c xml 如何生成器

你需要安装libxml2库。在大多数Linux发行版中，你可以使用包管理器安装它，例如在Ubuntu上你可以使用以下命令：

```bash

sudo apt-get install libxml2-dev

```

```c

include

include

include

int main() {

xmlOutputBufferPtr outputBuffer;

xmlWriterPtr writer;

int ret;

// 创建XML writer

writer = xmlWriterNew();

// 设置输出到文件

outputBuffer = xmlOutputBufferNewFilename("output.xml");

xmlWriterSetOutputBuffer(writer, outputBuffer);

// 开始XML文档

xmlWriterStartDocument(writer, "1.0", "UTF-8");

// 写入根元素

xmlWriterStartElement(writer, "root");

// 写入子元素

xmlWriterStartElement(writer, "child");

xmlWriterWriteElement(writer, "name", "value");

xmlWriterEndElement(writer);

// 结束根元素

xmlWriterEndElement(writer);

// 结束XML文档

xmlWriterEndDocument(writer);

// 清理资源

xmlOutputBufferFree(outputBuffer);

xmlWriterFree(writer);

return 0;
