R: Parse an XML document with options controlling the parser.

xmlParseDoc {XML} | R Documentation

## Parse an XML document with options controlling the parser.

### Description

This function is a generalization of `xmlParse` that parses an XML document. With this function, we can specify a combination of different options that control the operation of the parser. The options control many different aspects the parsing process

### Usage

    xmlParseDoc(file, options = 1L, encoding = character(),
                asText = !file.exists(file), baseURL = file)

### Arguments

`file` | the name of the file or URL or the XML content itself
`options` | options controlling the behavior of the parser. One specifies the different options as elements of an integer vector. These are then bitwised OR'ed together. The possible options are `RECOVER`, `NOENT`, `DTDLOAD`, `DTDATTR`, `DTDVALID`, `NOERROR`, `NOWARNING`, `PEDANTIC`, `NOBLANKS`, `SAX1`, `XINCLUDE`, `NONET`, `NODICT`, `NSCLEAN`, `NOCDATA`, `NOXINNODE`, `COMPACT`, `OLD10`, `NOBASEFIX`, `HUGE`, `OLDSAX`. ( These options are also listed in the (non-exported) variable `parserOptions`.)
`encoding` | character string that provides the encoding of the document if it is not explicitly contained within the document itself.
`asText` | a logical value indicating whether `file` is the XML content (`TRUE`) or the name of a file or URL (`FALSE`)
`baseURL` | the base URL used for resolving relative documents, e.g. XIncludes. This is important if `file` is the actual XML content rather than a URL

### Value

An object of class `XMLInternalDocument`.

     f = system.file("exampleData", "mtcars.xml", package="XML")
         # Same as xmlParse()
     xmlParseDoc(f)

     txt =
         '<top xmlns:r="http://www.r-project.org">
            <b xmlns:r="http://www.r-project.org">
              <c xmlns:omg="http:/www.omegahat.net"/>
            </b>
          </top>'

     xmlParseDoc(txt,  NSCLEAN, asText = TRUE)

            </b>
          </top>'

     xmlParseDoc(txt, c(NSCLEAN, NOERROR), asText = TRUE)
