我有错误:

Error Parsing /WEB-INF/includes/VerDatosProyeccion.xhtml: Error Traced[line: 4302] The processing instruction target matching "[xX][mM][lL]" is not allowed.

我正在使用相同代码的代码:http://jsfiddle.net/qxLn3h86/ .我将代码剪切并粘贴到我的代码中。

我的代码是这样的:

        <table id="tbl1">


<tr>
    <td>Name</td>
    <td>Birthday</td>
    <td>Amount</td>
    <td>Rebate (10%)</td>
  </tr>
  <tr>
    <td>Smith</td>
    <td data-type="DateTime" data-style="Date" data-value="1980-03-23">Mar 23 1980</td>
    <td data-type="Number" data-style="Currency" data-value="1234.56">$ 1,234.56</td>
    <td data-formula="=RC[-1]/10" data-type="Number" data-style="Currency">$ 123.45</td>
  </tr>
  <tr>
    <td>Doe</td>
    <td data-type="DateTime" data-style="Date" data-value="1978-11-05">Nov 05 1978</td>
    <td data-type="Number" data-style="Currency" data-value="2345.67">$ 2,345.67</td>
    <td data-formula="=RC[-1]/10" data-type="Number" data-style="Currency">$ 234.56</td>
  </tr>
</table>

<table id="tbl2">
  <tr>
    <td>Product</td>
    <td>Price</td>
    <td>Available</td>
    <td>Count</td>
  </tr>
  <tr>
    <td>Bred</td>
    <td data-type="Number" data-style="Currency" data-value="1.89">$ 1.89</td>
    <td data-type="Boolean" data-value="1">yes</td>
    <td data-type="Number" data-value="123">123</td>
  </tr>
  <tr>
    <td>Butter</td>
    <td data-type="Number" data-style="Currency" data-value=".89">$ .89</td>
    <td data-type="Boolean" data-value="0">no</td>
    <td data-type="Number" data-value="0">0</td>
  </tr>
</table>

最佳答案

一般答案

当 XML 声明 ( <?xml version="1.0" ?> ) 出现在 XML 文档的最顶部以外的任何地方时，解析器通常会将它们与处理指令混淆并发出误导性的错误消息。

修复错误的规范答案，

Error Traced[line: 4302] The processing instruction target matching "[xX][mM][lL]" is not allowed.

本问答涵盖了与 XML 声明相关的所有类似错误:

• Error: The processing instruction target matching "[xX][mM][lL]" is not allowed

您将在此处找到针对此类错误的三个原因的解决方案:

1. XML声明前的可见内容
2. XML声明前的不可见内容
3. 重复的 XML 声明

针对您的具体情况的建议

尝试将您的代码包装在 script 中与 CDATA :

<script>
//<![CDATA[
    ...code containing XML declaration (`<?xml version="1.0"?>`)
//]]>
</script>

这样 XML 声明就不会被解释为封闭文档的一部分。 XML 声明只能出现在 XML 文档的最顶部(并且最多只能有一个)。

如果这不能解决您的问题，请检查您输出 XML 声明的位置。确保 XML 声明之前没有可见或不可见的内容，并确保输出中没有多个 XML 声明。有关详细信息，请参阅:

• Error: The processing instruction target matching "[xX][mM][lL]" is not allowed
• Are multiple XML declarations in a document well-formed XML?
