MetaData

public MetaData(Creation _c)

Method Detail

setFile

public void setFile(java.lang.String mf)

setFile - gives this MetaData object a file to parse cook local metadata into canonical form, and see what it matches in the Creation database. The local metadata is an XML string.

Parameters:

- - the XML file describing this work Note: a Side Effect is that authors extracted from the metadata are added to the Author database and to Creation c. Creation c is added to the Creation database if not previously there. Note: at present this procedure is invoked only by BibData.

getDOM

public static org.w3c.dom.Document getDOM(java.lang.String bytes)

getDOM - given an XML file of metadata as a byte[] array, construct a parse tree.

Parameters:

- - String is XML data to be parsed. returns Document representing the XML file.

getDate

public static java.lang.String getDate(java.lang.String url)

getDate - given an XML file of metadata return contents of a date entry

Parameters:

- - the URL of the metadata file

getValue

public static java.lang.String getValue(org.w3c.dom.Node nameNode)

getValue - give the name of a tag in an Element, return the element's value.

Parameters:

- - root Node of an XML subtree

- - the String which specifies the tag name returns a String which is the first value of the first tag with this name (or "");

getValue

public static java.lang.String getValue(org.w3c.dom.Document doc,
                                        java.lang.String name)

getValue - give the name of a tag in a Document, return the first value

Parameters:

- - doc is the Document object representing an XML tree

- - name -s the String which specifies the tag name returns a String which is the first value of the first tag with this name (or "");

getValues

public static java.lang.String[] getValues(org.w3c.dom.Document doc,
                                           java.lang.String name)

getValues - give the name of a tag in a Document, return all values

Parameters:

- - doc is the Document object representing an XML tree

- - name -s the String which specifies the tag name returns an array of Strings which are values of the first tag with this name (or null);

getAttr

public static java.lang.String getAttr(org.w3c.dom.Document doc,
                                       java.lang.String name,
                                       java.lang.String attr)

getAttr - Accesses a specific attribute of a specific node name

Parameters:

The - Document containing the XML tree

The - name of the node of interest
