的XQuery：令牌化文本，同時保留標籤

Question

考慮以下XQuery代碼：

let $foo := <root>This is a <tag>test</tag>. This is <tag>only</tag> a <tag>test</tag>.</root> 
for $s in tokenize($foo, "\. ") 
return <sentence>{$s}</sentence> 

它返回$foo分割（很天真）成句子—但它也剔除包含在$foo標籤：

<sentence>this is a test.</sentence> 
<sentence>this is only a test.</sentence> 

假設我想分割$foo爲句子，而保留嵌入式標籤，給出的輸出如下所示：

<sentence>this is a <tag>test</tag>.</sentence> 
<sentence>this is <tag>only</tag> a <tag>test</tag>.</sentence> 

我應該如何處理這個問題？

Answer 1

我希望這是你在尋找：

let $foo := <root>This is a <tag>test</tag>. This is <tag>only</tag> a <tag>test</tag>.</root> 
for $s in tokenize(xdmp:quote($foo/node()), "\. ") 
return xdmp:unquote("<sentence>"||$s||"</sentence>")
