Xslt 带空格的XSL读取处理指令

在源xml文档中，我有一条包含空格的处理指令-

如何使用xslt读取和处理此处理指令

如果我尝试使用处理指令（“tagtodelete”），我会得到一个错误-任何处理指令都不会被命名为“tagtodelete”。无效的QName{要删除的标记}

请提供帮助。

选择此处理指令后，您不完全清楚要对其执行什么操作，但处理指令的名称是

中的一部分。选择此处理指令后，您不完全清楚要对其执行什么操作，但是，如果处理指令的字符串值中可能存在数量不确定的空格字符，则处理指令的名称是
中的部分，如：

<?Tag To Delete?>

<?Tag   To    Delete    ?>

<?Tag To            Delete ?>

<?Tag To Delete?><?Tag To    Delete    ?><?Tag To            Delete ?>

这里是一个简短的、基于XSLT的验证：

processing-instruction('Tag')[normalize-space() = 'To Delete']

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
  <xsl:copy-of select=
  "/*/processing-instruction('Tag')[normalize-space() = 'To Delete']"/>
 </xsl:template>
</xsl:stylesheet>

<t>
    <?Tag To Delete?>
    <?Tag   Not To    Delete    ?>
    <?Tag   To    Delete    ?>
    <?Tag To            Delete ?>
</t>



当此转换应用于以下XML文档时：

processing-instruction('Tag')[normalize-space() = 'To Delete']

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
 <xsl:output omit-xml-declaration="yes" indent="yes"/>

 <xsl:template match="/">
  <xsl:copy-of select=
  "/*/processing-instruction('Tag')[normalize-space() = 'To Delete']"/>
 </xsl:template>
</xsl:stylesheet>

<t>
    <?Tag To Delete?>
    <?Tag   Not To    Delete    ?>
    <?Tag   To    Delete    ?>
    <?Tag To            Delete ?>
</t>



计算XPath表达式，并将计算结果（选定节点）复制到输出中：

<?Tag To Delete?>

<?Tag   To    Delete    ?>

<?Tag To            Delete ?>

<?Tag To Delete?><?Tag To    Delete    ?><?Tag To            Delete ?>

以防处理指令的字符串值中可能存在数量不确定的空格字符，如：

<?Tag To Delete?>

<?Tag   To    Delete    ?>

<?Tag To            Delete ?>

<?Tag To Delete?><?Tag To    Delete    ?><?Tag To            Delete ?>

processing-instruction('Tag')[normalize-space() = 'To Delete']

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

 <xsl:template match="/">
  <xsl:copy-of select=
  "/*/processing-instruction('Tag')[normalize-space() = 'To Delete']"/>
 </xsl:template>
</xsl:stylesheet>

<t>
    <?Tag To Delete?>
    <?Tag   Not To    Delete    ?>
    <?Tag   To    Delete    ?>
    <?Tag To            Delete ?>
</t>
