[英]Include one XML within another XML and parse it with python
I wanted to include an XML file in another XML file and parse it with python.我想在另一个 XML 文件中包含一个 XML 文件,并用 python 解析它。 I am trying to achieve it through Xinclude.
我正在尝试通过 Xinclude 来实现它。 There is a file1.xml which looks like
有一个 file1.xml 看起来像
<?xml version="1.0"?>
<root>
<document xmlns:xi="http://www.w3.org/2001/XInclude">
<xi:include href="file2.xml" parse="xml" />
</document>
<test>some text</test>
</root>
and file2.xml which looks like和 file2.xml 看起来像
<para>This is a paragraph.</para>
Now in my python code i tried to access it like:现在在我的 python 代码中,我尝试像这样访问它:
from xml.etree import ElementTree, ElementInclude
tree = ElementTree.parse("file1.xml")
root = tree.getroot()
for child in root.getchildren():
print child.tag
It prints the tag of all child elements of root它打印根的所有子元素的标签
document
test
Now when i tries to print the child objects directly like现在,当我尝试直接打印子对象时
print root.document
print root.test
It says the root doesnt have children named test or document.它说根没有名为 test 或 document 的子级。 Then how am i suppose to access the content in file2.xml?
那么我想如何访问 file2.xml 中的内容?
I know that I can access the XML elements from python with schema like:我知道我可以使用如下架构从 python 访问 XML 元素:
schema=etree.XMLSchema(objectify.fromstring(configSchema))
xmlParser = objectify.makeparser(schema = schema)
cfg = objectify.fromstring(xmlContents, xmlParser)
print cfg.elemetName # access element
But since here one XML file is included in another, I am confused how to write the schema.但是由于这里一个 XML 文件包含在另一个文件中,我很困惑如何编写架构。 How can i solve it?
我该如何解决?
Below以下
import xml.etree.ElementTree as ET
xml1 = '''<?xml version="1.0"?>
<root>
<test>some text</test>
</root>'''
xml2 = '''<para>This is a paragraph.</para>'''
root1 = ET.fromstring(xml1)
root2 = ET.fromstring(xml2)
root1.insert(0,root2)
para_value = root1.find('.//para').text
print(para_value)
output output
This is a paragraph.
Not sure why you want to use XInclude, but including an XML file in another one is a basic mechanism of SGML and XML, and can be achieved without XInclude as simple as:不知道为什么要使用 XInclude,但在另一个文件中包含 XML 文件是 SGML 和 XML 的基本机制,并且可以在没有 XInclude 的情况下实现,如下所示:
<!DOCTYPE root [
<!ENTITY externaldoc SYSTEM "file2.xml">
]>
<root>
<document>
&externaldoc;
</document>
<test>some text</test>
</root>
