XML format for SQL sentences

> I create this thread just for discussing about how would be the tags set and the structure for the XML file which will be use in SQL queries. 

Tonight I and Denis finished translating core to DOMDocument.
And now I can start writing documentation.

All simple tags we are have. For example:
        <update name="personal" table="user_info" action="post:save">
            <about is="post:about" nl2br="true" match=".+" />
            <birthday is="post:birthday" match="[0-9]{1,4}" />
            <marriage is="post:marriage" match="[0-3]" />
            <city_id is="post:city_id" match="[0-9]{1,3}" />
            <smoke_id is="post:smoke_id" match="[0-3]" />
            <alko_id is="post:alko_id" match="[0-3]" />
            <grant_id is="post:grant_id" match="[0-3]" />
            <meet_place_id is="post:meet_place_id" match="[0-3]" />
            <where>
                <and>

                <id is="class:user|id" match="[0-9]+"/>

                </and>   
                <and>

                <dir is="0" match=".+"/>

                </and>                       
            </where>
        </update>
        <select name="userinfo" table="user_info">
            <allfields />
            <join from="cities" type="left" key="city_id">
                <name as="city" />
            </join>
            <where>
                <and>

                <id is="class:user|id" match="[0-9]+"/>

                </and>   
                <and>

                <dir in="0,1" match=".+"/>

                </and>                       
            </where>
        </select>
        <select name="cities" table="cities">
            <allfields />
        </select>

> I think it would be great to use the same XML format for multi-threading and simple SQL queries. 

Yep, multi-threading is very important feature.
And with new core it will be more simple.

I hope commit new core to SVN tonight.

Yes you are right, PHP multithreading is not available for windows, just for unix like OS. Maybe in the future...
