class QXmlSchema ¶

QXmlSchema(other)

param other

QXmlSchema

Constructs an invalid, empty schema that cannot be used until load() 被调用。

构造 QXmlSchema that is a copy of other . The new instance will share resources with the existing schema to the extent possible.

PySide2.QtXmlPatterns.QXmlSchema. documentUri ( ) ¶

返回类型

QUrl

Returns the document URI of the schema or an empty URI if no schema has been set.

PySide2.QtXmlPatterns.QXmlSchema. isValid ( ) ¶

返回类型

bool

Returns true if this schema is valid. Examples of invalid schemas are ones that contain syntax errors or that do not conform the W3C XML Schema specification.

PySide2.QtXmlPatterns.QXmlSchema. load ( source [ , documentUri=QUrl() ] ) ¶

参数

• source – QIODevice

• documentUri – QUrl

返回类型

bool

PySide2.QtXmlPatterns.QXmlSchema. load ( data [ , documentUri=QUrl() ] ) ¶

参数

• data – QByteArray

• documentUri – QUrl

返回类型

bool

PySide2.QtXmlPatterns.QXmlSchema. load ( source ) ¶

参数

source – QUrl

返回类型

bool

设置此 QXmlSchema to a schema loaded from the source URI.

若模式 is invalid , false 被返回且行为未定义。

范例：

QUrl url("http://www.schema-example.org/myschema.xsd");
QXmlSchema schema;
if (schema.load(url) == true)
    qDebug() << "schema is valid";
else
    qDebug() << "schema is invalid";

PySide2.QtXmlPatterns.QXmlSchema. messageHandler ( ) ¶

返回类型

QAbstractMessageHandler

Returns the message handler that handles compile and validation messages for this QXmlSchema .

PySide2.QtXmlPatterns.QXmlSchema. namePool ( ) ¶

返回类型

QXmlNamePool

Returns the name pool used by this QXmlSchema for constructing names . There is no setter for the name pool, because mixing name pools causes errors due to name confusion.

PySide2.QtXmlPatterns.QXmlSchema. networkAccessManager ( ) ¶

返回类型

QNetworkAccessManager

Returns the network manager, or 0 if it has not been set.

setNetworkAccessManager()

PySide2.QtXmlPatterns.QXmlSchema. setMessageHandler ( handler ) ¶

参数

handler – QAbstractMessageHandler

改变 message handler for this QXmlSchema to handler . The schema sends all compile and validation messages to this message handler. QXmlSchema 未拥有所有权对于 handler .

Normally, the default message handler is sufficient. It writes compile and validation messages to stderr . The default message handler includes color codes if stderr can render colors.

当 QXmlSchema calls message() , the arguments are as follows:

message() argument	Semantics
QtMsgType type	Only QtWarningMsg and QtFatalMsg are used. The former identifies a warning, while the latter identifies an error.
const QString & description	An XHTML document which is the actual message. It is translated into the current language.
const QUrl &identifier	Identifies the error with a URI, where the fragment is the error code, and the rest of the URI is the error namespace.
const QSourceLocation & sourceLocation	Identifies where the error occurred.

PySide2.QtXmlPatterns.QXmlSchema. setNetworkAccessManager ( networkmanager ) ¶

参数

networkmanager – QNetworkAccessManager

将网络管理器设为 manager . QXmlSchema 未拥有所有权对于 manager .

PySide2.QtXmlPatterns.QXmlSchema. setUriResolver ( resolver ) ¶

参数

resolver – QAbstractUriResolver

将 URI 解析器设为 resolver . QXmlSchema 未拥有所有权对于 resolver .

uriResolver()

PySide2.QtXmlPatterns.QXmlSchema. uriResolver ( ) ¶

返回类型

QAbstractUriResolver

Returns the schema’s URI resolver. If no URI resolver has been set, Qt XML Patterns will use the URIs in schemas as they are.

The URI resolver provides a level of abstraction, or polymorphic URIs . A resolver can rewrite logical URIs to physical ones, or it can translate obsolete or invalid URIs to valid ones.

When Qt XML Patterns calls resolve() the absolute URI is the URI mandated by the schema specification, and the relative URI is the URI specified by the user.
