How can I strip namespaces out of an lxml tree?

跟風遠走 提交于 2019-11-28 08:46:16
Following on from Removing child elements in XML using python ... Thanks to @Tichodroma, I have this code: If you can use lxml , try this: import lxml.etree tree = lxml.etree.parse("leg.xml") for dog in tree.xpath("//Leg1:Dog", namespaces={"Leg1": "http://what.not"}): parent = dog.xpath("..")[0] parent.remove(dog) parent.text = None tree.write("leg.out.xml") Now leg.out.xml looks like this: <?xml version="1.0"?> <Leg1:MOR xmlns:Leg1="http://what.not" oCount="7"> <Leg1:Order> <Leg1:CTemp id="FO"> <Leg1:Group bNum="001" cCount="4"/> <Leg1:Group bNum="002" cCount="4"/> </Leg1:CTemp> <Leg1:CTemp

I am preparing for an exam where i couldn't understand the convertion of infix notation to polish notation for the below expression: (a–b)/c*(d + e – f / g) Can any one tell step by step how the given expression will be converted to prefix? rajdip Algorithm ConvertInfixtoPrefix Purpose: Convert an infix expression into a prefix expression. Begin // Create operand and operator stacks as empty stacks.

Difference between http://+:8080/ and http://*:8080/

问题 What are the differences between these two prefixes in terms of HttpListener or any other? http://+:8080/ http://*:8080/ 回答1: http://*:8080/ : Receive all HTTP requests on port 8080 that are not already being handled by some other HttpListener . http://+:8080/ : Receive all HTTP requests on port 8080 even if they're already handled by another HttpListener . 回答2: In addition to @Paulpro's great answer, the link posted by @rownage (see this answer) provides some more information about the

Why does the postfix increment operator take a dummy parameter?

不问归期 提交于 2019-11-28 06:25:10
Have a look at these function signatures: class Number { public: Number& operator++ (); // prefix ++ Number operator++ (int); // postfix ++ }; Prefix doesn't take any parameter but postfix does. Why? I thought we can recognize them with different return types. Prefix and postfix ++ are different operators. With the standard Foo operator symbol(Foo &) style declaration there was no obvious way to distinguish the two. Rather than come up with some new syntax like Foo symbol operator(Foo &) which would make it into a special case unlike all the other operators and likely a bit of a pain to parse,

Precedence of ++ and — operators in Java

旧城冷巷雨未停 提交于 2019-11-28 03:12:36
问题 I read from the official tutorial of Java that prefix and postfix ++ -- have different precedences: postfix: expr++ expr-- unary: ++expr --expr +expr -expr ~ ! Operators According to the tutorial, shouldn't this d = 1; System.out.println(d++ + ++d); print out 6 ( d++ makes d 2, ++d makes it 3) instead of 4? I know the explanation of ++d being evaluated beforehand, but if d++ has higher precedence then ++d , why isn't d++ being first evaluated? And what is more, in what case should d++ shows

nvm is not compatible with the npm config “prefix” option:

别等时光非礼了梦想. 提交于 2019-11-28 02:41:09
I am trying to run another NodeJS version with nvm but getting this error: $ nvm use v4.2.4 nvm is not compatible with the npm config "prefix" option: currently set to "/Users/z/.npm-global" Run `npm config delete prefix` or `nvm use --delete-prefix v4.2.4` to unset it. I have my prefix set on purpose to avoid sudo npm (see https://docs.npmjs.com/getting-started/fixing-npm-permissions ). Is there any way I can use nvm without losing my prefix for globally installed packages? Mick Delete and Reset the prefix $ npm config delete prefix $ npm config set prefix $NVM_DIR/versions/node/v6.11.1 Note:

How to circumvent the fallacy of Python's os.path.commonprefix?

随声附和 提交于 2019-11-28 02:34:29
问题 My problem is to find the common path prefix of a given set of files. Literally I was expecting that "os.path.commonprefix" would do just that. Unfortunately, the fact that commonprefix is located in path is rather misleading, since it actually will search for string prefixes. The question to me is, how can this actually be solved for paths? The issue was briefly mentioned in this (fairly high rated) answer but only as a side-note and the proposed solution (appending slashes to the input of

PHP5 calculate IPv6 range from cidr prefix?

对着背影说爱祢 提交于 2019-11-28 01:59:20
I am able to do this with IPv4 using code snippets from various online sources. I was wondering if there was a way to do it with IPv6. Basically I just need a form that I can enter an IPv6 address and prefix (ex: address/68) and it calculates the network address, first useable address, last useable address, and broadcast address. Then just prints to screen. Not looking to store it in a database or anything yet. How would I go about doing this? Thanks to everyone in advance! First of all: IPv6 doesn't have network and broadcast addresses. You can use all addresses in a prefix. Second: On a LAN
