Module : lang.xml
Module Overview
This module provides lang library operations on xml
values defined by the language specification 2019R3.
$anonType$9 |
appendChildren | Append children to an XML if its an element type XML. Error otherwise. New children will be appended at the end of the existing children. |
concat | Concatenates xml and string values. |
copy | Make a deep copy of an XML. |
createComment | Constructs an xml sequence consisting of only a comment item. |
createElement | Constructs an xml sequence consisting of only a new element item. |
createProcessingInstruction | Constructs an xml sequence consisting of only a processing instruction item. |
elements | Selects the elements from an xml value. |
filter | Selects the items from an xml sequence for which a function returns true.
This represents each item in the same way as the |
forEach | Applies a function to each item in an xml sequence.
This represents each item in the same way as the |
fromString | Constructs an xml value from a string.
This parses the string using the |
getAttributes | Returns the map representing the attributes of |
getChildren | Returns the children of |
getContent | Returns the content of a text or processing instruction or comment item. |
getElementName | Get the fully qualified name of the element as a string. Returns an empty string if the XML is not a singleton. |
getItemType | Get the type of a XML as a string. If the XML is singleton, type can be one of 'element', 'text', 'comment' or 'pi'. Returns an empty string if the XML is not a singleton. |
getName | Returns a string giving the expanded name of |
getTarget | Returns the target part of the processing instruction. |
getTextValue | Get the text value of a XML. If the XML is a sequence, concatenation of the text values of the members of the sequence is returned. If the XML is an element, then the text value of the sequence of children is returned. If the XML is a text item, then the text is returned. Otherwise, an empty string is returned. |
isComment | Tests whether an xml value is a singleton consisting of only a comment item. |
isElement | Tests whether an xml value is a singleton consisting of only an element item. |
isEmpty | Check whether the XML sequence is empty. |
isProcessingInstruction | Tests whether an xml value is a singleton consisting of only a processing instruction item. |
isSingleton | Check whether the XML sequence contains only a single element. |
isText | Tests whether an xml sequence consists of zero or more character items. |
iterator | Returns an iterator over the xml items of |
length | Returns number of xml items in |
map | Applies a function to each item in an xml sequence, and returns an xml sequence of the results.
This represents each item in the same way as the |
removeAttribute | Remove an attribute from an XML. |
removeChildren | Remove children matching the given name from an XML. This operation has no effect if the XML is not an element type XML. |
select | Get all the items that are of element type, and matches the given qualified name, in an XML sequence. |
selectDescendants | Searches in children recursively for elements matching the qualified name and returns a sequence containing them all. Does not search within a matched result. |
setAttributes | Sets the attributes to the provided attributes map. |
setChildren | Sets the children of |
setName | Change the name of element |
slice | Returns a subsequence of an xml value. |
strip | Strips the insignificant parts of the an xml value. Comment items, processing instruction items are considered insignificant. After removal of comments and processing instructions, the text is grouped into the biggest possible chunks (i.e. only elements cause division into multiple chunks) and a chunk is considered insignificant if the entire chunk is whitespace. |
