我想在更改某些属性值后保持原始xml格式。除更改属性外，如何维护格式？
我在java8，apache9和日食氧气上工作。

我使用这样的代码。
<a>
<b id="123"
name="456"
value="789">
<c id="awe"
name="try">
</a>
此代码后，XMl将被重写，并更改格式。
Document doc = getConfigDocument();
NodeList nl = doc.getElementsByTagName("serverInfo");
Element oasisElement = (Element) doc.getElementsByTagName("b").item(0);
oasisElement.setAttribute("id", "1231");
Transformer tr;
try
{
tr = TransformerFactory.newInstance().newTransformer();
tr.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tr.setOutputProperty(OutputKeys.INDENT, "yes");
tr.transform(new DOMSource(doc), new StreamResult(new File(getConfigRoot())));
resultMsg = "success";
}
我可以保持xml格式，但不能更改如下所示的目标，还是保持原始格式？
<a>
<b id="1231" name="456" value="789">
<c id="awe" name="try">
</a>
答案 0 :(得分：1)
否，XML解析器不会向应用程序报告详细的布局，因此该应用程序（在本例中为XSLT处理器）无法保留原始布局。
但是，如果输入格式遵循系统规则，则可以使序列化程序（处理XSLT转换的结果）遵循相同的规则。如果您使用Saxon序列化程序而不是内置的JDK（Xalan）序列化程序，则可以通过指定序列化属性来获得与输入格式非常接近的内容：
indent=yes
saxon:indent-spaces=1
saxon:line-length=10
saxon:attribute-order="id name value"
为此，您需要Saxon-PE或更高版本。
