As default it performs + well-formed parsing,(syntax checks and checks of well-formed + constraints). Optionally one can also use xmerl as a validating + parser,(validate according to referenced DTD and validating + constraints). By means of for example the xmerl_xs module it is + possible to transform the parsed result to other formats, + e.g. text, HTML, XML etc.</p> + </section> + + <section> + <title>Overview</title> + <p>This document does not give an introduction to XML. There + are a lot of books available that describe XML from + different views. At the <url href="http://www.w3.org">www.W3.org</url> site you will find + the <url href="http://www.w3.org/TR/REC-xml/">XML 1.0 specification</url> and other related specs. One site were + you can find tutorials on XML and related specs is <url href="http://www.zvon.org">ZVON.org</url>.</p> + <p>However, here you will find some examples of how to use + and to what you can use xmerl. A detailed description of the + user interface can be found in the reference manual.</p> + <p>There are two known shortcomings in xmerl:</p> + <list type="bulleted"> + <item>It cannot retrieve external entities on the Internet + by a URL reference, only resources in the local file + system.</item> + <item>xmerl can parse Unicode encoded data. But, it fails + on tag names, attribute names and other mark-up names that + are encoded Unicode characters not mapping on ASCII.</item> + </list> + <p>By parsing an XML document you will get a record, + displaying the structure of the document, as return + value. The record also holds the data of the document. xmerl + is convenient to use in for instance the following scenarios:</p> + <p>You need to retrieve data from XML documents. Your + Erlang software can handle information from the XML document + by extracting data from the data structure received by + parsing.</p> + <p>It is also possible to do further processing of parsed + XML with xmerl. If you want to change format of the XML + document to for instance HTML, text or other XML format you + can transform it. There is support for such transformations + in xmerl.</p> + <p>One may also convert arbitrary data to XML. So it for + instance is easy to make it readable by humans. In this case + you first create xmerl data structures out of your data, then + transform it to XML. </p> + <p>You can find examples of these three examples of usage + below.</p> + </section> + </section> + + <section> + <title>xmerl User Interface Data Structure</title> + <p>The following records used by xmerl to save the parsed + data are defined in <c>xmerl.hrl</c></p> + <p>The result of a successful parsing is a tuple + <c>{DataStructure,M}</c>. <c>M</c> is the XML production Misc, + which is the mark-up that comes after the element of the + document. It is returned "as is". <c>DataStructure</c> is an + <c>xmlElement</c> record, that among others have the fields + <c>name</c>, <c>parents</c>, <c>attributes</c> and + <c>content</c> like:</p> + <pre> +#xmlElement{name=Name, + ... + parents=Parents, + ... + attributes=Attrs, + content=Content, + ...} </pre> + <p>The name of the element is found in the <c>name</c> + field. In the <c>parents</c> field is the names of the parent + elements saved. Parents is a list of tuples where the first + element in each tuple is the name of the parent element. The + list is in reverse order.</p> + <p>The record <c>xmlAttribute</c> holds the name and value of + an attribute in the fields <c>name</c> and <c>value</c>. All + attributes of an element is a list of xmlAttribute in the + field <c>attributes</c> of the xmlElement record. + </p> + <p>The <c>content</c> field of the top element is a list of + records that shows the structure and data of the document. If + it is a simple document like: </p> + <pre> +<?xml version="1.0"?> +<dog> +Grand Danois +</dog> </pre> + <p>The parse result will be:</p> + <pre> +#xmlElement{name = dog, + ... + parents = [], + ... + attributes = [], + content = [{xmlText,[{dog,1}],1,[],"\ +Grand Danois\ +",text}], + ... + } </pre> + <p>Where the content of the top element is: + <c>[{xmlText,[{dog,1}],1,[],"\ Grand Danois\ ",text}]</c>. Text will be returned in <c>xmlText</c> records. Though, + usually documents are more complex, and the content of the top + element will in that case be a nested structure with + xmlElement records that in turn may have complex content. All of + this reflects the structure of the XML document.</p> + <p>Space characters between mark-up as <c>space</c>, + <c>tab</c> and <c>line feed</c> are normalized and returned as + xmlText records.</p> + + <section> + <title>Errors</title> + <p>An unsuccessful parse results in an error, which may be a + tuple <c>{error,Reason}</c> or an exit: + <c>{'EXIT',Reason}</c>. According to the XML 1.0 standard + there are <c>fatal error</c> and <c>error</c> situations. The + fatal errors <em>must</em> be detected by a conforming parser + while an error <em>may</em> be detected. Both categories of + errors are reported as fatal errors by this version of xmerl, + most often as an exit.