## Detailed Description

Class for XML documents.

This class encapsulates the access to the 'libxml' routines. Since the public interface of this class does not use any 'libxml' specific data structures it should be possible to replace the XML library with little effort (if required).

## Member Function Documentation

## ◆ checkNode()

OFCondition DSRXMLDocument::checkNode | ( | const DSRXMLCursor & | cursor,
|  | const char * | name ) const

check whether particular node matches a given name and report an error if not

Parameters

  cursor | cursor pointing to the particular node
  name | name of the node (XML element) to be checked

Returns
  OFTrue if name matches, OFFalse otherwise

## ◆ convertUtf8ToCharset()

OFBool DSRXMLDocument::convertUtf8ToCharset | ( | const xmlChar * | fromString,
|  | OFString & | toString ) const
| protected

convert given string from 'libxml' format (UTF8) to current character set

Parameters

  fromString | character string to be converted
  toString | reference to string object in which the result should be stored

Returns
  OFTrue if successful, OFFalse otherwise (e.g. no handler selected)

## ◆ encodingHandlerValid()

OFBool DSRXMLDocument::encodingHandlerValid | ( |  | ) | const

check whether the currently set character encoding handler is valid.

If no encoding handler is set this is equivalent to an invalid handler.

Returns
  OFTrue if handler is valid, OFFalse otherwise

## ◆ getElementFromAttribute()

OFCondition DSRXMLDocument::getElementFromAttribute | ( | const DSRXMLCursor & | cursor,
|  | DcmElement & | delem,
|  | const char * | name,
|  | const OFBool | encoding = OFFalse,
|  | const OFBool | required = OFTrue ) const

get element value from particular XML attribute

Parameters

  cursor | cursor pointing to the particular node
  delem | DICOM element in which the attribute value is stored
  name | name of the XML attribute to be retrieved
  encoding | use encoding handler if OFTrue, ignore character set otherwise
  required | flag specifying whether the attribute is required or not. If the attribute is required to be present an error message is reported in case it is not found.

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ getElementFromNodeContent()

OFCondition DSRXMLDocument::getElementFromNodeContent | ( | const DSRXMLCursor & | cursor,
|  | DcmElement & | delem,
|  | const char * | name = NULL,
|  | const OFBool | encoding = OFFalse ) const

get element value from particular XML element

Parameters

  cursor | cursor pointing to the particular node
  delem | DICOM element in which the element value is stored
  name | name of the XML element to be retrieved
  encoding | use encoding handler if OFTrue, ignore character set otherwise

Returns
  status, EC_Normal if successful, an error code otherwise

  cursor | cursor pointing to the particular node
  stringValue | reference to string object in which the value should be stored
  name | name of the XML attribute to be retrieved
  encoding | use encoding handler if OFTrue, ignore character set otherwise

get string value from particular XML element

Parameters

  cursor | cursor pointing to the particular node
  stringValue | reference to string object in which the value should be stored
  name | name of the XML element to be retrieved
  encoding | use encoding handler if OFTrue, ignore character set otherwise
  clearString | flag specifying whether to clear the 'stringValue' at first or not

Returns
  reference to string object (might be empty)

## ◆ getValueTypeFromNode()

E_ValueType DSRXMLDocument::getValueTypeFromNode | ( | const DSRXMLCursor & | cursor | ) | const

get value type from particular node.

The value type is either stored as the element name or in the attribute "valType". Additionally, by-reference relationships are also supported (either by attribute "ref" being present or element named "reference").

Parameters

  cursor | cursor pointing to the particular node

Returns
  value type (incl. by-reference) if successful, DSRTypes::VT_invalid otherwise

## ◆ hasAttribute()

OFBool DSRXMLDocument::hasAttribute | ( | const DSRXMLCursor & | cursor,
|  | const char * | name ) const

check whether particular node has a specific attribute

Parameters

  cursor | cursor pointing to the particular node
  name | name of the XML attribute to be checked

Returns
  OFTrue if attribute is present, OFFalse otherwise

## ◆ matchNode()

OFBool DSRXMLDocument::matchNode | ( | const DSRXMLCursor & | cursor,
|  | const char * | name ) const

check whether particular node matches a given name

Parameters

  cursor | cursor pointing to the particular node
  name | name of the node (XML element) to be checked

Returns
  OFTrue if name matches, OFFalse otherwise

## ◆ printGeneralNodeError()

void DSRXMLDocument::printGeneralNodeError | ( | const DSRXMLCursor & | cursor,
|  | const OFCondition & | result ) const

print general node error message

Parameters

  cursor | cursor pointing to the unexpected node
  result | status used to print details on the error (no message if EC_Normal)

## ◆ printMissingAttributeError()

void DSRXMLDocument::printMissingAttributeError | ( | const DSRXMLCursor & | cursor,
|  | const char * | name ) const
| protected

print error message for missing attribute

Parameters

  cursor | cursor pointing to the relevant node
  name | name of the XML attribute

## ◆ printMissingAttributeWarning()

void DSRXMLDocument::printMissingAttributeWarning | ( | const DSRXMLCursor & | cursor,
|  | const char * | name ) const

print warning message for missing attribute

Parameters

  cursor | cursor pointing to the relevant node
  name | name of the XML attribute

## ◆ printUnexpectedNodeWarning()

void DSRXMLDocument::printUnexpectedNodeWarning | ( | const DSRXMLCursor & | cursor | ) | const

print warning message for unexpected node

Parameters

  cursor | cursor pointing to the unexpected node

## ◆ read()

OFCondition DSRXMLDocument::read | ( | const OFString & | filename,
|  | const size_t | flags = 0 )

read XML document from file.

In order to enable the optional Schema validation the flag DSRTypes::XF_validateSchema has to be set.

Parameters

  filename | name of the file from which the XML document is read ("-" for stdin)
  flags | optional flag used to customize the reading process (see DSRTypes::XF_xxx)

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ setEncodingHandler()

OFCondition DSRXMLDocument::setEncodingHandler | ( | const char * | charset | ) |

set character encoding handler for converting internally stored character strings (UTF-8) to a particular character set.

This conversion is only done when requested, e.g. when calling getStringFromAttribute() with the 'encoding' parameter being OFTrue. NB: 'libxml' relies on GNU 'libiconv' for most character sets.

Parameters

  charset | XML name of the character set (e.g. "ISO-8859-1" for ISO Latin-1)

Returns
  status, EC_Normal if successful, an error code otherwise

## ◆ valid()

OFBool DSRXMLDocument::valid | ( |  | ) | const

check whether the current internal state is valid

Returns
  OFTrue if valid, OFFalse otherwise
