Convert a string to XML input stream in java

Question

Hi,

I'm trying to generate a PDF document using FOP and Java.

I receive the XML as a string and not as a file.

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.

Please provide your suggestions.

Answer 1

Use ByteArrayInputStream:

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

Answer 2

You probably want to convert it to a Reader, not an InputStream. Use StringReader to do this. StreamSource has a constructor that takes a Reader, and you can pass that StreamSource to Transformer.transform().

I say you probably want a Reader rather than an InputStream because a String holds characters, not bytes, and an InputStream is a stream of bytes while a Reader is a stream of characters.

Answer 3

new StreamSource(new StringReader(str))
