XML Getting Started Tutorial: XSLT-XML/XSLT code example

XSLT is a part of XSL. it is an application of XML and specifies the rules for converting an XML document into another XML document. XSLT is an XML document and a style sheet containing a series of templates. The XSLT processor compares the elements in the input XML document with the templates in the style sheet. if they match, the XSLT in the template is a part of XSL, which is an application of XML, specify the rules for converting an XML document to another XML document.

XSLT is a part of XSL. it is an application of XML and specifies the rules for converting an XML document into another XML document. XSLT is an XML document and a style sheet containing a series of templates. The XSLT processor compares the elements in the input XML document with the templates in the style sheet. if they match, the content of the template is written into an output tree. After processing, the output tree is serialized into an XML document or a document in other formats, such as HTML or rtf.
Several key terms of XSLT

• SOURCE tree: the tree of elements and content in the original document.

• Result tree: the tree of elements and content in the converted document.

• Template rules: the basis of the XSLT style table, divided into two parts: pattern and template. The entire xsl: template element.

• The condition set that matches the elements in the source tree with the pattern rule. Xsl: the value of match in template.

• Template: the part of the result tree to be instantiated when the template rules are applied. Xsl: content in the template element.

• XSLT defines 35 elements in three categories:

• Two root elements

• Xsl: The root element of stylesheet. XSLT is also an XML document. the root element of this document is xsl: stylesheet. All XSLT elements belong to the namespace xmlns: xsl = "http://www.w3.org/1999/XSL/Transform", so all XSLT elements have the xsl prefix. A minimal XSLT document:

• Xsl: the transform element.

• 13 top-level elements can be directly used as child elements of the root element, including:

• Xsl: apply-imports xsl: attribute-set xsl: decimal-format xsl: import xsl: include xsl: key xsl: namespace-alias xsl: output xsl: param xsl: preserve-space xsl: strip-space xsl: template element, used to match elements in XML documents. For example:
       
        
  Match the person element in the XML document. Xsl: variable
       




• 20 instruction elements

• Xsl: apply-imports xsl: apply-template applies the template element to display the specified element value (content ). For example:
        
         
  To display the value of the name element. Xsl: attribute xsl: call-template xsl: choose xsl: comment xsl: copy-of xsl: element xsl: fallback xsl: for-each xsl: if xsl: message xsl: number xsl: otherwise xsl: processing-instruction xsl: text xsl: value-of select element, used to calculate the value (content) of the element ). For example:
         
          
  To obtain the value (content) of the name element in the XML document ). Xsl: variable xsl: when XSLT function
