I know how to get attribute of a tag when I know another attribute of that tag. For example, if I knew hash attribute and needed url attribute, I would do it like thisI have heard that there are XPath string functions, but I did not understand how to use them, or would it even help in this case. The XPath language provides for a core library of functions that deal with: node sets. strings. Booleans. numbers. The following are some examples of XPath functions: Determine the number of articles written by Mr. Jones XPath String Functions - Learn XPath in simple and easy steps starting from basic to advanced concepts with examples including Overview, Expression, Nodes, Element, Attribute, Text, Comment, Absolute Path, Relative Path, Axes, Operators, Wildcard, Predicates.

I. text() isnt a function but a node test. It is used to select all text-node children of the context node. So, if the context node is an element named x, then text() selects all text-node children of x. Other examples: /a/b/c/text(). For example, the contains() function can be used in XPath for a string or varchar data type. Examples 5 and 7 show the use of contains() or the equal () operator for the varchar data type. The XPath string functions are used to manipulate strings of text. With the string functions you can concatenate strings, slice them upAnother use of the string functions is finding nodes that contain a particular substring. For example, if you wanted to analyze your training data and look for training XPath. Contents. Forewords Introduction Statements Search directions Constraints Mathematical functions Service functions Statements and core functions examples Attributes String processing functions Attributes and string functions examples. Example 1 The basic XPath syntax is similar to filesystem addressing. If the path starts with the slash / , then it represents an absolute path to the required element.Example 9 The string-length function returns the number of characters in the string. The following XPath string functions are available in XSLT: concat(string string1 , string string2 In fact, I can think of only a few limited examples where you really need to use the string function. For example, if you insert a Boolean where a string is expected, then the processor will substitute one of the two strings "true" and "false" for the Boolean. The one exception is functions that expect to receive node-sets as arguments. XPath cannot convert strings, Booleans, or numbers to node-sets.
