Description
Technical field
This application involves data processing fields, and in particular to a kind of processing method and system of masurium.
Background technique
Fig. 1 is the name definition exemplary diagram of each section in the XML element of the application.One complete message includes several embedding
The element of set, element are made of start-tag, element textual value and end-tag.Judge the member in an element in end-tag
Whether the masurium in plain name and start-tag matches, and is the necessary condition judged message and whether meet message specification, and firmware has
Obligation completes the judgement of masurium in element starting/end-tag.
Now with one section of XML message example:
Processing in firmware at present is one buffer area of distribution for caching masurium, and the masurium cached in buffer area is logical
It is often nested multiple masuriums.Fig. 2 is the data memory format schematic diagram of the masurium in buffer area, as shown in Fig. 2, XML
Storage format of the masurium of element in buffer area is TLV (Tag+Len+EName_n) cell format, and wherein Tag indicates current
The number of plies where element, Len indicate the length of currentElement name, and EName_n is the start-tag masurium of n-th layer element, and n is
Natural number.
Used system is hexadecimal when masurium caching.The initial value of buffer area is 0xFF, and Tag occupies a word
Section, Len occupy 2 bytes, and each masurium independently occupies TLV (Tag+Len+EName_n) unit, nested when occurring
When, it is necessary in continuous deposit buffer area, it is similar to pop down.When exiting n-th layer, by n-th layer masurium occupy in store
For 0xFF, continued to use in case subsequent.Below by taking above-mentioned XML message example as an example, to demonstrate the occupancy situation of masurium caching.
Fig. 3 is the schematic diagram of the Partial Elements name caching shown with above-mentioned message example.As shown in figure 3, buffer area institute energy
The masurium ability of receiving are as follows: (L0+3)+(L1+3)+... the memory of+(Ln+3)≤buffer area.The wherein Tag+ of 3B=1B
The Len of 2B, Li indicate the length of i-th of masurium.When memory in buffer area is fixed, include in the message that firmware can be handled
The number of plies of element number and nesting is limited solely by the length of each masurium.
The practical message issued of Internetbank control, can be because of buffer area when too long, the nested number of plies of individual element name is excessive
Limited memory, cause normal packet parsing to fail.
