I think the beginner's errors may be approached:

1. XML 鏄笉鏄?HTML 鐨勫彇浠ｈ?

2. XML is not a replacement for the database

涓嶆槸銆?br />
3. XML is not a replacement of ...

Not.

This conclusion may sound funny: XML is a very, very important thing, but it can not replace anything.浣嗚繖骞朵笉濂囨?锛屾湁浜烘妸瀹冩瘮鍋?ASCII 鏍囧噯锛屼粬浠槸涓?垏涓?垏鐨勫熀纭?紝浣嗗苟娌℃湁锛堜篃涓嶉渶瑕侊級鍙栦唬浠?箞銆?锛堜絾鏄氨濡傚悓 ASCII 鍙栦唬浜嗕竴浜涙病鏈夋垚澶у櫒鐨勫瓧绗﹂泦瀹氫箟锛孹ML 涔熶細鍙栦唬浣犲湪搴旂敤涓嚜宸卞畾涔夌殑涓?簺鏁版嵁浼犺緭瑙勮寖锛屼絾娌℃湁浠?箞鐗瑰埆涓绘祦鐨勪笢瑗裤?锛?br />
Just started learning XML (or do not start school before) when the favorite to ask a question must be: using XML give me any good?

- Once upon a real understanding, even if no xml parser, does not prevent you from using this concept, as you can set aside a specific language to use OO.

Seem more abstract and Mo Puer instead.

Etc.

Not always add a function, again on the re-definition of the function. So the simplest way is to combine them as a parameter to the function.鍦ㄦ湁 xml 涔嬪墠锛屼綘鍙兘浼氫娇鐢ㄥ垎闅旂锛歴tr = "鍙戣█浜?寮犱笁;瀵嗙爜=**锛涙爣棰?abc锛涘唴瀹?xyz"

This method of passing the string there are several issues, summarized the two largest areas are:

1. To properly analyze it too much trouble. (Eg, just the title is "The spokesman = Joe Smith;" how to do)
2. Is flat, not hierarchical structure

Enough! Zan is it with XML. In my current knowledge in simple and obvious:

- XML is used to transfer data
- XML data with these structures - a tree structure
- Xml with a full set of operation method of this structure

- Xml specification (or the actual point, xml parser) in a way to verify the legitimacy of
- For the server component to get this string is, you can use xml in the ready-made way to operate it,
杩欏氨鏄?xpath, pattern锛岀被浼间簬 T-SQL 璇彞銆?(But keep in mind is the tree structure of xml)
- XSLT convert xml using xpath on (similar to DTS), which is a special case of the XML into HTML output.

"Rise" magician / Swordsman bred Guide

Introduction: ah .... the first to say sorry, because the killing floor two days out of a big update to accidentally indulged into, and with a game I run another story to remind ourselves to avoid mistakes So these two days is not updated ...

However, to compensate, I will try to release tomorrow, the whole of Chapter 2.

Introduction 2: Yes, there are two customs clearance foreword ... this again when I practiced a Mo Jianshi, so we can fit the two magicians and swordsmen.

First of all, or practice before the state clearance.

Swordsman points:

This game is the most average of close weapons capability

Swords can be used beginning with shield, with a single hand can be used to upgrade the skills handed sword type weapons (6 and 9)

But the attack speed is not fast, was Dangge slow speed when the back is very easy to eat each other's counter-technology.

Swordsman breeding lines:

Frankly speaking, the capacity of the sword is too strong .........

Basically there is no particular need attention.

Skills first and then upgrade to the three main forces can add to the strength of 100 plus skills right after.

Magician points:

wisdom without having to spend points, but the reading and stone (stone plate) increased.

Favor a long-career, like a bow and arrow like magic, need to manually aim.

Magic will not return as time passed and must be water, or sleep medication.

Sword and Axe skills limit is 7, to teach high-level skills will not bother you .........

Please decide if one of the magic for specialization, the other with a small practice, too many choices will only make their rush it.

Mo Jianshi points:

In addition to the above mentioned items, pay attention to road warriors actually take the order is more appropriate when Mo Jianshi, for close combat skills will not be as limited as the magician. (Though I was taking this Mo Jianshi Master line, but not difference.)

Has a magician's attack power, but also swordsmen strong melee ability, but attack power lower than that of pure swordsman. However, the sword buckle down 80% and 60% of it is not much difference, it is also hit Siya.

Magician / Mo Jianshi bred lines:

From the beginning, first add the power of 30, added 3 sword skills to ensure a certain amount of close combat ability, or will be miserable in the beginning.

In addition to sneak unlock, other points remain to learn magic, when it first entered Chapter 2, specialization of the project should be around 6-7 levels, is sufficient.

Fireball (fire ball), the highest single attack power, but the scope of damage, can not directly hit, but the firing capacity is relatively low.

Magic Missile (magic bullet), single attack power is low, the scope of small, hit a relatively high demand, but in bursts of competent.

Ice Lance (ice lance), attack power is not high, firing capacity is not high, and the opener long time, but has some chance of freezing enemies to live, how you fish.

In fact, three kinds of magic has its own advantages, but are simply practicing magician, then invited his fireball or magic missile, because the ice is not suitable for the gun.

Instead Mo Jianshi no problem with what.

After entering Chapter 2,

Magician, then the specialization skills to fill, and then add alchemists and two blacksmiths, to create their own syrup and processing power plus 20 mana of the ring, then all points are placed on the right mana.

Mo Jianshi, then fill first magic specialization, and alchemists, together with sword skills, enough to power by medicine, coupled with additional mana of the ring.

If the Master line of Mo Jianshi go to Chapter 3 of the second half took the necklace add mana to throw a ring, and then accompanied by two plus one of the ring fencing, we can take Shuangshoujian the.
