Convert a string to XML input stream in java
提问by jobinbasani
I'm trying to generate a PDF document using FOP and Java.
我正在尝试使用 FOP 和 Java 生成 PDF 文档。
I receive the XML as a string and not as a file.
我将 XML 作为字符串而不是文件接收。
How can I convert this XML string to an XML input stream so that I can call xslfoTransformer.transform(source, res); where source is my XML string as an Input stream.
如何将此 XML 字符串转换为 XML 输入流，以便我可以调用 xslfoTransformer.transform(source, res); 其中 source 是我的 XML 字符串作为输入流。
Please provide your suggestions.
请提供您的建议。

You probably want to convert it to a Reader, not an InputStream. Use StringReaderto do this. StreamSource has a constructor that takes a Reader, and you can pass that StreamSourceto Transformer.transform().
您可能想将其转换为 aReader而不是InputStream。使用StringReader来做到这一点。StreamSource 有一个接受 Reader 的构造函数，您可以将它传递StreamSource给 Transformer.transform()。
I say you probably want a Readerrather than an InputStreambecause a String holds characters, not bytes, and an InputStreamis a stream of bytes while a Readeris a stream of characters.
我说你可能想要 aReader而不是 anInputStream因为 String 保存字符，而不是字节，并且 anInputStream是字节流而 aReader是字符流。

Use ByteArrayInputStream:
String S = ...;
InputStream source = new ByteArrayInputStream(S.getBytes(encoding))

new StreamSource(new StringReader(str))
