After skimming xmllint.c I want to confirm that my understanding of the following is correct. 1) The only way to use xmllint to validate against an external DTD file is xmllint --dtdvalid luddite.dtd file1.xml file2.xml ... and the following will not work as neither `testSAX()` nor `streamFile()` validate against an external DTD file: xmllint --sax --dtdvalid luddite.dtd file1.xml ... xmllint --stream --dtdvalid luddite.dtd file1.xml ... 2) Does the following mean that when using libxml2's SAX functionality a document representation of the entire input XML is created in memory? http://git.gnome.org/browse/libxml2/tree/xmllint.c#n1711 3) As of v2.7.8 and using the Reader API, there is no way to validate using an external DTD similar to http://git.gnome.org/browse/libxml2/tree/xmllint.c#n1881 http://git.gnome.org/browse/libxml2/tree/xmllint.c#n1896 4) As of v2.7.8 and using the Reader API, there is no way to a posteriori validate using an external DTD similar the following. A posteriori DTD validation is only available after parsing a full DOM into memory. http://git.gnome.org/browse/libxml2/tree/xmllint.c#n2759 If the above are correct, what do you suggest to people who want to use libxml2 to validate large XMLs with external DTD files? Re-write the input XML file?
