When editing the arguments of an XPath/XSLT function, Oxygen XML Editor plugin tracks the current entered argument by displaying a tooltip containing the function signature. The currently edited argument is highlighted with a bolder font.
When moving the caret through the expression, the tooltip is updated to reflect the argument found at the caret position.
We want to concatenate the absolute values of two variables, named v1 and v2.
<xsl:template match="/"> <xsl:value-of select="concat(abs($v1), abs($v2))"></xsl:value-of> </xsl:template>When moving the caret before the first abs function, Oxygen XML Editor plugin identifies it as the first argument of the concat function. The tooltip shows in bold font the following information about the first argument:
XPath Tooltip Helper - Identify the concat Function's First Argument
XPath Tooltip Helper - Identify the abs Function's Argument
XPath Tooltip Helper - Identify the concat Function's Second Argument
The tooltip helper is available also in the XPath toolbar and the XPath Builder view.
