# Obsolete Members for QDomDocument

The following members of class QDomDocument are obsolete. They are provided to keep old source code working. We strongly advise against using them in new code.

## Public Functions

`(obsolete)` bool | setContent(QXmlInputSource *source, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)
`(obsolete)` bool | setContent(QIODevice *dev, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

## Member Function Documentation

### bool QDomDocument::setContent(QXmlInputSource *source, bool namespaceProcessing, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

This function reads the XML document from the QXmlInputSource source, returning true if the content was successfully parsed; otherwise returns `false`.

This function was introduced in Qt 4.5.

### bool QDomDocument::setContent(QIODevice *dev, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

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.

### bool QDomDocument::setContent(QXmlInputSource *source, QXmlReader *reader, QString *errorMsg = nullptr, int *errorLine = nullptr, int *errorColumn = nullptr)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This is an overloaded function.

This function reads the XML document from the QXmlInputSource source and parses it with the QXmlReader reader, returning true if the content was successfully parsed; otherwise returns `false`.

This function doesn't change the features of the reader. If you want to use certain features for parsing you can use this function to set up the reader appropriately.
