问题 I have this kind of XML structure (output from the Esprima ASL converted from JSON), it can get even more nested than this ( ASL.xml ): <?xml version="1.0" encoding="UTF-8" ?> <program> <type>Program</type> <body> <type>VariableDeclaration</type> <declarations> <type>VariableDeclarator</type> <id> <type>Identifier</type> <name>answer</name> </id> <init> <type>BinaryExpression</type> <operator>*</operator> <left> <type>Literal</type> <value>6</value> </left> <right> <type>Literal</type> <value

Get node name with minidom

由 感情迁移 提交于 2019-12-05 03:05:52
Is it possible to get the name of a node using minidom? For example I have a node: <heading><![CDATA[5 year]]></heading> What I'm trying to do, is store the value heading so that I can use it as a key in a dictionary. The closest I can get is something like: [<DOM Element: heading at 0x11e6d28>] I'm sure I'm overlooking something very simple here, thanks. Is this what you mean? tag= node.tagName d[tag]= node tagName is defined in DOM Level 1 Core, the basic standard that minidom (mostly) implements. 来源： https://stackoverflow.com/questions/2795462/get-node-name-with-minidom

问题 I am using XML minidom (xml.dom.minidom) in Python, but any error in the XML will kill the parser. Is it possible to ignore them, like a browser for example? I am trying to write a browser in Python, but it just throws an exception if the tags aren't fully compatible. 回答1: There is a library called BeautifulSoup, I think it's what you're looking for. As you're trying to parse a invalid XML, the normal XML parser won't work. BeautifulSoup is more fail-tolerant, it can still extract information
