February 18, 2014 · by · in Uncategorized · Leave a comment

Need
– Notepad++: http://notepad-plus-plus.org/
– XML Tool Plug-in: http://sourceforge.net/projects/npp-plugins/files/XML%20Tools/
– XSL, XPATH knowledge

Steps
– Open ejb-jar.xml using Notepad++
– (Limitation of XML plugin?) Trim all attributes from ejb-jar. Example:

<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

to

<ejb-jar>

– Open Plugins > XML Tools > XSL Transformation
– In the dialog box, browse and select the XLS file. In below sections, I provided 2 sample XLS file to extract out Name and Class of Entity Bean, Session Bean and Message-driven Bean and format to a CSV or HTML file.
– Click Transform
– A new document will be opened and filled with the transformed content

Sample XSL to extract to CSV file

<?xml version="1.0"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:template match="/">
		<xsl:for-each select="/ejb-jar/enterprise-beans/entity">
			<xsl:value-of select="ejb-name"/>
			<xsl:text>,</xsl:text>
			<xsl:value-of select="ejb-class"/>
			<xsl:text>,</xsl:text>
			<xsl:text>Entity Bean</xsl:text>
			<xsl:text>
</xsl:text>

		</xsl:for-each>

		<xsl:for-each select="/ejb-jar/enterprise-beans/session">

			<xsl:value-of select="ejb-name"/>
			<xsl:text>,</xsl:text>
			<xsl:value-of select="ejb-class"/>
			<xsl:text>,</xsl:text>
			<xsl:text>Session Bean</xsl:text>
			<xsl:text>
</xsl:text>

		</xsl:for-each>

		<xsl:for-each select="/ejb-jar/enterprise-beans/message-driven">

			<xsl:value-of select="ejb-name"/>
			<xsl:text>,</xsl:text>
			<xsl:value-of select="ejb-class"/>
			<xsl:text>,</xsl:text>
			<xsl:text>MDB</xsl:text>
			<xsl:text>
</xsl:text>

		</xsl:for-each>

	</xsl:template>

</xsl:stylesheet>

Sample XSL to extract to HTML file

<?xml version="1.0"?>

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
	<xsl:template match="/">

<html>
<head>
	<title>EJB names</title>
</head>
<body>
	<table>
		<tr>
			<td colspan="3"><strong>** ENTITY BEAN ** </strong></td>
		</tr>
		<xsl:for-each select="/ejb-jar/enterprise-beans/entity">
			<tr>
				<td><xsl:value-of select="ejb-name"/></td>
				<td><xsl:value-of select="ejb-class"/></td>
				<td>Entity Bean</td>

			</tr>
		</xsl:for-each>

		<tr>
			<td colspan="3"><strong>** SESSION BEAN ** </strong></td>
		</tr>
		<xsl:for-each select="/ejb-jar/enterprise-beans/session">
			<tr>
				<td><xsl:value-of select="ejb-name"/></td>
				<td><xsl:value-of select="ejb-class"/></td>
				<td>Session Bean</td>
			</tr>
		</xsl:for-each>

		<tr>
			<td colspan="3"><strong>** MESSAGE-DRIVEN BEAN ** </strong></td>
		</tr>
		<xsl:for-each select="/ejb-jar/enterprise-beans/message-driven">
			<tr>
				<td><xsl:value-of select="ejb-name"/></td>
				<td><xsl:value-of select="ejb-class"/></td>
				<td>MDB</td>
			</tr>
		</xsl:for-each>

	</table>
</body>
</html>

	</xsl:template>

</xsl:stylesheet>
