Problem of shown/hidden element with if condition in xsl-CodePudding

I want to use if condition in below code.

    <xsl:variable name="vPageNumber"><fo:page-number/></xsl:variable>
    ...
    ..
    .
    <xsl:if test="$vPageNumber==1">
      <fo:block text-align="right" margin-right="24px">
        <fo:external-graphic content-width="20mm"  src="url(D:/Atlassian/images/Turkak.gif)" />
      </fo:block>
   </xsl:if>

Check if current page number is 1, this code block should be shown in header.If not code block should be hidden but it is not working. When we create pdf rendering from below code, Although current page number is 1 Turkak.gif is hidden in all of pages header. The full code is below.

<?xml version="1.0" encoding="ISO-8859-1"?>

#set($maxIssues = 500) ## set an upper limit for issues to be exported
#set($startIssuesOnNewPages = true) ## set to "true" to add a page break before each issue
#set($linkTypeNames = "Relates")    
#set($exportProjectAvatars = true) ## set to "true" to export project avatars for each issue
#set($exportThumbnails = true) ## set to "true" to export thumbnails of the image type attachments
#set($exportChangeHistory = $pdfView.name.contains('All')) ## set to "true" to export the issue field change history
#set($embedAttachments = true) ## set to "true" to include binary file attachments in the PDF document, see: https://www.midori-global.com/products/better-pdf-exporter-for-jira/server/documentation/embedding-attachments
#set($embeddedAttachmentMaxFileSize = 52428800) ## max filesize (bytes) for attachments to be embedded (default: 50M)
#set($hebele = 55555)

How i can this solve. Thanks in advice.

CodePudding user response：

I think you should investigate how to use fo:page-sequence-master instead; define a "first" page master which uses the header graphic, and a "remaining" page master without the graphic.

e.g. this might get you on the right track https://www.xmlpdf.com/different-first-page.html
