[Experience Summary] implement Schema mode verification and XSLT template Conversion Based on libxml + libxslt on Windows Platform

Step 1: At this URL: http://xmlsoft.org/sources/win32/

Download these packages:

Iconv-1.9.2.win32.zip

Libxml2-2.7.3.win32.zip

Libxslt-1.1.24.win32.zip

Copy the Lib, DLL, and include files to the appropriate location.

 

Step 2:

Compile the test code:

XML Schema:

<Br/> # include "libxml/tree. H "<br/> # include" libxml/parser. H "<br/> # include" libxml/xmlschemas. H "</P> <p> /****************************** * ******************** <br/> @ describle application XML Schema template file verification case document <br/> @ paramschema_filename mode file <br/> @ paramxmldoc case file in XML format <br/> @ retval> = 0 Verification Successful <br/> <0 Verification Failed <br/> ** **************************************** * *********/<br/> int is_valid (const char * schema_filename, const char * xmldoc) {<br/> xmldocptr Doc; <br/> Doc = xmlreadfile (xmldoc, null, xml_parse_nonet | xml_parse_noent ); <br/> If (null = DOC) {<br/> MessageBox (null, "XML document read error", null, null); <br/> return-1; <br/>}< br/> xmldocptr schema_doc = xmlreadfile (schema_filename, null, xml_parse_nonet | xml_parse_noent); <br/> If (null = schema_doc) {<br/> MessageBox (null, "schema read error", null, null); <br/> return-1; <br/>}< br/> xmlschemaparserctxtptr parser_ctxt = xmlschemanewdocparserctxt (schema_doc); <br/> If (null = parser_ctxt) {<br/> return-1; <br/>}< br/> xmlschemaptr schema = xmlschemaparse (parser_ctxt); <br/> If (schema = NULL) {<br/> return-1; <br/>}< br/> xmlschemavalidctxtptr valid_ctxt = xmlschemanewvalidctxt (schema); <br/> If (null = valid_ctxt) {<br/> return-1; <br/>}< br/> int is_valid = (xmlschemavalidatedoc (valid_ctxt, DOC) = 0); </P> <p> xmlschemafreevalidctxt (valid_ctxt ); <br/> xmlschemafree (schema); <br/> xmlschemafreeparserctxt (parser_ctxt); <br/> xmlfreedoc (schema_doc); </P> <p> return is_valid; <br/>}
