问题 I've been messing with using RapidXML on one of my projects. It was all going so well until I decided to use it for writing out xml. My code is more or less as follows: //attempt to open the file for writing std::ofstream file(fileName.c_str()); if (!file.is_open()) return false; //the file didn't open xml_document<> doc; //creates the contents of the document... //... //... //write the document out to the file file << doc; //if I remove this line it compiles...but I kinda need this line to

rapidxml: how to iterate through nodes? Leaves out last sibling

阅读更多关于 rapidxml: how to iterate through nodes? Leaves out last sibling

问题 Using rapidxml I'm wanting to loop through a set of nodes, and am using what I found to be the best way to do this (from trusty stackoverflow, the doc doesn't appear to have an example of iteration): while (curNode->next_sibling() !=NULL ) { string shiftLength = curNode->first_attribute("shiftLength")->value(); cout << "Shift Length " << "\t" << shiftLength << endl; curNode = curNode->next_sibling(); } Unfortunately, on my OSX 10.6 this is leaving out the last sibling node - I guess because

How to parse an XML file with RapidXml

阅读更多关于 How to parse an XML file with RapidXml

问题 I have to parse an XML file in C++. I was researching and found the RapidXml library for this. I have doubts about doc.parse<0>(xml) . Can xml be an .xml file or does it need to be a string or char * ? If I can only use string or char * then I guess I need to read the whole file and store it in a char array and pass the pointer of it to the function? Is there a way to directly use a file because I would need to change the XML file inside the code also. If that is not possible in RapidXml then

C++ RapidXML get sibling of the same type?

阅读更多关于 C++ RapidXML get sibling of the same type?

问题 So, in RapidXML, I'm trying to loop through my file to get the data from some tileset nodes: rapidxml::xml_node<> *root_node = doc.first_node("map"); for(rapidxml::xml_node<> *tileset = root_node->first_node("tileset"); tileset != 0; tileset = tileset->next_sibling("tileset")) { // Iteration stuff... You're probably saying, what's the problem? Well, in RapidXML, the next_sibling() function optionally matches the name: xml_node<Ch>* next_sibling(const Ch *name=0, std::size_t name_size=0, bool

Rapidxml and UTF8

问题 I am using RapidXML, but I need to write my strings as UTF8, in Rapidxml Manual was explained it supports UTF8 , please tell me how can I use it via C++ ISO ? 回答1: The default mode of operation for RapidXML is to handle UTF-8 input. You would have to disable this explicitly using parse_no_utf8 to get other behaviour. Parse flag instructing the parser to disable UTF-8 handling and assume plain 8 bit characters. By default, UTF-8 handling is enabled. 来源： https://stackoverflow.com/questions

How to read Unicode XML values with rapidxml

阅读更多关于 How to read Unicode XML values with rapidxml

问题 RapidXML is one of the available libraries for parsing XML in c++. For getting the values, we can use something like: node->first_node("xmlnode")->value() This command returns a char* data type. Is there any way to read the value as Unicode so I can assign it in a WCHAR or wstring variable? 回答1: From the manual RapidXml is character type agnostic, and can work both with narrow and wide characters. Current version does not fully support UTF-16 or UTF-32, so use of wide characters is somewhat

How to fix RapidXML String ownership concerns?

阅读更多关于 How to fix RapidXML String ownership concerns?

问题 RapidXML is a fast, lightweight C++ XML DOM Parser, but it has some quirks. The worst of these to my mind is this: 3.2 Ownership Of Strings. Nodes and attributes produced by RapidXml do not own their name and value strings. They merely hold the pointers to them. This means you have to be careful when setting these values manually, by using xml_base::name(const Ch *) or xml_base::value(const Ch *) functions. Care must be taken to ensure that lifetime of the string passed is at least as long as

RapidXML reading from file - what is wrong here?

阅读更多关于 RapidXML reading from file - what is wrong here?

问题 What's the difference between these two methods of reading an input file? 1) Using 'ifstream.get()' and 2) Using a vector<char> with ifstreambuf_iterator<char> (less understood by me!) (other than the obvious answer of having nifty vector methods to work with) The input file is XML, and as you see below, immediately parsed into a rapidxml document. (initialized elsewhere, see example main function.) First, let me show you two ways to write the 'load_config' function, one using ifstream.get()

Errors with returning datatypes other than char* from XML-file using C++

问题 It's my first time using XML and I am currently trying to return an integer (actually want to return a double but haven't got that far yet) from an XML-file using C++. I'm using RAPIDXML and the following implementation: All files are in the same directory.
