La cible de l'instruction de traitement correspondant à "[xX] [mM] [lL]" n'est pas autorisée. Erreur XML

Question

J'ai l'erreur:

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

J'utilise le code de même code de: http://jsfiddle.net/qxLn3h86/. J'ai coupé le code et le passé dans mon code.

Mon code ressemble à ceci:

 <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>

Essayer enroulant votre code dans script avec CDATA:

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

de telle sorte que la déclaration XML n'est pas interprétée comme partie du document englobante. Les déclarations XML ne peuvent apparaître qu'en haut d'un document XML (et il ne peut y en avoir qu'une au maximum).

Si cela ne résout pas votre problème, examinez l'emplacement de sortie de la déclaration XML. Assurez-vous qu'il n'y a pas de contenu visible ou invisible avant la déclaration XML et assurez-vous qu'il n'y a pas plusieurs déclarations XML dans la sortie. Pour plus de détails, voir:

• Are multiple XML declarations in a document well-formed XML?
