XMLValidate

Description

This task checks xml files are valid (or only well formed). The task uses the SAX2 parser implementation provided by JAXP by default (probably the one that is used by Ant itself), but one can specify any SAX1/2 parser if needed.

This task supports the use of nested xmlcatalog elements and/or nested <dtd> elements which are used to resolve DTDs and entities.

Parameters

Attribute Description Required
file the file(s) you want to check. (optionally can use an embedded fileset) No
lenient if true, only check the xml document is well formed (ignored if the specified parser is as SAX1 parser) No
classname the parser to use. No
classpathref where to find the parser class. Optionally can use an embedded classpath element. No
failonerror fails on a error if set to true (defaults to true). No
warn log parser warn events. No

Nested Elements

dtd

<dtd> is used to specify different locations for DTD resolution.
Attribute Description Required
publicId Public ID of the DTD to resolve Yes
location Location of the DTD to use, which can be a file, a resource, or a URL Yes

xmlcatalog

The xmlcatalog element is used to perform Entity resolution.
