这个错误,
不允许处理指令目标匹配“[xX][mM][lL]”
每当我运行以如下开头的XSLT页面时，都会发生这种情况:
<?xml version="1.0" encoding="windows-1256"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:include href="../header.xsl"/>
<xsl:template match="/">
<xsl:call-template name="pstyle"/>
<xsl:call-template name="Validation"/>
<xsl:variable name="strLang">
<xsl:value-of select="//lang"/>
</xsl:variable>
<!-- ////////////// Page Title ///////////// -->
<title>
<xsl:value-of select="//ListStudentFinishedExam.Title"/>
</title>
注意:我删除了第一行之前的任何前导空格，但错误仍然发生!
基于xerces的工具将发出以下错误
The processing instruction target matching "[xX][mM][lL]" is not allowed.
当在XML文件顶部以外的任何地方遇到XML声明时。
这是一条有效的诊断消息;在这种情况下，其他XML解析器应该发出类似的错误消息。
要纠正该问题，请检查以下可能性:
Some blank space or other visible content exists before the <?xml ?>
declaration.
Resolution: remove blank space or any other
visible content before the XML declaration.
Some invisible content exists before the <?xml ?>
declaration. Most commonly this is a Byte Order Mark
(BOM).
Resolution:
Remove the BOM using techniques such as those suggested by the W3C
page on the BOM in HTML.
A stray <?xml ?> declaration exists within the XML content.
This can happen when XML files are combined programmatically or
via cut-and-paste. There can only be one <?xml ?> declaration
in an XML file, and it can only be at the top.
Resolution: Search for
<?xml in a case-insensitive manner, and remove all but the top XML
declaration from the file.
