使用XQuery进行XML到CSV的转换

for $b in /*/book
    return
      concat(escape-html-uri(string-join(($b/@isbn,$b/title,$b/description
                                          )
                                           /normalize-space(),",")
                             ),codepoints-to-string(10))

基于XSLT 2的验证：

<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:sequence select=
   "for $b in /*/book
       return
         concat(escape-html-uri(string-join(($b/@isbn,$b/description
                                             )
                                              /normalize-space(),',')
                                ),codepoints-to-string(10))"/>
 </xsl:template>
</xsl:stylesheet>

当对提供的XML文档应用此转换时(根据其格式不正确)：

<books>
    <book isbn="1590593049">
        <title>Extending Flash MX 2004</title>
        <description>

        </description>

产生了想要的正确结果：

更新：

在评论中,OP已经请求任何文本逗号被引号包围,并且(之后)任何引号被两个引号替换,并且最后,如果wholw结果包含引号,则它必须被(包围)(单引号.

这是一个纯XPath 2.0表达式,它产生了这个：

for $b in /*/book,$q in codepoints-to-string(34),$NL in codepoints-to-string(10),$isbn in normalize-space(replace($b/@isbn,concat($q,$q))),$t in normalize-space(replace($b/title,$d in normalize-space(replace($b/description,$res in
     escape-html-uri(string-join(($isbn,$t,$d),')),$res2 in replace($res,$q,$q))
   return
    if(contains($res2,$q))
       then concat($q,$res2,$NL)
       else concat($res2,$NL)

当针对此(使用新的测试用例扩展)XML文档评估此XPath表达式时：
