我想用libXML2解析UTF8格式的XML。 我的代码是用C语言编写的,我使用的是libXML2 v2.9.3。
我的代码如下:
xmlTextReaderPtr reader;
xmlTextWriterPtr writer;
writer = xmlNewTextWriterFilename("test.xml", 0);
xmlTextWriterStartDocument(writer, NULL, "UTF-8", NULL);
xmlTextWriterStartElement(writer, BAD_CAST "node_with_é_character");
xmlTextWriterEndElement(writer);
xmlTextWriterEndDocument(writer);
xmlFreeTextWriter(writer);
reader = xmlReaderForFile("test.xml", "UTF-8", XML_PARSE_RECOVER);
int ret = 1;
while (ret == 1) {
const xmlChar *nameT = xmlTextReaderConstName(reader);
printf("\n ---> %s\n",nameT);
ret = xmlTextReaderRead(reader);
}
输出为:
---> (null)
---> node_with_é_character
问题是“ node_with_ é _character”跟踪,而不是“ node_with_ é _character”
我的命令提示符设置为 “ chcp 1252” 。
我不明白为什么liXML2无法存储/读取“é”字符。

正如在Windows下的注释中所指出的那样,所以我想您的源代码可能不是UTF-8编码的,因此C字符串“node_with_é_character”在可执行文件中不是UTF-8编码的。
我不知道libxml2接口,但是代码示例非常清楚,它期望输入参数为UTF-8。参见http://xmlsoft.org/examples/testWriter.c
/* Write a comment as child of EXAMPLE.
* Please observe, that the input to the xmlTextWriter functions
* HAS to be in UTF-8, even if the output XML is encoded
* in iso-8859-1 */
tmp = ConvertInput("This is a comment with special chars: <\xE4\xF6\xFC>",
MY_ENCODING);
将您的源文件另存为UTF-8,将帮助您解决问题。
