Method Detail

getAttributeValue

String getAttributeValue(String name)

Return value of attribute with given name and no namespace.

getPITarget

String getPITarget()
                   throws IllegalStateException

Return PITarget from Processing Instruction (PI) as defined in XML 1.0 Section 2.6 Processing Instructions [16] PI ::= '<?' PITarget (S (Char* - (Char* '?>' Char*)))? '?>'

Throws:

IllegalStateException

getPIData

String getPIData()
                 throws IllegalStateException

Return everything past PITarget and S from Processing Instruction (PI) as defined in XML 1.0 Section 2.6 Processing Instructions [16] PI ::= '<?' PITarget (S (Char* - (Char* '?>' Char*)))? '?>'

NOTE: if there is no PI data it returns empty string.

Throws:

IllegalStateException

getRequiredAttributeValue

String getRequiredAttributeValue(String name)
                                 throws IOException,
                                        XmlPullParserException

Read attribute value and return it or throw exception if current element does not have such attribute.

Throws:

IOException

XmlPullParserException

getRequiredAttributeValue

String getRequiredAttributeValue(String namespace,
                               String name)
                                 throws IOException,
                                        XmlPullParserException

Read attribute value and return it or throw exception if current element does not have such attribute.

Throws:

IOException

XmlPullParserException

getRequiredElementText

String getRequiredElementText(String namespace,
                            String name)
                              throws IOException,
                                     XmlPullParserException

Read the text of a required element and return it or throw exception if required element is not found. Useful for getting the text of simple elements such as johndoe. Assumes that parser is just before the start tag and leaves the parser at the end tag. If the text is nil (e.g. ), then a null will be returned.

Throws:

IOException

XmlPullParserException

isNil

boolean isNil()
              throws IOException,
                     XmlPullParserException

Is the current tag nil? Checks for xsi:nil="true".

Throws:

IOException

XmlPullParserException

matches

boolean matches(int type,
              String namespace,
              String name)
                throws XmlPullParserException

Tests if the current event is of the given type and if the namespace and name match. null will match any namespace and any name. If the test passes a true is returned otherwise a false is returned.

Throws:

XmlPullParserException

nextStartTag

void nextStartTag()
                  throws XmlPullParserException,
                         IOException

Throws:

XmlPullParserException

IOException

nextStartTag

void nextStartTag(String name)
                  throws XmlPullParserException,
                         IOException

combine nextTag(); pp.require(XmlPullParser.START_TAG, null, name);

Throws:

XmlPullParserException

IOException

nextStartTag

void nextStartTag(String namespace,
                String name)
                  throws XmlPullParserException,
                         IOException

combine nextTag(); pp.require(XmlPullParser.START_TAG, namespace, name);

Throws:

XmlPullParserException

IOException

nextEndTag

void nextEndTag()
                throws XmlPullParserException,
                       IOException

Call parser nextTag() and check that it is END_TAG, throw exception if not.

Throws:

XmlPullParserException

IOException

nextEndTag

void nextEndTag(String name)
                throws XmlPullParserException,
                       IOException

combine nextTag(); pp.require(XmlPullParser.END_TAG, null, name);

Throws:

XmlPullParserException

IOException

nextEndTag

void nextEndTag(String namespace,
              String name)
                throws XmlPullParserException,
                       IOException

combine nextTag(); pp.require(XmlPullParser.END_TAG, namespace, name);

Throws:

XmlPullParserException

IOException

nextText

String nextText(String namespace,
              String name)
                throws IOException,
                       XmlPullParserException

Read text content of element ith given namespace and name (use null namespace do indicate that nemspace should not be checked)

Throws:

IOException

XmlPullParserException

skipSubTree

void skipSubTree()
                 throws XmlPullParserException,
                        IOException

Skip sub tree that is currently porser positioned on.
NOTE: parser must be on START_TAG and when funtion returns parser will be positioned on matching END_TAG This is typically optimized internally by parser but the logic should follow this: pp.require(XmlPullParser.START_TAG, null, null); int level = 1; while(level > 0) { int eventType = pp.next(); if(eventType == XmlPullParser.END_TAG) { --level; } else if(eventType == XmlPullParser.START_TAG) { ++level; } }

Throws:

XmlPullParserException

IOException
