Embodiment

The embodiment of the invention is given database with the Schema verification of XML information and is handled, promptly, to be converted to the list structure of database according to the XML tree of Schema structure, described XML information insertion is had in the database of described list structure, utilize the existing function check XML of database information whether to satisfy the code requirement of Schema.

The embodiment of the invention one specific implementation process comprises the steps: as shown in Figure 1

Step 1 is converted to the tree according to the XML of Schema structure that needs verification the list structure of database;

The characteristics of XML grammer are: an XML information is a tree that is made of series of elements, except root element, other element all has corresponding father's element, an element may exist 0 or a plurality of daughter element, therefore in fact constitute a reflexivity between the element entity among the XML, that is, father's element and daughter element are the relations more than 0 pair, all are elements and no matter father's element still is a daughter element itself; Element among the XML can have 0 or a plurality of attribute, and the relation between element entity and the attribute entities is the relation more than 0 pair;

According to the characteristics of above-mentioned XML grammer, construct database table structure as shown in the table:

Utilize above-mentioned list structure, the XML tree according to Schema structure can be converted between simple element entity and the attribute entities and corresponding linear relationship between the element entity;

Instantiation of described conversion process is as follows:

The Schema of an existing XML is defined as follows:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<xs:element?name＝″name″type＝″xs:string″/>

<xs:element?name＝″presence″>

<xs:complexType>

<xs:sequence>

<xs:element?ref＝″user″/>

</xs:sequence>

</xs:complexType>

</xs:element>

<xs:element?name＝″uri″type＝″xs:string″/>

<xs:element?name＝″user″>

<xs:complexType>

<xs:sequence>

<xs:element?ref＝″uri″/>

<xs:element?ref＝″name″/>

</xs:sequence>

</xs:complexType>

</xs:element>

</xs:schema>

A corresponding XML document is:

<？xml?version＝″1.0″encoding＝″UTF-8″？>

<presence>

<user>

<uri>sip:imsuser01＠cmcc.com</uri>

<name>cmcc</name>

</user>

</presence>

This Schema has a root element presence as can be seen, and this root element has a daughter element user, and two daughter element: uri and name are arranged under the user element, and being converted into like this will be as follows after the information in the database:

Component identification father component identification name-value

1 NULL presence NULL

2 1 user NULL

3 2 uri sip:imsuser01＠cmcc.com

4 2 name cmcc

Step 2 writes in the database with above-mentioned list structure the XML information after the above-mentioned conversion is top-down;

Because father's component identification is actually an external key of element entity in the list of elements, component identification in the attribute list is actually an external key of attribute entities, for satisfying the foreign key constraint requirement of data in the database, it is the master slave relation requirement, therefore must earlier the top layer element be inserted database, and then insert bottom element and corresponding attribute information thereof;

Step 3 utilizes the various tied mechanisms in the database to realize whether verification XML information satisfies the code requirement of Schema;

If in the process of an XML information completely being inserted database, failure occurs, illustrate that then the XML information of above-mentioned structure does not satisfy its Schema requirement, need re-construct; Otherwise then be correct.

Tied mechanism in the described database comprises: the relation of inclusion between the element is handled, satisfied to attribute and element in different ways, the value of some element can not can only can only be character string or the like for digital and/or some element value for empty, some value can only have an element, some element value.

Describedly utilize various tied mechanisms in the database to carry out verification in the checking procedure to go out XML information and do not satisfy the situation that its Schema requires and comprise: with attribute as unit usually handle, put upside down relation of inclusion between the element, can not for the value of the element of sky for empty, an element can only be arranged but not element, can only be nonnumeric for the value of the element of numeral and/or can only be non-character string or the like for the value of the element of character string.During insertion, when above-mentioned arbitrary situation occurring, then insert failure, show that described XML information does not satisfy the code requirement of Schema.

Step 4 when the described XML information of verification does not satisfy the code requirement of Schema, gives a warning, and the described XML information of prompting user does not satisfy the code requirement of Schema.This step is an optional step.

The embodiment of the invention two provides a kind of device of verification extend markup language Schema validity, and a kind of embodiment module diagram of described device comprises as shown in Figure 2:

The Schema modular converter is used for the XML according to the Schema structure is converted to database table structure;

XML information insert module is used for the top-down insertion of XML information after the described conversion is had the database of described list structure;

The verification module, the top-down insertion of XML information that is used for after described XML information insert module is with described conversion has the data base procedure of described list structure, utilizes the described XML information of the various constraint checkings of database whether to satisfy the code requirement of Schema.

Described device can further include:

Alert module is used to receive the check results of verification module, goes out in the calibration mode block check to give a warning when XML information does not satisfy the code requirement of Schema.

In sum, the embodiment of the invention has realized the Schema validity of verification XML, by the power of current database technology, checks the correctness of XML information easily and efficiently, when having guaranteed between process, to use XML to carry out interactive interfacing, make information satisfy the requirement of data legitimacy.

The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claim.
