没有为文档检测到语法约束（DTD或XML模式） [英] No grammar constraints (DTD or XML schema) detected for the document

问题描述

我有这个dtd： http://fast-code.sourceforge.net/template.dtd
但是当我包含一个xml我收到警告：
没有为文档检测到语法约束（DTD或XML模式）。
xml是：

 <？xml version =1.0encoding =UTF-8？> ; 
<！DOCTYPE templates PUBLIC// UNKNOWN /http://fast-code.sourceforge.net/template.dtd\"> 
 
< templates> 
< template type =INSTANCE_OF_CLASS> 
< description>用于创建类< / description>的实例
< variation> asasa< / variation> 
< variation-field> asasa< / variation-field> 
< class-pattern> asasa< / class-pattern> 
< getter-setter> setter< / getter-setter> 
< allowed-file-extensions> java< / allowed-file-extensions> 
< number-required-classes> 1< / number-required-classes> 
< allow-multiple-variation> false< / allow-multiple-variation> 
< template-body> 
<！[CDATA [
 //创建$ {class_name}的新实例
 final $ {class_name} $ {instance} = new $ {class_name}（）; 
 #foreach（$ field in $ {fields}）
 $ {instance}。$ {field.setter}（$ {field.value}）; 
 #end 
]]> 
< / template-body> 
< / template> 
< / templates> 
  

编辑：我更改了xml，我现在得到这个错误：

元素类型模板的内容必须匹配（description，variation？，variation-field？，allow-
多变量？，类模式？，getter-setter？，allowed-file-extensions？，number-required-
classes？，template-body）。

解决方案

在我的情况下，我已经解决了这个烦人的警告，只需添加<！DOCTYPE xml> <？xml ...> 标签。

 <？xml version =1.0encoding =UTF-8？> 
<！DOCTYPE xml> 
  

I have this dtd : http://fast-code.sourceforge.net/template.dtd But when I include in an xml I get the warning : No grammar constraints (DTD or XML schema) detected for the document. The xml is :

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE templates PUBLIC "//UNKNOWN/" "http://fast-code.sourceforge.net/template.dtd">

<templates>
<template type="INSTANCE_OF_CLASS">
    <description>Used to Create instance of class</description>
    <variation>asasa</variation>
    <variation-field>asasa</variation-field>
    <class-pattern>asasa</class-pattern>
    <getter-setter>setter</getter-setter>
    <allowed-file-extensions>java</allowed-file-extensions>
    <number-required-classes>1</number-required-classes>
    <allow-multiple-variation>false</allow-multiple-variation>
    <template-body>
        <![CDATA[
            // Creating new instance of ${class_name}
            final ${class_name} ${instance} = new ${class_name}();
            #foreach ($field in ${fields})
                ${instance}.${field.setter}(${field.value});
            #end
        ]]>
    </template-body>
</template>
</templates>

EDIT : I changed the xml, I am getting this error now:

The content of element type "template" must match "(description,variation?,variation-field?,allow- multiple-variation?,class-pattern?,getter-setter?,allowed-file-extensions?,number-required- classes?,template-body)".

解决方案

In my case I have solved this annoying warning by simply adding the <!DOCTYPE xml> after the <?xml ... > tag.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xml>
