我正在构建openoffice文档。我有一个脚手架,用于生成我的content.xml文件。 content-scaffold.xml文件存储在filesystem中,如下所示:
<?xml version="1.0" encoding="UTF-8"?>
<office:document-content
xmlns:anim="urn:oasis:names:tc:opendocument:xmlns:animation:1.0"
xmlns:chart="urn:oasis:names:tc:opendocument:xmlns:chart:1.0"

office:version="1.2">
<office:automatic-styles>
<style:style style:family="text" style:name="Strong">
<style:text-properties
fo:color="#000000"
fo:font-weight="bold" />
</style:style>
</office:automatic-styles>
<office:body>
<office:text>
<!-- content will go here -->
</office:text>
</office:body>
</office:document-content>
我的想法是,我将这个xml并注入office:text标签(在python中),然后将其渲染回来。在这个例子中,我注入了一个简单的文本:p tag。
document_content = ElementTree.parse('content-scaffold.xml').getroot()
office_body = document_content.find('office:body', NAMESPACES)
office_text = office_body.find('office:text', NAMESPACES)
p = ElementTree.SubElement(office_text, 'text:p')
p.text = "Hello"
但是,这就是命名空间声明在呈现后的样子:
<office:document-content
xmlns:fo="urn:oasis:names:tc:opendocument:xmlns:xsl-fo-compatible:1.0"
xmlns:office="urn:oasis:names:tc:opendocument:xmlns:office:1.0"
xmlns:style="urn:oasis:names:tc:opendocument:xmlns:style:1.0"
office:version="1.2">
这会导致以下错误:
p上的命名空间前缀文本未定义
很明显,ElementTree只保留所需的xmlns声明(在我的情况下,办公室和样式,因为它们是content-scaffold.xml中唯一存在的声明),并且它是很简约。但是,我真的想要它们,以便能够使用所有名称空间。
知道如何强制ElementTree保留它们吗?或者我从一开始就认为这是错的?我对任何其他解决方案持开放态度。
注意:我使用的是Python 3和ElementTree

ElementTree在命名空间处理方面相当薄弱。但是,你要求的是什么(但这有点麻烦):
from xml.etree import ElementTree as ET
NAMESPACES = {"anim": "urn:oasis:names:tc:opendocument:xmlns:animation:1.0",
"chart": "urn:oasis:names:tc:opendocument:xmlns:chart:1.0",
"config": "urn:oasis:names:tc:opendocument:xmlns:config:1.0",
"db": "urn:oasis:names:tc:opendocument:xmlns:database:1.0",
"dc": "http://purl.org/dc/elements/1.1/",
"dr3d": "urn:oasis:names:tc:opendocument:xmlns:dr3d:1.0",
"draw": "urn:oasis:names:tc:opendocument:xmlns:drawing:1.0",
"fo": "urn:oasis:names:tc:opendocument:xmlns:xsl-fo-compatible:1.0",
"form": "urn:oasis:names:tc:opendocument:xmlns:form:1.0",
"grddl": "http://www.w3.org/2003/g/data-view#",
"manifest": "urn:oasis:names:tc:opendocument:xmlns:manifest:1.0",
"math": "http://www.w3.org/1998/Math/MathML",
"meta": "urn:oasis:names:tc:opendocument:xmlns:meta:1.0",
"number": "urn:oasis:names:tc:opendocument:xmlns:datastyle:1.0",
"odf": "http://docs.oasis-open.org/ns/office/1.2/meta/odf#",
"of": "urn:oasis:names:tc:opendocument:xmlns:of:1.2",
"office": "urn:oasis:names:tc:opendocument:xmlns:office:1.0",
"pkg": "http://docs.oasis-open.org/ns/office/1.2/meta/pkg#",
"presentation": "urn:oasis:names:tc:opendocument:xmlns:presentation:1.0",
"script": "urn:oasis:names:tc:opendocument:xmlns:script:1.0",
"smil": "urn:oasis:names:tc:opendocument:xmlns:smil-compatible:1.0",
"style": "urn:oasis:names:tc:opendocument:xmlns:style:1.0",
"svg": "urn:oasis:names:tc:opendocument:xmlns:svg-compatible:1.0",
"table": "urn:oasis:names:tc:opendocument:xmlns:table:1.0",
"text": "urn:oasis:names:tc:opendocument:xmlns:text:1.0",
"xforms": "http://www.w3.org/2002/xforms",
"xhtml": "http://www.w3.org/1999/xhtml",
"xlink": "http://www.w3.org/1999/xlink"}
document_content = ET.parse('content-scaffold.xml').getroot()
office_body = document_content.find('office:body', NAMESPACES)
office_text = office_body.find('office:text', NAMESPACES)
p = ET.SubElement(office_text, 'text:p')
p.text = "Hello"
for prefix, uri in NAMESPACES.items():
ET.register_namespace(prefix, uri) # Ensure correct prefixes in output
if prefix not in ("office", "fo", "style"): # Prevent duplicate ns declarations
document_content.set("xmlns:" + prefix, uri) # Add ns declarations to root element
ET.ElementTree(document_content).write("output.xml")
此代码将创建一个保留所有名称空间声明的结果文档。
以下是使用lxml:
的方法from lxml import etree as ET
NAMESPACES = {"office": "urn:oasis:names:tc:opendocument:xmlns:office:1.0"}
document_content = ET.parse('content-scaffold.xml')
office_body = document_content.find('office:body', NAMESPACES)
office_text = office_body.find('office:text', NAMESPACES)
p = ET.SubElement(office_text, '{urn:oasis:names:tc:opendocument:xmlns:text:1.0}p')
p.text = "Hello"
document_content.write("output.xml")
请注意,您必须使用SubElement()
中的Clark notation提供元素名称。
