text before xpath to calcuate few more
XPath provides a wide range of functions for various tasks, and here are a few more functions that can be helpful, depending on your specific needs:
It seems like you want to know about XPath functions that are similar to the lower-case() function. The lower-case() function in XPath is used to convert a string to lowercase. Here are 10 XPath functions, along with a brief description of each, that you might find useful:
upper-case(string): This function converts a string to uppercase.
substring(string, start, length): It extracts a substring from a given string, starting at a specified position and with a specified length.
string-length(string): Returns the length (number of characters) of a string.
concat(string1, string2, ...): Combines multiple strings into a single string.
contains(string, substring): Checks if a string contains a specified substring and returns a boolean value (true or false).
starts-with(string, prefix): Tests if a string starts with a given prefix and returns a boolean result.
ends-with(string, suffix): Determines if a string ends with a specified suffix and returns a boolean value.
substring-before(string, separator): Retrieves the substring in a string before a specified separator.
substring-after(string, separator): Retrieves the substring in a string after a specified separator.
normalize-space(string): Removes leading and trailing whitespace characters from a string and replaces multiple consecutive whitespace characters with a single space.
translate(string, from, to): This function replaces characters in a string based on a specified mapping. It replaces characters found in the "from" string with corresponding characters from the "to" string.
substring-count(string, substring): Counts the number of occurrences of a substring within a given string.
string-join(sequence, separator): Joins a sequence of strings into a single string, separated by the specified separator.
normalize-space(string): In addition to removing leading and trailing whitespace, this function also collapses consecutive whitespace characters within the string into a single space.
format-number(number, format): Formats a number according to a specified format pattern, which can be useful for formatting numeric values in a specific way, such as adding commas for thousands or specifying decimal places.
matches(string, pattern): Tests whether a string matches a regular expression pattern and returns a boolean result.
round(number), floor(number), ceiling(number): These functions allow you to round a number to the nearest integer, round down to the nearest integer, or round up to the nearest integer, respectively.
current-date(), current-time(), current-dateTime(): These functions return the current date, time, or date and time in ISO 8601 format, which can be useful for timestamping XML data.
number(string): Converts a string to a number if possible. This function is often used to convert numeric strings to actual numeric values for mathematical operations.
sum(node-set): Calculates the sum of a sequence of numbers contained in a node-set, which can be handy for aggregating numeric values in XML data.
These functions, along with the previously mentioned ones, cover a wide range of common tasks when working with XPath expressions. The choice of function depends on the specific requirements of your XPath query and the transformations you need to perform on XML data.
