Annotation merge fails when xml tags are self-closing

[Aleks Clark]

This is valid XML:

<?xml version="1.0" encoding="UTF-8" ?>

<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">

<fields />

<annots>

<square subject="Rectangle" page="0" rect="266.400067,580.800145,415.560104,443.520111" name="787bc126-3c6d-a8f1-69ba-c32e691cb4c8" title="Guest" date="D:20140827054329-05'00'" color="#000000" interior-color="#FFFF00" width="3" creationdate="D:20140827054328-05'00'"/>

</annots>

<pages>

<defmtx matrix="1.333333,0,0,-1.333333,0,1056" />

</pages>

</xfdf>

And indeed, with a single annotation, this annotation is parsed and imported.

This is still valid XML:

<?xml version="1.0" encoding="UTF-8" ?>

<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">

<fields />

<annots>

<square subject="Rectangle" page="0" rect="266.400067,580.800145,415.560104,443.520111" name="787bc126-3c6d-a8f1-69ba-c32e691cb4c8" title="Guest" date="D:20140827054329-05'00'" color="#000000" interior-color="#FFFF00" width="3" creationdate="D:20140827054328-05'00'"/>

<line width="3" color="#000000" creationdate="D:20140826160542-05'00'" start="519.180000,557.040000" end="135.060000,270.600000" date="D:20140826160542-05'00'" name="9b1dfc01-eea0-10e3-9d8c-8ac1460e93fe" page="0" rect="135.060000,557.040000,519.180000,270.600000" subject="Line" title="Guest">

</line>

</annots>

<pages>

<defmtx matrix="1.333333,0,0,-1.333333,0,1056" />

</pages>

</xfdf>

But using the following code, you will only get the line annotation in your pdf:

pdf_doc = ex.doc

    pdf_doc.InitSecurityHandler()

    fdf_doc =FDFDoc.CreateFromXFDF(xfdf_string)

    pdf_doc.FDFMerge(fdf_doc)

    new_path = pdf_file_path + ".merge.pdf"

    pdf_doc.Save(new_path, SDFDoc::E_linearized)

By making the following change, you get both the line and the rectangle:

<?xml version="1.0" encoding="UTF-8" ?>

<xfdf xmlns="http://ns.adobe.com/xfdf/" xml:space="preserve">

<fields />

<annots>

<square subject="Rectangle" page="0" rect="266.400067,580.800145,415.560104,443.520111" name="787bc126-3c6d-a8f1-69ba-c32e691cb4c8" title="Guest" date="D:20140827054329-05'00'" color="#000000" interior-color="#FFFF00" width="3" creationdate="D:20140827054328-05'00'"></square>

<line width="3" color="#000000" creationdate="D:20140826160542-05'00'" start="519.180000,557.040000" end="135.060000,270.600000" date="D:20140826160542-05'00'" name="9b1dfc01-eea0-10e3-9d8c-8ac1460e93fe" page="0" rect="135.060000,557.040000,519.180000,270.600000" subject="Line" title="Guest">

</line>

</annots>

<pages>

<defmtx matrix="1.333333,0,0,-1.333333,0,1056" />

</pages>

</xfdf>

We're working around this, but this would seem to be a bug. Newer browsers (Chrome 37) will output the self-closing xml from the webviewer, while e.g. Chrome 33 does not, causing the issue.

Hello Aleks,

This issue was fixed earlier this month, with the fix available in the nightly builds:
