从节点到字符串的 Scala XML 警告

Question

我的问题是关于scala.xml 以及从Node 类型到String 的转换（使用任何buildString 或toString 方法）。

当我将这种转换为标准输出时，我会收到有关输入的警告列表，如下所示：

line 2 column 2 - Warning: unknown attribute "myAttribute1"
line 3 column 9 - Warning: unknown attribute "myAttribute2"
line 6 column 9 - Warning: unknown attribute "myAttribute3"
line 7 column 13 - Warning: unknown attribute "myAttribute4"
line 7 column 13 - Warning: unknown attribute "myAttribute5"
line 13 column 25 - Warning: <th> attribute "width" has invalid value "3%"
line 15 column 36 - Warning: <th> attribute "width" has invalid value "5%"
line 17 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 19 column 36 - Warning: <th> attribute "width" has invalid value "15%"
line 21 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 23 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 25 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 27 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 29 column 36 - Warning: <th> attribute "width" has invalid value "3%"
line 35 column 22 - Warning: unknown attribute "data-col-count"
line 41 column 15 - Warning: inserting missing 'title' element

The table summary attribute should be used to describe
the table structure. It is very helpful for people using
non-visual browsers. The scope and headers attributes for
table cells are useful for specifying which headers apply
to each table cell, enabling non-visual browsers to provide
a meaningful context for each cell.

所以，我的问题是是否有办法摆脱这种输出。 生成这个的代码只是：

data.buildString(true).getBytes(StandardCharsets.UTF_8)

其中数据是Scala.xml.Node 谢谢

编辑

我尝试从 Node 解析到 String 并返回到 REPL，但我没有收到任何警告。

为了解析，我使用了一个自定义对象，它从 scala.xml 扩展了 XMLLooader，并带有 SAXParser 和 setValidation(false)。然后我就使用loadString(input) 来获取我的节点。

查看SAXParser 的文档，我在这里结束：https://docs.oracle.com/javase/7/docs/api/org/xml/sax/helpers/DefaultHandler.html#warning(org.xml.sax.SAXParseException) 上面写着，在默认情况下没有为警告提供任何操作。

看起来您的输出来自 this question about removing warnings 中所述的 JTidy，或者可能来自其他一些“整洁”的库。

当我尝试你的线路时：

data.buildString(true).getBytes(StandardCharsets.UTF_8)

它没有给我任何你得到的输出，也许是程序的另一部分导致了这个？
