c# - Excel OpenXml Workbook类中xmlelements的特定顺序

c# - Excel OpenXml Workbook类中xmlelements的特定顺序,第1张

我通过OpenXml创建PowerPoint演示文稿。演示文稿的幻灯片中充满了嵌入式对象。通常嵌入Excel文档。除了准备嵌入图像和文档之外,Excel还需要另一个信息,当在PowerPoint中打开文档时,该区域将显示给用户。

通过将OleSize类添加到工作簿部分,可以将此信息添加到Excel工作簿中。请忽略此代码不会检查该片段的存在,这肯定会导致问题。这只是一个简单的例子。

    var oleSize = new OleSize() {Reference = "A1:H12"};
    var workbook = document.WorkbookPart.Workbook;
    workbook.Append(oleSize);

当刚刚添加到工作簿类的OpenXmlElements列表的末尾时,Excel将显示一条错误消息对话框,指出该文件已损坏,无法修复。在PivotCache之后直接放置此元素OpenXmlElement可以作为一种解决方法。现在我体验到,当OleSize之前的OpenXmlElement可用时,Excel也会引发该消息。

我无法找到有关该特定类的OpenXmlElements订单必要性的任何信息。

任何提示都受到高度赞赏。

您对答案中列出的顺序是对的。在您所引用的OpenXML规范文档中,Workbook有一个XSD(第3936页),表明订单确实是强制性的,因为它被定义为Sequence

<xsd:complexType name="CT_Workbook">
    <xsd:sequence>
        <xsd:element name="fileVersion" type="CT_FileVersion" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="fileSharing" type="CT_FileSharing" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="workbookPr" type="CT_WorkbookPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="workbookProtection" type="CT_WorkbookProtection" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="bookViews" type="CT_BookViews" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="sheets" type="CT_Sheets" minOccurs="1" maxOccurs="1"/>
        <xsd:element name="functionGroups" type="CT_FunctionGroups" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="externalReferences" type="CT_ExternalReferences" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="definedNames" type="CT_DefinedNames" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="calcPr" type="CT_CalcPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="oleSize" type="CT_OleSize" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="customWorkbookViews" type="CT_CustomWorkbookViews" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="pivotCaches" type="CT_PivotCaches" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="smartTagPr" type="CT_SmartTagPr" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="smartTagTypes" type="CT_SmartTagTypes" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="webPublishing" type="CT_WebPublishing" minOccurs="4129 0" maxOccurs="1"/>
        <xsd:element name="fileRecoveryPr" type="CT_FileRecoveryPr" minOccurs="0" maxOccurs="unbounded"/>
        <xsd:element name="webPublishObjects" type="CT_WebPublishObjects" minOccurs="0" maxOccurs="1"/>
        <xsd:element name="extLst" type="CT_ExtensionList" minOccurs="0" maxOccurs="1"/>
    </xsd:sequence>
    <xsd:attribute name="conformance" type="s:ST_ConformanceClass"/>
</xsd:complexType>

如果您有兴趣,我会得到一个答案here,其中显示了将项目添加到文件中正确位置的一种方法。

答案 1 :(得分:0)

深入研究OpenXml规范第4版后,我发现了这些信息:

sml_CT_Workbook =
     4261 attribute conformance { s_ST_ConformanceClass }?,
     4262 element fileVersion { sml_CT_FileVersion }?,
     4263 element fileSharing { sml_CT_FileSharing }?,
     4264 element workbookPr { sml_CT_WorkbookPr }?,
     4265 element workbookProtection { sml_CT_WorkbookProtection }?,
     4266 element bookViews { sml_CT_BookViews }?,
     4267 element sheets { sml_CT_Sheets },
     4268 element functionGroups { sml_CT_FunctionGroups }?,
     4269 element externalReferences { sml_CT_ExternalReferences }?,
     4270 element definedNames { sml_CT_DefinedNames }?,
     4271 element calcPr { sml_CT_CalcPr }?,
     4272 element oleSize { sml_CT_OleSize }?,
     4273 element customWorkbookViews { sml_CT_CustomWorkbookViews }?,
     4274 element pivotCaches { sml_CT_PivotCaches }?,
     4275 element smartTagPr { sml_CT_SmartTagPr }?,
     4276 element smartTagTypes { sml_CT_SmartTagTypes }?,
     4277 element webPublishing { sml_CT_WebPublishing }?,
     4278 element fileRecoveryPr { sml_CT_FileRecoveryPr }*,
     4279 element webPublishObjects { sml_CT_WebPublishObjects }?,
     4280 element extLst { sml_CT_ExtensionList }?

没有信息,如果这是garantueed或预期的订单,但只有几个测试它看起来很有希望(我检查该订单的测试工作簿之一的工作簿openxml片段)

<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<x:workbook xmlns:x15ac="http://schemas.microsoft.com/office/spreadsheetml/2010/11/ac" xmlns:r="http://schemas.openxmlformats.org/officeDocument/2006/relationships" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" xmlns:x15="http://schemas.microsoft.com/office/spreadsheetml/2010/11/main" mc:Ignorable="x15" xmlns:x="http://schemas.openxmlformats.org/spreadsheetml/2006/main">

    <x:workbookPr defaultThemeVersion="124226" />
    <mc:AlternateContent xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006">
        <mc:Choice Requires="x15">
            <x15ac:absPath xmlns:x15ac="http://schemas.microsoft.com/office/spreadsheetml/2010/11/ac" url="{path}" />
        </mc:Choice>
    </mc:AlternateContent>
    <x:bookViews>
        <x:workbookView xWindow="240" yWindow="90" windowWidth="23580"  windowHeight="10110" />
    </x:bookViews>
    <x:sheets>
        <x:sheet name="PRINT" sheetId="1" r:id="rId1" />
        <x:sheet name="PRINT2" sheetId="4" r:id="rId2" />
        <x:sheet name="Data" sheetId="5" state="veryHidden" r:id="rId3" />
        <x:sheet name="PRINT3" sheetId="6" r:id="rId4" />
    </x:sheets>
    <x:definedNames>
        <x:definedName name="Measures">Books!$C</x:definedName>
        <x:definedName name="_xlnm.Print_Area" localSheetId="0">PRINT!$A:$G</x:definedName>
    </x:definedNames>
    <x:calcPr calcId="152511" calcMode="manual" calcOnSave="0" />
    <x:oleSize ref="A1:G25" />
</x:workbook>

所以我会试一试最好的猜测。
