[deprecated in 6.8] bool QDomDocument::setContent(QIODevice *dev, QString *errorMsg, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload returning ParseResult instead.

This function reads the XML document from the IO device dev, returning true if the content was successfully parsed; otherwise returns false.

No namespace processing is performed.

[deprecated in 6.8] bool QDomDocument::setContent(const QByteArray &buffer, QString *errorMsg, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload returning ParseResult instead.

This function reads the XML document from the byte array buffer, returning true if the content was successfully parsed; otherwise returns false.

No namespace processing is performed.

[deprecated in 6.8] bool QDomDocument::setContent(const QString &text, QString *errorMsg, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload returning ParseResult instead.

This function reads the XML document from the string text, returning true if the content was successfully parsed; otherwise returns false. Since text is already a Unicode string, no encoding detection is performed.

No namespace processing is performed either.

[deprecated in 6.8] bool QDomDocument::setContent(QIODevice *dev, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload taking ParseOptions instead.

This function reads the XML document from the IO device dev, returning true if the content was successfully parsed; otherwise returns false.

[deprecated in 6.8] bool QDomDocument::setContent(QXmlStreamReader *reader, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overload taking ParseOptions instead.

This function reads the XML document from the QXmlStreamReader reader and parses it. Returns true if the content was successfully parsed; otherwise returns false.

If namespaceProcessing is true, the parser recognizes namespaces in the XML file and sets the prefix name, local name and namespace URI to appropriate values. If namespaceProcessing is false, the parser does no namespace processing when it reads the XML file.

If a parse error occurs, the error message is placed in *errorMsg, the line number in *errorLine and the column number in *errorColumn (unless the associated pointer is set to nullptr).

See also QXmlStreamReader.

[deprecated in 6.8] bool QDomDocument::setContent(const QByteArray &data, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

Use the overload taking ParseOptions instead.

This is an overloaded function.

This function parses the XML document from the byte array data and sets it as the content of the document. It tries to detect the encoding of the document as required by the XML specification.

If namespaceProcessing is true, the parser recognizes namespaces in the XML file and sets the prefix name, local name and namespace URI to appropriate values. If namespaceProcessing is false, the parser does no namespace processing when it reads the XML file.

If a parse error occurs, this function returns false and the error message is placed in *errorMsg, the line number in *errorLine and the column number in *errorColumn (unless the associated pointer is set to nullptr); otherwise this function returns true.

If namespaceProcessing is true, the function QDomNode::prefix() returns a string for all elements and attributes. It returns an empty string if the element or attribute has no prefix.

Text nodes consisting only of whitespace are stripped and won't appear in the QDomDocument.

If namespaceProcessing is false, the functions QDomNode::prefix(), QDomNode::localName() and QDomNode::namespaceURI() return an empty string.

Entity references are handled as follows:

• References to internal general entities and character entities occurring in the content are included. The result is a QDomText node with the references replaced by their corresponding entity values.
• References to parameter entities occurring in the internal subset are included. The result is a QDomDocumentType node which contains entity and notation declarations with the references replaced by their corresponding entity values.
• Any general parsed entity reference which is not defined in the internal subset and which occurs in the content is represented as a QDomEntityReference node.
• Any parsed entity reference which is not defined in the internal subset and which occurs outside of the content is replaced with an empty string.
• Any unparsed entity reference is replaced with an empty string.

[deprecated in 6.8] bool QDomDocument::setContent(const QString &text, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is deprecated since 6.8. We strongly advise against using it in new code.

This is an overloaded function.

Use the overloads taking ParseOptions instead.

This function reads the XML document from the string text, returning true if the content was successfully parsed; otherwise returns false. Since text is already a Unicode string, no encoding detection is done.
