中國XML論壇看到有人問如何使用xquery，其實我也是個菜鳥。
剛剛運行了兩個例子，給不會的指個路。
首先下載saxon8.1.1
http://saxon.sourceforge.net/Saxon-B 8.1.1是免費的，Saxon-SA 8.1.1是有試用期的，前者就夠了。
系統(tǒng)要安裝jdk1.4.1以上版本，因為saxon是用這個版本寫的，但不知道1.3.1行不。
記得設(shè)置JAVA_HOME環(huán)境變量指向jdk。
然后，試試吧！
例子：文件characters.xml
<characters>
<character>
<name>Aleria</name>
<gender>Female</gender>
<species>Heroleim</species>
<vocation>Bard</vocation>
<level>5</level>
<health>25</health>
</character>
<character>
<name>Shar</name>
<gender>Male</gender>
<species>Human</species>
<vocation>Merchant</vocation>
<level>6</level>
<health>28</health>
</character>
<character>
<name>Gite</name>
<gender>Female</gender>
<species>Aelvar</species>
<vocation>Mage</vocation>
<level>7</level>
<health>18</health>
</character>
<character>
<name>Horukkan</name>
<gender>Male</gender>
<species>Udrecht</species>
<vocation>Warrior</vocation>
<level>5</level>
<health>32</health>
</character>
<character>
<name>Gounna</name>
<gender>Female</gender>
<species>Noleim</species>
<vocation>Mage</vocation>

<health>32</health>
</character>
<character>

<gender>Male</gender>
<species>Human</species>
<vocation>Merchant</vocation>
<level>5</level>
<health>24</health>
</character>
</characters>
查詢文件：Date.xquery
for $character in doc('characters.xml')//character
order by $character/name descending
return
<dateReport>
{$character/name}
</dateReport>

在命令提示下，輸入：
set classpath=d:\saxon\saxon8.jar （saxon8.jar所在文件夾）
java net.sf.saxon.Query -s characters.xml Date.xquery
ok!
看結(jié)果吧！
D:\xml>java net.sf.saxon.Query -s characters.xml Date.xquery
<?xml version="1.0" encoding="UTF-8"?>
