Detailed Description

Macro Definition Documentation

◆ forEachXmlChildElement

#define forEachXmlChildElement (   parentXmlElement,
  childElementVariableName 
)
Value:
\
for (auto* childElementVariableName = (parentXmlElement).getFirstChildElement(); \
childElementVariableName != nullptr; \
childElementVariableName = childElementVariableName->getNextElement())

A handy macro to make it easy to iterate all the child elements in an XmlElement.

The parentXmlElement should be a reference to the parent XML, and the childElementVariableName will be the name of a pointer to each child element.

E.g.

XmlElement* myParentXml = createSomeKindOfXmlDocument();
forEachXmlChildElement (*myParentXml, child)
{
if (child->hasTagName ("FOO"))
doSomethingWithXmlElement (child);
}

◆ forEachXmlChildElementWithTagName

#define forEachXmlChildElementWithTagName (   parentXmlElement,
  childElementVariableName,
  requiredTagName 
)
Value:
\
for (auto* childElementVariableName = (parentXmlElement).getChildByName (requiredTagName); \
childElementVariableName != nullptr; \
childElementVariableName = childElementVariableName->getNextElementWithTagName (requiredTagName))

A macro that makes it easy to iterate all the child elements of an XmlElement which have a specified tag.

This does the same job as the forEachXmlChildElement macro, but only for those elements that have a particular tag name.

The parentXmlElement should be a reference to the parent XML, and the childElementVariableName will be the name of a pointer to each child element. The requiredTagName is the tag name to match.

E.g.

XmlElement* myParentXml = createSomeKindOfXmlDocument();
forEachXmlChildElementWithTagName (*myParentXml, child, "MYTAG")
{
// the child object is now guaranteed to be a <MYTAG> element..
doSomethingWithMYTAGElement (child);
}

Function Documentation

◆ parseXML() [1/2]

std::unique_ptr<XmlElement> parseXML ( const String textToParse)

Attempts to parse some XML text, returning a new XmlElement if it was valid.

If the parse fails, this will return a nullptr - if you need more information about errors or more parsing options, see the XmlDocument class instead.

See also
XmlDocument, parseXMLIfTagMatches

◆ parseXML() [2/2]

std::unique_ptr<XmlElement> parseXML ( const File fileToParse)

Attempts to parse some XML text, returning a new XmlElement if it was valid.

If the parse fails, this will return a nullptr - if you need more information about errors or more parsing options, see the XmlDocument class instead.

See also
XmlDocument, parseXMLIfTagMatches

◆ parseXMLIfTagMatches() [1/2]

std::unique_ptr<XmlElement> parseXMLIfTagMatches ( const String textToParse,
StringRef  requiredTag 
)

Does an inexpensive check to see whether the top-level element has the given tag name, and if that's true, does a full parse and returns the result.

If the outer tag doesn't match, or the XML has errors, this will return nullptr;

See also
parseXML

◆ parseXMLIfTagMatches() [2/2]

std::unique_ptr<XmlElement> parseXMLIfTagMatches ( const File fileToParse,
StringRef  requiredTag 
)

Does an inexpensive check to see whether the top-level element has the given tag name, and if that's true, does a full parse and returns the result.

If the outer tag doesn't match, or the XML has errors, this will return nullptr;
