Technical Field

The invention relates to the technical field of computers, in particular to a method and a device for generating an OFD format page based on an XML template.

Background

The OFD (Open file-layout Document, abbreviation: OFD) is the format of the format Document of our country defined by the national standard GB/T33190-2016 electronic file storage and exchange format Document of our country. The OFD meets the requirement of informatization construction in China, and is becoming one of the basic standards of informatization application of various industries in China. By the layout document, the page content described by the layout document has fixed appearance information such as position, size, color and the like, and the display effect of the page content on all terminals is completely fixed and consistent.

The OFD is a compressed package file in the ZIP compressed format with a file suffix ". OFD", so that the OFD is essentially a ZIP compressed package. According to the standard definition, the OFD contains two types of data files: a is the file and page information stored in XML format, it defines the basic information of the format file; and the other is resource information stored in other formats, such as a resource file in a font, an image, multimedia, and the like.

XML, Extensible Markup Language (XML), is an international popular universal data description Language format, and has many advantages such as simplicity, easy understanding, and easy application. The OFD adopts the basic information description format as a format document, and can be said to be the core data format of the OFD.

There is currently an important need in OFD format applications: it is necessary to generate files in a fixed layout format in batch, where the fixed layout format is the same but different in data content. In practical application, a large number of application scenarios exist, such as electronic invoices or electronic certificates, which are characterized in that the layout format is completely fixed, only the contents of the invoices or the certificates are different, and the applications need to be generated in a large number and for a long time. The existing solution is to directly generate the OFD full page data through a computer program, which needs to redesign and regenerate the computer program every time, and has complex application process and low execution efficiency.

Detailed Description

It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structures and implementation ways without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

An embodiment according to the present invention is shown in connection with fig. 1. A method for generating an OFD format page based on an XML template comprises the following steps:

s110: an XML template is obtained, the XML template including a series of metadata.

Specifically, each metadata includes the following information:

metadata names, each metadata name must be unique and readable character string.

Metadata values refer to data values defined by metadata.

The metadata type, which refers to a metadata value type, can be extended, such as text (i.e., character string), image, date, and the like.

Metadata positioning, which specifies the location and size (width, height) of metadata values within the layout page.

The metadata attribute is related to the metadata type, different types of attributes are set differently, for example, the metadata attribute of the text type has a font, a font size, a character color, a font style (bold, italic) and the like, and the data attribute of the image type can have a transparency or a rotation angle and the like.

As shown in fig. 2, before obtaining the XML template, the method further includes generating the XML template, and the specific steps are as follows:

and S210, acquiring original data.

And S220, respectively converting the original data into metadata according to the type of the original data. For the type of the original data being binary, the code conversion is needed to be performed, and the original data is converted into a data expression form conforming to the XML format standard, and the common code conversion is BASE-64, for example, the code conversion is needed for the data value of the image or the two-dimensional code type.

And S230, combining the plurality of metadata in sequence to generate the XML template.

In this embodiment, examples of the XML template metadata are as follows:

s120: the metadata is read in sequence, starting with the first piece of metadata of the XML template, one piece of metadata is read in sequence each time.

S130: and converting the metadata into an OFD file meeting the standard according to the type of the metadata, wherein the OFD file is required to be typeset, for example, the character type, then the position information of each character is acquired and output in an OFD form, and the image is output in the OFD form after the scaling and the rotation coefficient are calculated.

If the XML template contains data of a plurality of pages, processing of the next page is continued after one page is processed until the end.

S140: and outputting the OFD file.

According to the OFD standard, embedded fonts should be used for the archived OFD files to ensure that the OFD files are displayed identically on all platforms, so embedded fonts are used for files whose metadata type is text. The embedded font is to add character font data used in a designated font to the OFD file. The detailed processing procedure of the embedded font does not belong to the protection scope of the patent, and is not described herein.

It should be understood that the invention discloses a method for generating an OFD layout page based on an XML template, which helps an application person generate OFD files with the same layout display effect in batch. In batch generation, each piece of XML template metadata defines an OFD file, and the same generation process is executed, and the process is circulated until all the OFD files are generated. The XML template metadata may come from a database, from a network, or a combination of both or other data environments. The method can also be applied to format pages in PDF (Portable document Format) and other formats based on XML (extensive Makeup language) templates.

As shown in fig. 3 and fig. 4, the present invention also discloses a device for generating an OFD layout page based on an XML template, which includes:

an obtaining module 110, configured to obtain an XML template, where the XML template includes a series of metadata;
