Abstract

A subscriber service for on-line document editing includes an Internet client in which a browser window is opened to begin XHTML editing, e.g., in Microsoft INTERNET EXPLORER. The text is transmitted to a host in a message over the Internet. In the host, a next process verifies this user has an account, or is otherwise authorized to use this site or access a particular document. A process receives the mal-formed XHTML typical of Microsoft INTERNET EXPLORER editing. A process cleans up this input, and converts it to fully formed XML, e.g., with TIDY freeware. A next process uses XSLT style sheets to transform the XML to LaTex source. Alternatively, the input is converted to Tex-type source lines. Another process includes a LaTex engine to typeset the input text according to the style sheets. Such produces a DVI-type output file. A next process converts the DVI to PDF. Commercial programs are available for this purpose. A process transmits the completed PDF file back to the client in a message. A next process at the client receives the PDF-formatted document. A further process allows such document to be printed at convenience. A final process notes the subscriber account at the host to track subscription charges and uses.

Claims

1. An Internet document service, comprising:

opening a browser window in an Internet client to begin document editing by accepting text input;

transmitting text to an Internet host in a message over the Internet;

receiving at said Internet host an XHTML text file from a client-browser editor;

converting said XHTML text file to a fully-formed XML;

using XSLT style sheets to transform said fully-formed XML to LaTex source;

typesetting with a Latex engine of said LaTex source input text according to said XSLT style sheets to produce an output file;

transmitting said output file back to the client in a message;

receiving said output file as a PDF-formatted document; and

printing said PDF-formatted document;

2. The service of claim 1, further comprising the steps of:

charging a user for the service of returning a ready-to-print PDF-formatted document based on said text input.

3. The service of claim 1, further comprising the steps of:

using TIDY freeware to assist in the step of converting said XHTML text file to a fully-formed XML.

4. The service of claim 1, further comprising the steps of:

allowing multiple users to access and edit a single one of said source input text with respective ones of said ready-to-print PDF-formatted documents being produced.

5. The service of claim 1, further comprising the steps of:

allowing multiple users to cooperatively access and edit a single one of said source input texts in a joint effort to generate a single one of said ready-to-print PDF-formatted document.

6. An Internet document service, comprising:

opening a browser window in an Internet client to begin document editing by accepting text input;

transmitting text to an Internet host in a message over the Internet;

verifying a user has an account, or is otherwise authorized to use said Internet host or to access a particular document;

receiving at said Internet host a mal-formed XHTML from Microsoft INTERNET EXPLORER editing;

cleaning up such mal-formed XHTML input and converting it to fully-formed XML;

using XSLT style sheets to transform said fully-formed XML to LaTex source;

typesetting with a LaTex engine of said LaTex source input text according to said XSLT style sheets to produce a DVI-type output file;

converting said DVI to a PDF file;

transmitting a completed PDF file back to the client in a message;

receiving said PDF file as a PDF-formatted document;

printing said PDF-formatted document; and

noting a subscriber account at said Internet host to track client-user subscription charges and accesses.

7. An Internet document service, comprising:

document editing in an Internet client browser window;

transmitting text collected in the step of document editing to an Internet host in a text file;

automatically typesetting a source input text from said text file according to style sheets to produce an output file;

transmitting from said Internet host said output file back to the client in a message;

receiving at said Internet client browser window said output file as a fully typeset and stylized PDF-formatted document; and

making said PDF-formatted document available for printing.

8. The Internet document service of claim 7, further comprising:

charging a service fee for the step of automatically typesetting.

9. The Internet document service of claim 7, further comprising:

screening out some of said text files before allowing the step of automatically typesetting.

10. The Internet document service of claim 7, further comprising:

correcting any file format problems in said text files before allowing the step of automatically typesetting.

11. The Internet document service of claim 7, further comprising:

correcting text or graphic content in said text files before allowing the step of automatically typesetting.

12. The Internet document service of claim 7, further comprising:

adding text or graphic content in said text files before allowing the step of automatically typesetting.

13. The Internet document service of claim 7, further comprising:

deleting text or graphic content in said text files before allowing the step of automatically typesetting.

14. The Internet document service of claim 7, further comprising:

broadcasting said fully typeset and stylized PDF-formatted document output file to a plurality of Internet clients with some common interest in such.
