XQuery：如何输出字符串文字和属性值

Question

test.xqy:

element test
{
  attribute haha {"&"}
}

command line:

$ basex test.xqy
<test haha="&amp;"/>

And I need the output to be: <test haha="&"/> . The XML entity is not processed by BaseX?

Answer 1

The document <test haha="&"/> is not well-formed, so there's no chance to get this output with BaseX or any other XML processor. However, the value of haha is indeed '&'; you will see this if you return the attribute value as string:

string(<test haha="&amp;"/>/@haha)
