Inherited by IpeImlParser.
This is the base class for Ipe's XML parser. It only provides some utility functions for parsing tags and PCDATA. Derived classes implement the actual parsing using recursive descent parsers---after experimenting with various schemes for XML parsing, this seems to work best for Ipe.
Tag names and attribute names must consist of ASCII letters only. Only entities for '&', '<', and '>' are recognized.
| IpeXmlParser::IpeXmlParser | ( | IpeDataSource & | source | ) |
Construct with a data source.
| IpeXmlParser::~IpeXmlParser | ( | ) | [virtual] |
Virtual destructor, so one can destroy through pointer.
| IpeString IpeXmlParser::ParseToTag | ( | ) | [protected] |
Parse whitespace and the name of a tag.
Like ParseToTagX, but silently skips over all tags whose name starts with "x-"
| IpeString IpeXmlParser::ParseToTagX | ( | ) | [protected] |
Parse whitespace and the name of a tag.
If the tag is a closing tag, skips > and returns with stream after that. Otherwise, returns with stream just after the tag name.
| bool IpeXmlParser::ParseAttributes | ( | IpeXmlAttributes & | attr, | |
| bool | qm = false | |||
| ) | [protected] |
Parse XML attributes.
Returns with stream just after >. Caller can check whether the tag ended with a / by checking attr.Slash().
Parse PCDATA.
Checks whether the data is terminated by </tag>, and returns with stream past the >.
