Excel OpenXml 工作簿类中 xml 元素的特定顺序
本文关键字:元素 定顺序 xml OpenXml 工作簿 Excel | 更新日期: 2023-09-27 17:55:20
我通过OpenXml创建PowerPoint演示文稿。演示文稿的幻灯片中充斥着嵌入的对象。通常,Excel 文档是嵌入的。除了准备要嵌入的图像和文档之外,Excel 还需要另一个信息,在 PowerPoint 中打开文档时应向用户显示该区域。
通过将 OleSize 类添加到工作簿部件,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是否存在,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 将显示一个错误消息对话框,指出该文件已损坏,无法修复。将此元素直接放在 PivotCache OpenXmlElement 之后确实是一种解决方法。现在我体验到,当OpenXmlElement在OleSize之前可用时,Excel也会引发该消息。
我找不到任何关于该特定类的OpenXmlElements订单的必要性的信息。
任何提示都受到高度赞赏。
您对答案中列出的顺序是正确的。在您引用的 OpenXML 规范文档中,有一个 XSD(第 3936 页)用于Workbook
,它表明该顺序确实是强制性的,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,我在这里有一个答案,它显示了将项目添加到文件中正确位置的一种方法。
在深入研究OpenXml规范,第4版之后,我发现了以下信息:
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 }?
没有信息这是保证的还是预期的顺序,但只需几个测试,它看起来很有希望(来自我检查该顺序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:definedNames>
<x:calcPr calcId="152511" calcMode="manual" calcOnSave="0" />
<x:oleSize ref="A1:G25" />
</x:workbook>
所以我会尝试最好的猜测。
