#xd；第13名；在读写XML文件时

Question

Today is a fine day.

So does everyday.

并且在写入之后，输出

Today is a fine day.

So does everyday.

实际预期和所需产出

<someNode>Today is a fine day.

So does everyday.
</someNode>

节点文本值中的新行是有意的，需要保持原样。

// Get Input XML stream from API
URL apiURL = new URL(API_Url);
HttpsURLConnection httpsAPIURLConn;
httpsAPIURLConn = (HttpsURLConnection) apiURL.openConnection();
httpsAPIURLConn.setConnectTimeout(10000); // timeout
httpsAPIURLConn.setDoInput(true);
InputStream inStream = httpsAPIURLConn.getInputStream();

// Data stream okay, Start StaX XLIFF reader
XMLInputFactory xmlInputFactory = XMLInputFactory.newInstance();
// This is to read entity referenced strings
xmlInputFactory.setProperty(XMLInputFactory.IS_COALESCING, true);

// StaX StreamReader
XMLStreamReader xmlStreamReader = xmlInputFactory.createXMLStreamReader(new BufferedInputStream(inStream), "UTF-8");

// Read and load XML data to in-memory database to filter and process

// After processing and writing new Element structure to org.w3c.dom.Document
// write the content into xml file
TransformerFactory transformerFactory = TransformerFactory.newInstance();
Transformer tr = transformerFactory.newTransformer();
tr.setOutputProperty(OutputKeys.INDENT, "yes");
tr.setOutputProperty("{http://xml.apache.org/xslt}indent-amount", "2");
tr.setOutputProperty(OutputKeys.METHOD, "xml");
tr.setOutputProperty(OutputKeys.ENCODING, "UTF-8");
tr.setOutputProperty(OutputKeys.STANDALONE, "no");

DOMSource source = new DOMSource(doc);
File file = new File(xmlFilePath);
Writer outputStream = new OutputStreamWriter(new FileOutputStream(file), "UTF-8");
StreamResult result = new StreamResult(outputStream);
tr.transform(source, result);

不确定我到底错过了什么。但任何建议或帮助都会很好。

最简单的解决方案（除了连接到SAX事件流之外）是编写一个XSLT脚本，它可以执行您所需要的功能，并将其作为您的转换器而不是默认的标识转换器来调用。

有关建议，请参见http://en.wikipedia.org/wiki/identity_transform#using_xslt。

然后，您需要提供自己的转换文本节点的规则，通过将ASCII13字符转换为空字符串来删除这些字符。详情见https://stackoverflow.com/a/5084382/53897。
