XML - XSLT转换 - 生成特殊的"<？...？>"标记

Question

我正在转换一些XML数据以适应格式为"Excel XML Spreadsheet 2003"的文档

一切正常,但我在生成结果文件的正确标题时遇到问题.它应该基本上是以下形式:

<?xml version="1.0"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:o="urn:schemas-microsoft-com:office:office"
 xmlns:x="urn:schemas-microsoft-com:office:excel"
 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:html="http://www.w3.org/TR/REC-html40">

 <!-- end of header here and the transformation data goes below -->

<Workbook>

XSLT文件是

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes" media-type="text/xml"/>
    <xsl:template match="/">
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:o="urn:schemas-microsoft-com:office:office"
 xmlns:x="urn:schemas-microsoft-com:office:excel"
 xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
 xmlns:html="http://www.w3.org/TR/REC-html40">

但是在结果文件<?mso-application progid="Excel.Sheet"?>中缺少该行.

我知道这<? ...?>是一个特殊的标签 - 所以可能会质疑XSLT是如何产生的

谢谢

有了任何输入,这个样式表:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:output method="xml" version="1.0" encoding="utf-8" indent="yes" media-type="text/xml"/>
    <xsl:template match="/">
        <xsl:processing-instruction name="mso-application">progid="Excel.Sheet"</xsl:processing-instruction>
        <Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet"
                  xmlns:o="urn:schemas-microsoft-com:office:office"
                  xmlns:x="urn:schemas-microsoft-com:office:excel"
                  xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet"
                  xmlns:html="http://www.w3.org/TR/REC-html40"/>
    </xsl:template>
</xsl:stylesheet>

结果:

<?xml version="1.0" encoding="utf-8"?>
<?mso-application progid="Excel.Sheet"?>
<Workbook xmlns="urn:schemas-microsoft-com:office:spreadsheet" xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns:ss="urn:schemas-microsoft-com:office:spreadsheet" xmlns:html="http://www.w3.org/TR/REC-html40" />
