本文介绍了用于XML字符串的XML阅读器，而不是读取文件的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用了下面的代码，它仅读取XML文件中存在的xml数据.但是我无法通过给出以下内容(XML字符串)来运行:
< note date ="07/22/2011"< to> John Doe</to< Dave Smith</from< body"仍然吃午饭吗?< body> /note>
i have used belowpiece of code it is reading only xml data present inside XML files.but i am unable to run by giving like the following(XML String):
<note date="07/22/2011"><to>John Doe</to><from>Dave Smith</from><body>Still up for lunch?</body></note>
#include <stdio.h>
#include <libxml/xmlreader.h>
int main(int argc, char **argv)
{
if(argc != 2)
return (0);
const char *fileName = argv[1];
xmlTextReaderPtr reader;
reader = xmlReaderForFile(fileName, NULL, 0);
const char *temp;
int i;
while(xmlTextReaderRead(reader)) {
switch(xmlTextReaderNodeType(reader)) {
case XML_READER_TYPE_ELEMENT:
for(i = 0 ; i < xmlTextReaderDepth(reader) ; i++)
printf("\t");
temp = (char *)xmlTextReaderConstName(reader);
printf("Element: %s", temp);
while(xmlTextReaderMoveToNextAttribute(reader)) {
temp = (char *)xmlTextReaderConstName(reader);
printf(" %s", temp);
temp = (char *)xmlTextReaderConstValue(reader);
printf("=\"%s\"", temp);
}
xmlTextReaderMoveToElement(reader);
printf("\n");
continue;
case XML_READER_TYPE_TEXT:
temp = (char *)xmlTextReaderConstValue(reader);
for(i = 0 ; i < xmlTextReaderDepth(reader) ; i++)
printf("\t");
printf("\t%s", temp);
printf("\n");
continue;
}
}
xmlFreeTextReader(reader);
xmlCleanupParser();
return 0;
}
推荐答案
当然不是！
它毕竟会说xmlReaderForFile，不是吗?
您为什么不只使用 xmlReaderForMemory [
Well of course not!
It does say xmlReaderForFile after all, doesn''t it?
Why aren''t you just using xmlReaderForMemory[^]
