Question

我很想知道,能否将变数的内容(可能包含有幻觉的html)列入一个数据部分。

I am using XQuery with eXist and I just can t seem to get it working.

I tried

<![CDATA[ $data ]]>
<![CDATA[ {$data} ]]>

在这两种情况下,变量不以内容取代,而是分别保持数据和{数据}。

I also tried using concat and other string functions, but these resulted in <![CDATA[ becoming <![CDATA[.

元数据包括:从一位htmlwysiwyg编辑获取/张贴数据。

xquery version "1.0";
declare namespace request="http://exist-db.org/xquery/request";

let $data := request:get-parameter("content" , "")
return <![CDATA[ {$data} ]]>

Does anyone now how it should be done? Thanks in advance.

Answer 1

@Alejandro是正确的。 See Priscilla Walmsley s XQuery book pp. 280-281。 “《空运公约》一节中的所有案文都字面上了;不可能在《空运公约》条款中列入所附表述。

If you want to deal with "messy HTML" by fixing malformed bits, you may wish to check out the NekoHTML-powered util:parse-html() function. Pass the messy HTML string, and you ll get well-formed XML node on the other end.

Answer 2

如果你想将一些信息化但具有任意性的超文本编码为示意图,例如将使用:

eg.

xquery version "1.0";
declare namespace util="http://exist-db.org/xquery/util";

let $data := <div><h1>stuff</h1><a href="url"> <img src="image"/></a></div>
return
   util:serialize($data,"method=xml"))

The effect is the same as if the XML were enclosed in CDATA, with the reserved XML characters encoded.
