如何使用XSLT 1.0提取嵌入（FileMaker）XML中的SVG文件作为十六进制代码
我有一个XML文件（FileMaker fm14布局fmxmlsnippet），其中包含HexData标记中的SVG文件，如下所示：
<HexData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exData>
（周围XML的其余部分并不重要）
我需要从HexData中解码SVG文件
在其他语言中，这可以通过一个循环解决：
- 将每对十六进制数字转换为字符...
- ...当你去的时候把它连成一个字符串
- 将字符串输出为XML文件
- 在XSLT 1.0中是否可以实现实体到字符的转换（浏览器自然执行）？
- 或直接进行十六进制转换？
- 是否更容易将xls：output设置为text而不是xml？
循环很容易在XSLT 1.0中实现，作为递归命名模板，读取每两个十六进制数字 - 但它结束：XSLT 1.0缺少char（）函数！
我的第一个字符转换解决方案 - 简单地将十六进制字符转换为十六进制实体 - 有点半成功......
以下命名模板：
<xsl:template name="HexData.toString">
<xsl:param name="HexData"/>
<!-- -->
<xsl:if test="string-length($HexData)>1">
<!-- Output char as hex entity -->
<xsl:value-of select="'&#x'" disable-output-escaping="yes"/>
<xsl:value-of select="translate(substring($HexData,1,2),'abcdef','ABCDEF')"/>
<xsl:value-of select="';'"/>
<!-- recurse -->
<xsl:call-template name="HexData.toString">
<xsl:with-param name="HexData" select="substring($HexData,3)"/>
</xsl:call-template>
</xsl:if>
</xsl:template>
... 几乎会产生正确的结果：

如果您复制那个字符串并再次在浏览器中查看它，您将获得我想要提取的SVG图像：
