[XSL-LIST Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] regarding the extension library
 hello i have a question regarding using the extension library function ussage. i have seen articles that use the toUpperCase of String method in the following way. for xml <colors> <color>red</color> <color>blue</color> <color>green and pink</color> </colors> using the java's to upper case, the xsl would be <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan = "http://xml.apache.org/xalan" exclude-result-prefixes="xalan" xmlns:java = "java"> <xsl:template match="/"> <xsl:for-each select="/colors/color"> <xsl:variable name="color" select="java:lang.String.new(.)"/> from java: <xsl:value-of select="java:toUpperCase($color)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> where we instantiate the String object by saying java:lang.String.new() and then call the toUpperCase Method on that string. thaz fine. I have then formed my own utility class that returns the string in the uppercase( just for test purpose ). This Class is StrUtils which has a method called upperCase()that takes the String to be converted to the uppercase and returns String in uppercase. ( I am doing this purely for test purpose) and i am calling this method in the following way in my XSL <?xml version="1.0"?> <xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:xalan = "http://xml.apache.org/xalan" exclude-result-prefixes="xalan" xmlns:str-utils = "com.xyz.StrUtils" extension-element-prefixes ="str-utils" > <xsl:template match="/"> <xsl:for-each select="/colors/color"> <xsl:variable name="color" select="."/> <xsl:value-of select="str-utils:upperCase($color)"/> </xsl:for-each> </xsl:template> </xsl:stylesheet> This works fine too. My question is that in my Example, where is the instantiation being done?? I have not done anything like com.xyz.StrUtils.new()... so how is it working?? what is the theory behind the object instantiation when it comes to extension libraries?? i would be thankful if someone can please tell me about this. _________________________________________________________ Click below to visit monsterindia.com and review jobs in India or Abroad http://monsterindia.rediff.com/jobs XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
