Dtd validation with libxml2

问题:

how do i do dtd validation with libxml2? i am reading my xml file using the reader api. i have an external dtd validation file. how do i perform the validation itself? do i have to convert it to xsd?

回答1:

Use xmlValidateDtd api, as described in FAQ, point 11.

This function is used by xmllint application, when --dtdvalid is supplied. See the source file, xmllint.c, parseAndPrintFile function. Search for xmlValidateDtd, it's used only once now.

If your are using python as your programming language, try using lxml. This has in-built implementation of libxml2 which is pretty neat in XML DTD validation. And it provides a lot of information which can be helpful in debugging the dtd or xml file.
