Method and apparatus for processing XML for display on a mobile device
A method and apparatus are set forth for creating a Document Object Model of an XML document of predetermined type, comprising a first process for receiving and opening a compressed input file containing the XML document; a second process for opening and parsing the contents of a relationships file to create a map of name-value pairs and detecting a value for identifying the predetermined type from among a plurality of types of XML documents; and a further process for parsing data in the XML document according to the predetermined type, and building the Document Object Model.
1. A server for creating a Document Object Model of an XML document of predetermined type, comprising:
a memory; and
a processor configured to execute a distiller, said distiller comprising:
a first process for receiving and opening a compressed input file containing said XML document;
a second process for opening and parsing the contents of a relationships file to create a map of name-value pairs and detecting a value for identifying said predetermined type from among a plurality of types of XML documents, wherein said second process includes a Data XML Map class for detecting (i) a name-value pair with a value for identifying a Word™ 2007 XML file, (ii) a name-value pair with a value for identifying an Excel™ 2007 XML file and (iii) a name-value pair with a value for identifying a PowerPoint™ 2007 XML document; and
a further process for parsing data in said XML document according to said predetermined type, and building said Document Object Model for storage in said memory.
2. The server of claim 1 , wherein said first process is a ZIP file class for unzipping said compressed input file.
3. The server of claim 1 , wherein said further process includes a Data XML class.
4. The server of claim 1 , wherein said relationships file is an Office Open XML rels/.rels file.
5. The server of claim 1 , wherein said value for identifying a Word™ 2007 XML file is “word/document.xml”, said value for identifying an Excel™ 2007 XML file is “xl/workbook.xml”, and said value for identifying a PowerPoint™ 2007 XML document is “ppt/presentation.xml”.
6. A method of creating a Document Object Model of an XML document of predetermined type, comprising:
a first process for receiving and opening a compressed input file containing said XML document;
a second process for opening and parsing the contents of a relationships file to create a map of name-value pairs and detecting a value for identifying said predetermined type from among a plurality of types of XML documents, wherein said second process includes a Data XML Map class for detecting (i) a name-value pair with a value for identifying a Word™ 2007 XML file, (ii) a name-value pair with a value for identifying an Excel™ 2007 XML file and (iii) a name-value pair with a value for identifying a PowerPoint™ 2007 XML document; and
a further process for parsing data in said XML document according to said predetermined type, and building said Document Object Model.
7. The method of claim 6 , wherein said first process is a ZIP file class for unzipping said compressed input file.
8. The method of claim 6 , wherein said further process includes a Data XML class.
9. The method of claim 6 wherein said relationships file is an Office Open XML rels/.rels file.
10. The method of 1 , wherein said value for identifying a Word™ 2007 XML file is “word/document.xml”, said value for identifying an Excel™ 2007 XML file is “xl/workbook.xml”, and said value for identifying a PowerPoint™ 2007 XML document is “ppt/presentation.xml”.
