### Question:
MathConverter extends
        AstVisitor<WtNode> { public String getStrippedOutput() { try { return (String) this.go(page.getPage()); } catch (Exception e) { Logger.error(e, "Error parsing page " + this.pageTitle); return ""; } } MathConverter(String wikiText, String name);  MathConverter(String wikiText);  MathConverter(String wikitext, String title, BaseConfig config); boolean isSkipHiddenMath(); void setSkipHiddenMath(boolean skipHiddenMath); List<WikidataLink> getLinks(); List<MathTag> getMathTags(); String getOutput(); String getStrippedOutput(); void visit(WtNode n); void visit(WtNodeList n); void visit(WtUnorderedList e); void visit(WtOrderedList e); void visit(WtListItem item); void visit(EngPage p); void visit(WtText text); void visit(WtWhitespace w); void visit(WtBold b); void visit(WtItalics i); void visit(WtXmlCharRef cr); void visit(WtXmlEntityRef er); void visit(WtUrl wtUrl); void visit(WtExternalLink link); void visit(WtInternalLink link); void visit(WtSection s); void visit(WtParagraph p); void visit(WtHorizontalRule hr); void visit(WtXmlElement e); void visit(WtImageLink n); void visit(WtIllegalCodePoint n); void visit(WtXmlComment n); void visit(WtTable b); void visit(WtTableRow b); void visit(WtTableCell b); void visit(WtTableImplicitTableBody b); void visit(WtTableHeader b); void visit(WtTableCaption b); void visit(WtNewline n); void visit(WtTemplate n); void visit(WtTemplateArgument n); void visit(WtTemplateParameter n); void visit(WtTagExtension n); void visit(WtPageSwitch n); void processTags();  }### Answer:
@Test public void findFormulaFromWikiText() throws Exception { String text = WikiTextUtilsTest.getTestResource("com/formulasearchengine/mathosphere/mlp/gold/eval_dataset_sample.xml"); text = TextExtractorMapper.unescape(text); final MathConverter mathConverter = new MathConverter(text); final String real = mathConverter.getStrippedOutput(); System.out.println(real); }
@Test public void testGo() throws Exception { String wikiText = IOUtils.toString(getClass().getResourceAsStream("legendre_wiki.txt"),"UTF-8"); final MathConverter mathConverter = new MathConverter(wikiText); final String real = mathConverter.getStrippedOutput(); assertThat(real, containsString("Let FORMULA_")); }