</p> + </section> + </section> + + <section> + <title>Getting Started</title> + <p>In the following examples we use the XML file + "motorcycles.xml" and the corresponding DTD + "motorcycles.dtd". motorcycles.xml looks like: + <marker id="motorcyclesxml"></marker> +</p> + <codeinclude file="motorcycles.txt" tag="" type="none"></codeinclude> + <p>and motorcycles.dtd looks like: </p> + <codeinclude file="motorcycles_dtd.txt" tag="" type="none"></codeinclude> + <p>If you want to parse the XML file motorcycles.xml you run + it in the Erlang shell like:</p> + <pre> +3> {ParsResult,Misc}=xmerl_scan:file("motorcycles.xml"). +{{xmlElement,motorcycles, + motorcycles, + [], + {xmlNamespace,[],[]}, + [], + 1, + [], + [{xmlText,[{motorcycles,1}],1,[],"\ + ",text}, + {xmlElement,bike, + bike, + [], + {xmlNamespace,[],[]}, + [{motorcycles,1}], + 2, + [{xmlAttribute,year,[],[],[],[]|...}, + {xmlAttribute,color,[],[],[]|...}], + [{xmlText,[{bike,2},{motorcycles|...}], + 1, + []|...}, + {xmlElement,name,name,[]|...}, + {xmlText,[{...}|...],3|...}, + {xmlElement,engine|...}, + {xmlText|...}, + {...}|...], + [], + ".", + undeclared}, + ... + ], + [], + ".", + undeclared}, + []} +4> </pre> + <p>If you instead receives the XML doc as a string you can + parse it by <c>xmerl_scan:string/1</c>. Both file/2 and string/2 + exists where the second argument is a list of options to the + parser, see the <seealso marker="xmerl_scan">reference manual</seealso>.</p> + </section> + + <section> + <title>Example: Extracting Data From XML Content</title> + <p>In this example consider the situation where you want to + examine a particular data in the XML file. For instance, you + want to check for how long each motorcycle have been recorded.</p> + <p>Take a look at the DTD and observe that the structure of an + XML document that is conformant to this DTD must have one + motorcycles element (the root element). The motorcycles element + must have at least one bike element. After each bike element it + may be a date element. The content of the date element is + #PCDATA (Parsed Character DATA), i.e. raw text. Observe that if + #PCDATA must have a <c><![CDATA["<"]]></c> or a <c><![CDATA["&"]]></c> character it must + be written as <c><![CDATA["<"]]></c> and <c><![CDATA["&"]]></c> + respectively. Also other character entities exists similar to + the ones in HTML and SGML.</p> + <p>If you successfully parse the XML file with the validation + on as in: + <c>xmerl_scan:file('motorcycles.xml',[{validation,true}])</c> + you know that the XML document is valid and has the structure + according to the DTD.</p> + <p>Thus, knowing the allowed structure it is easy to write a + program that traverses the data structure and picks the + information in the xmlElements records with name date.</p> + <p>Observe that white space: each space, tab or line feed, + between mark-up results in an xmlText record.</p> + <p></p> + </section> + + <section> + <title>Example: Create XML Out Of Arbitrary Data</title> + <p>For this task there are more than one way to go. The "brute + force" method is to create the records you need and feed your + data in the content and attribute fields of the appropriate + element.</p> + <p>There is support for this in xmerl by the "simple-form" + format.

For more details see the xmerl_xs <url href="xmerl_xs_examples.html">tutorial</url>.</p> + <p>Now, back to the example where we wanted to make the output + more arranged. With the template:</p> + <pre> +template(E = #xmlElement{name='motorcycles'}) -> + [ "<head>\ +<title>motorcycles</title>\ +</head>\ +", + "<body>\ +", +\011 "<h1>Used Motorcycles</h1>\ +", +\011 "<ul>\ +", +\011 remove_duplicates(value_of(select("bike/name/manufacturer",E))), +\011 "\ +</ul>\ +", +\011 sort_by_manufacturer(xslapply(fun template/1, E)), + "</body>\ +", +\011 "</html>\ +"]; </pre> + <p>We match on the top element and embed the inner parts in an + HTML body. Then we extract the string values of all motorcycle + brands, sort them and removes duplicates by + <c>remove_duplicates(value_of(select("bike/name/manufacturer", E)))</c>. We also process the substructure of the top element + and pass it to a function that sorts all motorcycle information + by brand according to the task formulation in the beginning of + this example.</p> + <p>The next template matches on the <c>bike</c> element:</p> + <pre> +template(E = #xmlElement{name='bike'}) -> + {value_of(select("name/manufacturer",E)),["<dt>",xslapply(fun template/1,select("name",E)),"</dt>", + "<dd><ul>\ +", + "<li style="color:green">Manufacturing year: ",xslapply(fun template/1,select("@year",E)),"</li>\ +", + "<li style="color:red">Color: ",xslapply(fun template/1,select("@color",E)),"</li>\ +", + "<li style="color:blue">Shape : ",xslapply(fun template/1,select("@condition",E)),"</li>\ +", + "</ul></dd>\ +"]}; </pre> + <p>This creates a tuple with the brand of the motorcycle and + the output format. We use the brand name only for sorting + purpose. We have to end the template function with the "built + in clause" <c>template(E) -> built_in_rules(fun template/1, E).</c></p> + <p>The entire program is motorcycles2html.erl:</p> + <codeinclude file="motorcycles2html.erl" tag="" type="erl"></codeinclude> + <p>If we run it like this: + <c>motorcycles2html:process_to_file('result_xs.html', 'motorcycles2.xml').</c> The result will be <url href="result_xs.html">result_xs.html</url>. When the + input file is of the same structure as the previous + "motorcycles" XML files but it has a little more 'bike' + elements and the 'manufacturer' elements are not in order.</p> + </section> +</chapter> + diff --git a/lib/xmerl/doc/src/xmerl_xs_examples.html b/lib/xmerl/doc/src/xmerl_xs_examples.html new file mode 100644 index 0000000000..aaa3bc5033 --- /dev/null +++ b/lib/xmerl/doc/src/xmerl_xs_examples.html @@ -0,0 +1,291 @@ + +<meta http-equiv="Context-Type" content="text/html;
