Catalog resolvers are available for various programming languages. The following example shows how, in Java, a SAX parser may be created to parse some input source in which the org.apache.xml.resolver.tools.CatalogResolver is used to resolve external entities to locally cached instances
Together, the endpoint and the query string form a URL that determines how the API will respond. This URL is also known as a query or an API call. In the below example, two parameters are transmitted (or passed) to the API via the query string. The first is the required API key and the second is an optional parameter — the date of the ...
XPath (XML Path Language) is an expression language designed to support the query or transformation of XML documents. It was defined by the World Wide Web Consortium (W3C) in 1999, [1] and can be used to compute values (e.g., strings, numbers, or Boolean values) from the content of an XML document.
The event-driven model of SAX is useful for XML parsing, but it does have certain drawbacks. Virtually any kind of XML validation requires access to the document in full. . The most trivial example is that an attribute declared in the DTD to be of type IDREF, requires that there be only one element in the document that uses the same value for an ID attribu
the Document Object Model parsing interface or DOM interface; the Simple API for XML parsing interface or SAX interface; the Streaming API for XML or StAX interface (part of JDK 6; separate jar available for JDK 5) In addition to the parsing interfaces, the API provides an XSLT interface to provide data and structural transformations on an XML ...
A URI that links to a JSON document can specify a pointer to a specific value. [22] For example, a URL ending in #/foo could be used to extract the value from a key-value pair in a document beginning with { "foo": ["bar", "baz"], ... } In URIs for MIME application/pdf documents PDF viewers recognize a number of fragment identifiers.
Beautiful Soup is a Python package for parsing HTML and XML documents, including those with malformed markup. It creates a parse tree for documents that can be used to extract data from HTML, [3] which is useful for web scraping. [2] [4]
