Reading distributed/interrupted instructions of field codes causes an exception

[byteSamurai]

I just stumbled upon an issue. Given this markup from a off-the-shelf Word document:

<w:r w:rsidR="006B53C8">
    <w:fldChar w:fldCharType="begin" />
</w:r>
<w:r w:rsidR="006B53C8">
    <w:instrText xml:space="preserve"> XE "</w:instrText>
</w:r>
<w:r w:rsidR="006B53C8" w:rsidRPr="00D01158">
    <w:instrText>Introduction</w:instrText>
</w:r>
<w:r w:rsidR="006B53C8">
    <w:instrText xml:space="preserve">" </w:instrText>
</w:r>
<w:r w:rsidR="006B53C8">
    <w:fldChar w:fldCharType="end" />
</w:r>

From the document:

Expected Behaviour

The instruction text will be concatenated to form the string XE "Introduction"

Actual Behaviour

An Exception will be thrown, because the detected fieldCode is just XE ":

Unhandled exception. System.NotImplementedException: The missing part """ of the field code "XE "" couldn't be processed by the Parser

   at OfficeIMO.Word.WordField.get_FieldType() in /home/f/OfficeIMO/OfficeIMO.Word/WordField.cs:line 107

Possible Fix Suggestions

• Improve the reading/parsing of the document regarding field codes
• Replace the exception with an Console Warning and work with incorrectly read/parsed document

Option 1, of course.

Okay, on it.

Tests would be good for this case. Leaving it open unless you think it's not needed.
