我想用java工具SAXON我需要什麼使用Saxon java工具(命令行)從xsl查詢mysql數據庫?
- 使用ODBC連接到數據庫查詢連接到MySQL數據庫
- 查詢數據庫(可能是信息架構 - 讀取模式)
- 將結果導出到XML
這是撒克遜許可的功能(例如saxon9ee)嗎?
如果是有沒有其他的開源選項來實現相同級別的功能?
我已經下載了saxon9ee.jar + saxon9he.jar並玩了一下。
是我迄今所做的:
XSLT:connect.xslt
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
xmlns:xs="http://www.w3.org/2001/XMLSchema"
exclude-result-prefixes="#all"
xmlns:sql="http://saxon.sf.net/sql"
extension-element-prefixes="sql"
version="2.0">
<xsl:output method="xml" encoding="UTF-8" indent="yes"/>
<xsl:param name="driver" select="'com.mysql.jdbc.Driver'"/>
<xsl:param name="database" select="'jdbc:mysql://localhost/databaename'"/>
<xsl:param name="user" select="'usr'"/>
<xsl:param name="password" select="'pwd'"/>
<xsl:template match="//databaseObjects">
<xsl:message>Connecting to database...</xsl:message>
<!-- The "connection" variable establishes JDBC connection by selecting as its value the SQL connection to the database.!-->
<xsl:variable name="connection" as="java:java.lang.Object" xmlns:java="http://saxon.sf.net/java-type">
<sql:connect driver="{$driver}" database="{$database}" user="{$user}" password="{$password}">
<!-- Used primarily for debugging, if,
for whatever reason, the credentials or something incorrect is passed in the connect statement,
the process will terminate with the following message -->
<xsl:fallback>
<xsl:message terminate="yes">Connection to MySQL failed.</xsl:message>
</xsl:fallback>
</sql:connect>
</xsl:variable>
<sql:close connection="$connection"/>
</xsl:template>
</xsl:stylesheet>
XML:objects.xml
(粗略的想法)
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<databaseObjects>
<object type="triggers"/>
<object type="functions"/>
<object type="procedures"/>
<object type="views"/>
<object type="events"/>
</databaseObjects>
命令:
java -jar ~/saxon/saxon9he.jar objects.xml connect.xslt
輸出:
No license file found - running with licensable features disabled Connecting to database... Error on line 17 of connect.xslt: XTDE1450: Unknown extension instruction in built-in template rule Transformation failed: Run-time errors were reported
任何形式的幫助是明顯的,由於
的SQL擴展,不提供在撒克遜HE:http://www.saxonica.com/feature-matrix.html。 – mzjn
撒克遜EE呢,還有什麼其他選擇? – sakhunzai
@mzjn謝謝,我正在尋找開源解決方案,在這種情況下 – sakhunzai
