嘿，我是使用eXist和Xquery的新手。
这是我的问题。我尝试使用xQuery从xml文件（存储在eXist数据库中）中检索一些数据。当我只是在没有任何条件的情况下进行检索时它会变好。 当我使用某些条件时，它会给我这个错误：
XML解析错误：文档元素之后的垃圾
这是xml文件：

这是我的xql代码：
declare namespace xdb = "http://exist-db.org/xquery/xmldb";
for $x in doc("/db/skripsi/database/PTI/spreadrum_g189.xml")//*
where data($x)="1"
return $x
xql代码实际上在沙盒中工作得很好，但我不知道为什么它在实际实现时会给我错误：（。
答案 0 :(得分：0)
我不知道如何重现您报告的问题，但如果您只在文档的文本节点上应用相等性测试，那么您的查询会更准确：
declare namespace xdb = "http://exist-db.org/xquery/xmldb";
for $x in doc("/db/skripsi/database/PTI/spreadrum_g189.xml")//*
where $x/text() = "1"
return $x
否则，data()函数将在文档的所有元素节点上执行（即使是那些具有更多后代节点的节点），这可能需要很长时间，如果处理过的数据也会导致错误大。
希望这有帮助， 基督教

XML Parsing Error: junk after document element
这指向关闭文档节点之后的一些垃圾内容 - 在这种情况下是</produk>之后。 XML不允许文档节点之后的任何内容（expcept PIs, comments, whitespace）。在某些文本编辑器中打开内容，确保没有不需要的字符作为受保护的空白，BOM等。
我从您粘贴的文件中复制了整个XML内容，也很好。也许试着把它复制回来。
