问题描述
我有这个xml模型。
因此,我必须在该文件中添加一些节点(请参见注释文本)。
我该怎么做?
So I have to add some node (see the text commented) to this file.How I can do it?
我已经写了这个部分代码,但是它不起作用:
I have writed this partial code but it doesn't work:
xmldoc=minidom.parse(directory)
child = xmldoc.createElement("map")
for node in xmldoc.getElementsByTagName("Environment"):
node.appendChild(child)
预先感谢。
推荐答案
我下载了示例XML文件,并且您的代码运行正常。您的问题很可能与以下行有关: xmldoc = minidom.parse(directory)
,这不应该是您尝试解析的文件而不是目录的路径吗? parse()
函数解析一个XML文件,它不自动解析给定目录中的所有XML文件。
I downloaded your sample xml file and your code works fine. Your problem is most likely with the line: xmldoc=minidom.parse(directory)
, should this not be the path to the file you are trying to parse not to a directory? The parse()
function parses an XML file it does not automatically parse all the XML files in a given directory.
如果将代码更改为以下代码,则应该可以正常工作:
If you change your code to something like below this should work fine:
xmldoc=minidom.parse("directory/model_template.xml")
child = xmldoc.createElement("map")
for node in xmldoc.getElementsByTagName("Environment"):
node.appendChild(child)
如果然后执行以下语句: print xmldoc.toxml()
,您会看到 map
元素确实已添加到 Environment
元素:< Environment>< map />< / Environment>
。
If you then execute the statement: print xmldoc.toxml()
you will see that the map
element has indeed been added to the Environment
element: <Environment><map/></Environment>
.
