XML XSLT结果文档fseek [英] XML XSLT Result-Document fseek
问题描述
使用XSLT转换，我想将一个XML文件转换成一个HTML文件，该XML文件又代表另一个文件的各个块，并带有指向所代表文件的链接.
Using XSLT transformation I want to convert an XML file, that in turn represents various chunks of another file, into a HTML file with a link to the file that was represented.
输入XML文件:
<File>
<Name>foo.jpg<Name>
<Chunk>
<Offset>200</Offset>
<Length>100</Length>
<Data>
<![CDATA[data bytes, encoded in base64, can be greater than length 100 too, but first 100 decoded bytes are valid.]]>
</Data>
</Chunk>
<Chunk>
...
</File>
输出应为html文件，该文件具有指向foo.jpg的有效链接，即，存在另一个名为"foo.jpg"的隐式输出文件，其中包含块中cdata节中的数据，且其指定偏移量./p>
The output should be a html file that has a valid link to foo.jpg, i.e., there is another implicit output file called "foo.jpg" with data from the cdata sections in the chunks, at their specified offsets.
<html>
<body>
<a href="http://example.com/images/foo.jpg">file</a>
</body>
</html>
推荐答案
此XSLT 2.0转换:
<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:template match="/*">
<xsl:document>
<html>
<body>
<a href="http://example.com/images/{Name}">file</a>
</body>
</html>
</xsl:document>
<xsl:result-document href="file:///c:/temp/delete/{Name}" method="text">
<xsl:apply-templates select="Chunk">
<xsl:sort select="Offset" data-type="number"/>
</xsl:apply-templates>
</xsl:result-document>
</xsl:template>
<xsl:template match="Chunk">
<xsl:value-of select="substring(Data, 1, Length)"/>
</xsl:template>
</xsl:stylesheet>
应用于此XML文档(具有两个块):
<File>
<Name>foo.jpg</Name>
<Chunk>
<Offset>200</Offset>
<Length>100</Length>
<Data>A01234567891234567890234567890134567890124567890123567890123467890123457890123456890123456790123456780123456789</Data>
</Chunk>
<Chunk>
<Offset>1</Offset>
<Length>200</Length>
<Data>Z0123456789123456789023456789013456789012456789012356789012346789012345789012345689012345679012345678012345678901234567891234567890234567890134567890124567890123567890123467890123457890123456890123456790123456780123456789</Data>
</Chunk>
</File>
产生想要的正确结果:
<html>
<body><a href="http://example.com/images/foo.jpg">file</a></body>
</html>
和创建的文件:c:\temp\delete\foo.jpg具有正确的所需内容:
and the created file: c:\temp\delete\foo.jpg has the correct, wanted contents:
Z0123456789123456789023456789013456789012456789012356789012346789012345789012345689012345679012345678012345678901234567891234567890234567890134567890124567890123567890123467890123457890123456890123456A012345678912345678902345678901345678901245678901235678901234678901234578901234568901234567901234567
