libxml2 - 如何从 xml 文件中删除 xml 版本？

Question

enter code here

代码部分

      xmlTextWriterPtr XMLWriter = xmlNewTextWriterFilename("example.xml",0);
      xmlTextWriterStartDocument(XMLWriter, NULL, NULL, NULL);

      xmlTextWriterStartElement(XMLWriter,BAD_CAST "Powersettings");
      xmlTextWriterSetIndent(XMLWriter,1);
      xmlTextWriterWriteElement(XMLWriter,BAD_CAST "PowerScheme",BAD_CAST "Testing");
      xmlTextWriterEndElement(XMLWriter);
      xmlTextWriterEndElement(XMLWriter);

      xmlTextWriterEndDocument(XMLWriter);
      xmlFreeTextWriter(XMLWriter);
      xmlCleanupCharEncodingHandlers();
      xmlCleanupParser();

这是我创建 xml 的代码，libxml2 是这里使用的库。

xml contents,
<?xml version="1.0"?>
<Powersettings>
 <PowerScheme>Testing</PowerScheme>
</Powersettings>

你能帮我从我的xml中删除“”部分吗？

只需省略对xmlTextWriterStartDocument. 请注意，您仍然必须调用xmlTextWriterEndDocument。
