public StandardUnparsedTextResolver()

Method Detail

setDebugging

public void setDebugging(boolean debug)

Set debugging on or off. In debugging mode, information is written to System.err to trace the process of deducing an encoding.

Parameters:

debug - set to true to enable debugging

resolve

public Reader resolve(URI absoluteURI,
                      String encoding,
                      Configuration config)
               throws XPathException

Resolve the URI passed to the XSLT unparsed-text() function, after resolving against the base URI.

Specified by:

resolve in interface UnparsedTextURIResolver

Parameters:

absoluteURI - the absolute URI obtained by resolving the supplied URI against the base URI

encoding - the encoding requested in the call of unparsed-text(), if any. Otherwise null.

config - The configuration. Provided in case the URI resolver needs it.

Returns:

a Reader, which Saxon will use to read the unparsed text. After the text has been read, the close() method of the Reader will be called.

Throws:

XPathException - if any failure occurs

Since:

8.9

inferStreamEncoding

public static String inferStreamEncoding(InputStream is,
                                         Logger err)
                                  throws IOException

Try to detect the encoding from the start of the input stream

Parameters:

is - the input stream

err - logger to be used for diagnostics, or null

Returns:

the inferred encoding, defaulting to UTF-8

Throws:

IOException - if it isn't possible to mark the current position on the input stream and read ahead
