The xsl:output element attributes omit-xml-declaration and method are
correctly set to "yes" and "text" respectively. My JSON result string
produced by the following code is prefaced by an XML declaration,
which is unwanted.
//Use the parsed stylesheet on the XML:
xmlDocPtr pDocOutput = xsltApplyStylesheet(cur,
const_cast<xmlDoc*>(xml_document.cobj()), 0);
xsltFreeStylesheet(cur);
//Get the output text:
xmlChar* buffer = 0;
int length = 0;
xmlIndentTreeOutput = 1; //Format the output with extra white
space. TODO: Is there a better way than this global variable?
xmlDocDumpFormatMemoryEnc(pDocOutput, &buffer, &length, 0, 0);
My result string is beginning with '<?xml version="1.0"
encoding="UTF-8"?>\n', not what I want. Same stylesheet (available at
http://www.xml.lt/static/files/xml2json.xsl) and xsltproc or
libxslt_tutorial.c from the libxslt website works fine.
I must be doing something wrong. Guidance?
Hi Al,
I don't know about C, but quite often when xsl:output isn't respected,
that means the XSLT serializer isn't in charge because you're outputting
the result to a document object - not to a buffer or a string. If you
want the XSLT serializer to be in charge, you must write to a buffer.
But I don't know how that translates to the C API.
In Perl, there are a couple of options:
* output_string(result)
* output_as_bytes(result)
* output_as_chars(result)
* output_fh(result, fh)
* output_file(result, filename)
What can be done in Perl definitely can be done in C.
Hope this helps.
Michael Ludwig
