The Xerces Java Parser 1.4.4 supports the XML 1.0 recommendation and contains advanced parser functionality, such as support for the W3C's XML Schema recommendation version 1.0, DOM Level 2 version 1.0, and SAX Version 2, in addition to supporting the industry-standard DOM Level 1 and SAX version 1 APIs.
If there are associated attributes, then the first list member will be a list containing a symbol followed by two list members for each associated attribute; the first member is a symbol representing the attribute, and the next member is a string corresponding to the attribute value. By default, parse-xml outputs a DTD parse along with the parsed XML contents. The following example shows DTD parsed output components: ") (defun example-callback (var-name token &optional public) (declare (ignorable token public)) (setf var-name (uri-path var-name)) (if* (equal var-name "null") then nil else (let ((string (eval (intern var-name (find-package :user))))) (make-string-input-stream string)))) (defvar *xml-example-string* " ((:xml :version "1.0" :encoding "utf-8") (:comment " the following XML input is well-formed but may or may not be valid ") (:pi :piexample "this is an example processing instruction tag ") (: DOCTYPE :example (:[ (: ELEMENT :item1 (:choice (:* :item2) (:seq (: :item3) :item4))) (: ELEMENT :item2 : ANY) (: ELEMENT :item3 : PCDATA) (: ELEMENT :item4 : PCDATA) (: ATTLIST item1 (att1 : CDATA : FIXED "att1-default") (att2 : ID : REQUIRED) (att3 (:enumeration :one :two :three) "one") (att4 (: NOTATION :four :five) "four")) (: ENTITY :param1 :param "text") (: ENTITY :nentity : SYSTEM "null" : NDATA :somedata) (: NOTATION :notation : SYSTEM "notation-processor")) (:external (: ENTITY :ext1 "this is some external entity text"))) ((item1 att1 "att1-default" att2 "1" att3 "one" att4 "four") (item3 "this is some external entity text"))) Allegro CL also offers a SAX parser (described in sax.htm).
There is a PXML-SAX compatibility package (see the LXML section in sax.htm). parse-xml requires Modern Lisp's mixed case and international character support 2. parse-xml, the XML Namespace specification, and packages 4.
Every sample program and exercise adheres to W3C and . The course is intended for experienced software developers with a working knowledge of XML, and familiarity with DTDs or XML Schema, who want to build XML applications or components using Microsoft's . Upon completion of this course, participants will be able to create XML applications in . NET technologies to meet the application program's requirements.
Neko Pull is an XML document parsing API that extends the Xerces Native Interface (XNI) to provide pull parsing functionality.they are stateless and traverse the , here's how: Alternatively, you may wish to attach validators directly to the SAMLObject and evaluate them at some point later.Introduction and a simple example LXML parse output format parse-xml non-validating parser properties PXML compatibility with the SAX parser Usage notes parse-xml requires Modern Lisp's mixed case and international character support parse-xml and packages parse-xml, the XML Namespace specification, and packages The parse-xml function has been tested ACL does not support Unicode 4 byte scalar values debugging aids XML Conformance test results parse-xml reference *debug-xml* *debug-dtd* More on members of type # 2: if the XML tag does not have associated attributes, then the first list member will be a symbol representing the XML tag, and the other elements will represent the content, which can be a string (text content), a symbol (XML tag with no attributes or content), or list (nested XML tag with associated attributes and/or content). When processing valid XML input, parse-xml will optionally produce the same output as a validating parser would, including the processing of an external DTD subset and external entity declarations.Piccolo is a small, extremely fast XML parser for Java.It implements the SAX 1, SAX 2.0.1, and JAXP 1.1 (SAX parsing only) interfaces as a non-validating parser and attempts to detect all XML well-formedness errors. It is fully conforming: it detects all non well-formed documents. However it can parse all external entities: external DTD subsets, external parameter entities and external general entities.

And also, this is NOT correct: "If you just need to check if XML file is well formed, successful loading into XMLReader object is usually enough." It is not enough.
