Python: How do you get an XML element's text content using xml.dom.minidom?
提问by mindthief
I've called elems = xmldoc.getElementsByTagName('myTagName')on an XML object that I parsed as minidom.parse(xmlObj). Now I'm trying to get the text content of this element, and although I spent a while looking through the dir() and trying things out, I haven't found the call yet. As an example of what I want to accomplish, in:
我调用elems = xmldoc.getElementsByTagName('myTagName')了一个 XML 对象，我将其解析为minidom.parse(xmlObj). 现在我正在尝试获取该元素的文本内容，虽然我花了一段时间查看 dir() 并尝试了一些东西，但我还没有找到调用。作为我想要完成的一个例子，在：
<myTagName> Hello there </myTagName>
<myTagName> Hello there </myTagName>
I would like the extract just "Hello there". (obviously I could parse this myself but I expect there is some built-in functionality)
我想要摘录只是“你好”。（显然我可以自己解析，但我希望有一些内置功能）
Thanks
谢谢

Try like this:
像这样尝试：
xmldoc.getElementsByTagName('myTagName')[0].firstChild.nodeValue

for elem in elems:
print elem.firstValue.nodeValue
That will print out each myTagName's text.
这将打印出每个 myTagName 的文本。

wait a mo... do you want ALL the text under a given node? It has then to involve a subtree traversal function of some kind. Doesn't have to be recursive but this works fine:
等一下...你想要给定节点下的所有文本吗？然后它必须涉及某种类型的子树遍历函数。不必是递归的，但这工作正常：
def get_all_text( node ):
if node.nodeType == node.TEXT_NODE:
return node.data
else:
text_string = ""
for child_node in node.childNodes:
text_string += get_all_text( child_node )
return text_string
