The processing instruction target matching "[xX][mM][lL]" is not allowed怎么办？

Question

myeclipse没用过
把<?xml version="1.0" encoding="UTF-8"?>和<xml-body></xml-body>去掉可以吗

Answer 1

<?xml version="1.0" encoding="UTF-8"?>
<xml-body><?xml version="1.0" encoding="ISO-8859-1"?>
对阿你写这句的用语是什么？怎么有两个编码的？
而且xml标签用<xml-。会不会不行啊？看提示好像是你用了xml本身的保留字之类的做标签吧？
呵呵。。不知道是不是这样

第一个是空格问题，还有就是有两个XML Prolog,还有就是没有按照DTD的严格要求，试下用下面的
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE web-app SYSTEM "http://java.sun.com/dtd/web-app_2_3.dtd">
<web-app>

Answer 4

空格的原因 <?xml version="1.0" encoding="UTF-8"?>前边有空格。复制粘贴时造成的。

Answer 5

<?xml version="1.0" encoding="UTF-8"?>
注意？前后不要有空格。并加上：
<!DOCTYPE web-app SYSTEM "http://java.sun.com/dtd/web-app_2_3.dtd">

Answer 6

是<?xml version="1.0" encoding="UTF-8"?>出现了空行或者空格

Answer 7

我也出现了上面那种情况，是在struts-config.xml里面。我那里面没有空格还报那样的错误，真是郁闷啊，请各位高手指点一下啊。谢谢了
