PHP: How to replace existing XML node with XMLWriter

I am editing an XML file and need to populate it with data from a database. DOM works but it is unable to scale to several hundreds of MBs so I am now using XMLReader and XMLWriter which can write the very large XML file. Now, I need to select a node and add children to it but I can't find a method to do it, can someone help me out? I can find the node I need to add children to by: if ($

PHP:如何用XMLWriter替换现有的XML节点

我正在编辑一个XML文件,需要用数据库中的数据填充它。 DOM可以工作,但无法扩展到几百MB,因此我现在使用XMLReader和XMLWriter来编写非常大的XML文件。 现在,我需要选择一个节点并添加孩子,但我找不到一个方法来完成它,有人可以帮我吗? 我可以通过以下方式找到我需要添加孩子的节点: if ($xmlReader->nodeType == XMLReader::ELEMENT && $xmlReader->name == 'data') { echo 'data was foun

XmlWriter comlex usage with a XmlReader

I im going to read file by xmlReader and insert a child elements into this object by XmlWriter and save the output. How i can parse data between this two classes? I know that SimpleXml is already exists and makes it easy. but i have a huge amount of the data and i need to make it faster then SimpleXml can. It is only teory and i havnt code yet, i need only to get answer only by these qwestion

使用XmlReader的XmlWriter comlex用法

我即将通过xmlReader读取文件,并通过XmlWriter向此对象中插入一个子元素并保存输出。 我如何解析这两个类之间的数据? 我知道SimpleXml已经存在并且很容易。 但我有大量的数据,我需要使其更快,然后SimpleXml可以。 它仅仅是条件性的,我还有代码,我只需要通过这些qwestions得到答案:创建两个对象reader / writer和他们的工作通过SimpleXml更快的类似吗? 如何使用xmlReader对象并将数据部分解析到XmlWriter中? XMLW

Is XMLReader a SAX parser, a DOM parser, or neither?

I am testing various methods to read (possibly large, with very frequent reads) XML configuration files in PHP. No writing is ever needed. I have two successful implementations, one using SimpleXML (which I know is a DOM parser) and one using XMLReader . I know that a DOM reader must read the whole tree and therefore uses more memory. My tests reflect that. I also know that A SAX parser is

XMLReader是SAX解析器,DOM解析器还是两者都不是?

我正在测试各种方法来读取PHP中的XML配置文件(可能很大,读取频率很高)。 不需要写作。 我有两个成功的实现,一个使用SimpleXML (我知道它是一个DOM解析器),一个使用XMLReader 。 我知道DOM阅读器必须阅读整个树,因此需要更多的内存。 我的测试反映了。 我也知道SAX解析器是一个“基于事件”的解析器,它使用更少的内存,因为它从流中读取每个节点而不检查下一步是什么。 XMLReader也可以使用游标读取数据流,并提供

Does AMD's OpenCL offer something similar to CUDA's GPUDirect?

NVIDIA offers GPUDirect to reduce memory transfer overheads. I'm wondering if there is a similar concept for AMD/ATI? Specifically: 1) Do AMD GPUs avoid the second memory transfer when interfacing with network cards, as described here. In case the graphic is lost at some point, here is a description of the impact of GPUDirect on getting data from a GPU on one machine to be transferred ac

AMD的OpenCL是否提供类似于CUDA的GPUDirect?

NVIDIA提供GPUDirect以减少内存传输开销。 我想知道AMD / ATI是否有类似的概念? 特别: 1)如此处所述,AMD GPU是否在与网卡连接时避免第二次内存传输。 如果图形在某个时候丢失了,下面描述GPUDirect从一台机器上的GPU获取数据以通过网络接口传输的影响:使用GPUDirect,GPU内存转到主机内存然后直接传输到网络接口卡。 如果没有GPUDirect,GPU内存会在一个地址空间中进入主机内存,那么CPU必须执行一次副本才能将内存移

How to keep your tests small while using data providers?

I am testing the endpoints/API of a web application. I have multiple small tests that depend on the return values of the preceding tests. Some of the tests even depend on side effects that are made by the preceding tests. Here's an example of how it goes (the numbered list items represent individual test cases): Make a request to an endpoint and assert the http code is 200, return the re

如何在使用数据提供者时保持较小的测试?

我正在测试Web应用程序的端点/ API。 我有多个小测试,取决于前面测试的返回值。 一些测试甚至依赖于前面测试所产生的副作用。 下面是一个例子(编号列表项代表单个测试用例): 向端点发出请求并声明http代码为200,返回响应 解析响应主体并对其做一些断言,返回解析的响应主体 对解析的响应主体的调试值做一些断言 向另一个端点发出新请求并声明http代码为200,返回响应 解析响应主体并断言来自测试1的副作用实际

How to run single test method with phpunit?

I am struggling to run a single test method named testSaveAndDrop in the file escalation/EscalationGroupTest.php with phpunit .

Best practices to test protected methods with PHPUnit

I found the discussion on Do you test private method informative. I have decided, that in some classes, I want to have protected methods, but test them. Some of these methods are static and short. Because most of the public methods make use of them, I will probably be able to safely remove the tests later. But for starting with a TDD approach and avoid debugging, I really want to test them.

使用PHPUnit测试受保护方法的最佳实践

我发现了关于你是否测试私有方法信息的讨论。 我已经决定,在一些课堂上,我想要有受保护的方法,但是要测试它们。 其中一些方法是静态的和简短的。 因为大多数公共方法都使用它们,所以我可能会稍后安全地移除测试。 但是从TDD方法开始并避免调试,我真的想要测试它们。 我想到了以下几点: 方法对象在答案中的建议似乎是矫枉过正的。 从公共方法开始,当代码覆盖率由更高级别的测试给出时,将它们保护起来并移除测

safest way to create sessions in php

I'm working on a website and want to create user login and session. What is the safest way to check if session exists or not (like cookie or session variable check), or any better idea then using sessions in php? session_id() returns the session id for the current session or the empty string ("") if there is no current session (no current session id exists). http://de.php.net/m

最安全的方式来创建会话在PHP中

我正在一个网站上工作,并希望创建用户登录和会话。 什么是最安全的方法来检查会话是否存在(如cookie或会话变量检查),或任何更好的想法,然后在PHP中使用会话? 如果没有当前会话(不存在当前会话ID), session_id()将返回当前会话的会话ID或空字符串(“”)。 http://de.php.net/manual/en/function.session-id.php 但是这只是告诉你一个会话是否处于活动状态。 大多数情况下,我只是调用session_start(); 在每个

Omnicompletion stops giving useful predictions

I am trying to set up omni completion for PHP in vim 7.3 with ctags 5.9~svn20110310 on Ubuntu 12.04.1 (LTS) but I am running into a very strange issue where completion provides radically different predictions for instances of the same class.

Omnicompletion停止提供有用的预测

我尝试在Ubuntu 12.04.1(LTS)上使用ctags 5.9〜svn20110310在vim 7.3中设置omni完成,但是我遇到了一个很奇怪的问题,即完成对同一类的实例提供了完全不同的预测。 我有以下两个文件: // Foo.php class Foo { public function do_stuff() { echo 'Working...'; } } // index.php require 'Foo.php'; $f = new Foo(); $f->[cursor position 1] $g = new Foo(); $g->[cursor positio
