org.vishia.xmlSimple.Xsltpre

public class Xsltpre
extends java.lang.Object

This class is the wrapper for the command line invokation of a XSLT preprocessor for text output. The intension of preprocessing a XSLT script is shown in followed:
For text output, it is convenient for software support to write the lines in XSL script in the order of the output file. But if some informations from XML are merged in them, the necessitative expression may be a little long and not clearly. A short form will be better.
The class converts the given script line per line, it is a simple displacement of textual parts, combined with the possibility of alias names especially for XPATH expressions.
The key strings of special expressions begin with the <-character like XML, but followed by a special character outside the XML possibilities. So it is plain detectable by human in the script and non-ambiguous detectable by the conversion routine. The followed expressions will be detected and converted:

(?=ident=XPATH?)	The XPATH expression is stored and assigned to the alias ident.
(?!path?)	Value of the element or attribut given by expression. path is either a XPATH expression or, if starting with = an alias representing a XPATH. The resulting code in XSLT is: </xsl:text><xsl:value-of select="path" /><xsl:text>
(?:name[:path](parameter=value, ...)?)	call of the named template name with selecting the path before, with the named parameter with theire given value. The path should be written in "" if it is given directly. The path may be given also as alias, if started with =. The value of the parameters may be given as followed: *xpath A XPATH expression =alias A XPATH expression given with the alias 'text' A constant text expression. Some expressions may be concated with " + ". See example. If no parameter are given, write (). Separate parameters with a colon ,. The resulting code in XSLT is: </xsl:text><xsl:for-each select="path"> <xsl:call-template name="name"> <xsl:with-param name="parameter">...(value)</xsl:with-param> </xsl:call-template> <xsl:text> If no path is given by writing <:path:name(..., no <xsl:for-each ... wrapping is done.

Example:
The code (TODO!!!)

(?=myPath=element1/element2/@value?)
 ...<xsl:text>
 The text with info:(?@=myPath?) and info2:(?@attrib?) is written
 with (?:callname()?) and with (?:callname2:"callpath"(par1='text' + xxx)?)</xsl:text>
 

is converted to

 ... TODO
