tinyXml如何添加一个元素 [英] tinyXml how to add an element

问题描述

我有以下：

TiXmlDocument doc;
TiXmlDeclaration * decl = new TiXmlDeclaration( "1.0", "utf-8", "");
doc.LinkEndChild( decl );
TiXmlElement * root = new TiXmlElement( "Value" );  
TiXmlElement * element = new TiXmlElement( "number" );  
root->LinkEndChild( element);  

TiXmlText * text = new TiXmlText( "5" );  
element->LinkEndChild( text ); 

这样吗？我想要有.xml像：

IT IS OK LIKE THIS? I WOULD LIKE TO HAVE the .xml like:

<Value>
<number>5</number>
</Value>

THX！

我可以有一个int值作为字符串。如果它;确定如果我以那种方式发送xml文件？或者有一种方法来指定5是一个int而不是一个文本？

my question is if i can have a int value as a string. if it;s ok if i send in that way the xml file? or is there a way to specify that 5 is an int and not a text?

推荐答案

如果要附加包含整数值的节点，此整数首先转换为字符串。您可以使用各种功能，但我更喜欢 snprintf （其他人可能不同:)）

If you want to append a node containing an integer value, this integer has first be transformed to a string. You can do this with a variety of functions, but I prefer snprintf (others might differ :) )

以下示例：

int five = 5;
char buf[256];
snprintf(buf, sizeof(buf), "%d", five); // transforms the integer to a string
TiXmlText * text = new TiXmlText( buf );  
element->LinkEndChild( text );
