[SOLVED] C program to filter elements of type anyURI from string XML using XSLT

C program to filter elements of type anyURI from string XML using XSLT

I have a XML string, I want to apply XSLT string on this XML to filter elements of type anyURI.

I am interested to use libxslt. But It transforms the xml present in file. I want to transform xml string.

How to write a C program to transform this xml string?

Solution

In terms of XSLT, libxslt is an XSLT 1.0 processor so it doesn't support W3C schema types like xs:anyURI in XSLT, you would need to use an XSLT 2 or 3 processor. Therefore I am not sure how you expect your XSLT program, whether you have it in a file or in a string, to filter out elements of type xs:anyURI.

In terms of C, I guess, depending on your "string" representation, you need to use http://www.xmlsoft.org/html/libxml-parser.html#xmlReadMemory or xmlReadDoc to get an http://www.xmlsoft.org/html/libxml-tree.html#xmlDocPtr for both the XML "string" input and the XSLT "string" input and then the libxslt APIs allow you to use http://xmlsoft.org/XSLT/html/libxslt-xsltInternals.html#xsltParseStylesheetDoc to get an xsltStylesheetPtr and then to run xsltApplyStylesheet.
