixes="ns1">
    <xsl:output method="xml" encoding="utf-8" indent="yes" omit-xml-declaration="no"/>
    <xsl:strip-space elements="*"/>

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

    <xsl:template match="ns1:Override">
        <xsl:copy-of select="."/>
        <Default Extension="png" ContentType=""/>
    </xsl:template>
</xsl:stylesheet>

输出XML

<?xml version='1.0' encoding='utf-8' ?>
<Types xmlns="http://schemas.openxmlformats.org/package/2006/content-types">
  <Default Extension="json" ContentType=""/>
  <Override PartName="/Version" ContentType=""/>
  <Default Extension="png" ContentType=""/>
</Types>

register_namespace() 设置序列化 XML 时使用的前缀。由于您不需要任何前缀,因此请使用空字符串。

你只需要改变

ET.register_namespace('xmlns',"http://schemas.openxmlformats.org/package/2006/content-types")` 

ET.register_namespace('',"http://schemas.openxmlformats.org/package/2006/content-types")
