在 gDocs 中使用 gApp 脚本将光标移动到选择和“删除下一行”

Question

我曾尝试使用谷歌应用脚​​本删除谷歌文档的标题和正文部分中的某些段落...但是，如果该段落是一个部分中的最后一个段落，则会出现异常：不能删除文档部分的最后一段。

而这正是我要删除的段落。

我已尝试将该段落与前一段合并，但它不起作用 - 该段落仍然存在。

实现这一目标的唯一有效方法是手动删除段落，方法是将光标放在上一行的末尾并按“前进”删除。这会毫无例外地删除下一行等...但是我需要使用应用程序脚本自动执行此操作 - 所以我问有没有办法在脚本中搜索一个元素，然后从该点模拟按下删除？这更像是一种 hack，但看不到另一种方法？

一个例子可能是：

var foundElement = body.findText("Dialogue");

while (foundElement != null) {
  // Get the text object from the element
  var foundText = foundElement.getElement().asText();

  // Where in the element is the found text?
  var start = foundElement.getStartOffset();
  var end = foundElement.getEndOffsetInclusive();  

 //PSUEDO CODE PRESS FORWARD DELETE TWICE FROM the **end** of the search phrase...
 end.pressdelete(twice)       
}

更新：

我可以通过遍历文档中的所有标题来删除标题段落 - 显然，可以有多个...

对话后我仍然无法删除表格中的空段落（屏幕截图 2）...

var p = d.getBody().getParent(); 
  var headers = [];
  var footers = [];
  // let's loop through all the child elements in the document including headers and footers etc...
  for ( var i = 0; i < p.getNumChildren(); i += 1 ) {
    var t = p.getChild(i).getType();
    if ( t === DocumentApp.ElementType.BODY_SECTION ) continue; // not interested in the body    
    if ( t === DocumentApp.ElementType.HEADER_SECTION ) {
      //OLD CODE FOR FIRST HEADER
      if (headers.length > -1) {
        headers.push(p.getChild(i).asHeaderSection())
      }      
      var h = p.getChild(i).asHeaderSection().getText();      
    } else if ( t === DocumentApp.ElementType.FOOTER_SECTION ) {
      var f = p.getChild(i).asFooterSection().getText();      
    }
  } 


  function cleanHeaders(p) {

    p.forEach(function(h, j, ar) {

      var para = h.getParagraphs();

      para.forEach(function(e, i, arr) {
        var children = e.getNumChildren()
        //Logger.log("::Children:: " + children);
        if (children < 1) {
          var t = e.getText();
          var type = e.getType();      
          var parent = e.getParent();
          var pChildren = parent.getNumChildren();
          var childIndex = parent.getChildIndex(e);
          //Logger.log("::Element::" + e + " ::Number:: " + i + " ::Type:: " + type + " ::Text:: " + t + " ::Children:: " + children + " ::Parent:: " + parent + " ::ParentChildren:: " + pChildren + " ::childIndex:: " + childIndex);

          for ( var i = 0; i < parent.getNumChildren(); i += 1 ) {
            Logger.log(parent.getChild(i));
            if (i != 0) {
              parent.getChild(i).asParagraph().merge();
            }
          } 

          if (parent != 'DocumentBodySection' && parent != 'HeaderSection') {
            //e.getPreviousSibling().merge();
          }          
        }        
      });       
    });
  }

  Logger.log("HEADERS: " + headers.length);  
  cleanHeaders(headers);

作为Can't remove the last paragraph 的解决方法，您可以插入一个额外的虚拟段落

示例：

function myFunction() {
  var body = DocumentApp.getActiveDocument().getBody();
  body.appendParagraph('');
  var foundElement = body.findText("TargetText at end of line");
  while (foundElement != null) {
    var foundText = foundElement.getElement().asText();
    var paragraph = foundText.getParent();
    paragraph.removeFromParent();
    foundElement = body.findText("TargetText at end of line");    
  }
}

如果要删除多个部分的最后一段，可以实现catch..try语句：

function myFunction() {
  var body = DocumentApp.getActiveDocument().getBody();
  var foundElement = body.findText("TargetText at end of line");
  while (foundElement != null) {
    var foundText = foundElement.getElement().asText();
    var paragraph = foundText.getParent();
    var parent = paragraph.getParent();
    try{
      paragraph.removeFromParent();
    }catch(err){
      body.appendParagraph('');
    }
    foundElement = body.findText("TargetText at end of line");    
  }
}

要删除标题和正文foundElement 之后的段落，包括表格，您可以使用以下代码：

function myFunction() {
  var body = DocumentApp.getActiveDocument().getBody();
  var foundElement = body.findText("TargetText at end of line");
  while (foundElement != null) {
    var foundText = foundElement.getElement().asText();
    var paragraph = foundText.getParent();
    var nextParagraph = paragraph.getNextSibling();
    var parent = paragraph.getParent();
    if(nextParagraph!= null && nextParagraph.getType()=="PARAGRAPH"){
      try{
        nextParagraph.removeFromParent();
      }catch(err){
        var dummyParagraph = body.appendParagraph('');
        nextParagraph.removeFromParent();
        dummyParagraph.merge();
      }
    }
    foundElement = body.findText("TargetText at end of line", foundElement);    
  }

  var header = DocumentApp.getActiveDocument().getHeader();
  foundElement = header.findText("TargetText at end of line");
  while (foundElement != null) {
    var foundText = foundElement.getElement().asText();
    var paragraph = foundText.getParent();
    var nextParagraph = paragraph.getNextSibling();
    var parent = paragraph.getParent();
    if(nextParagraph!= null && nextParagraph.getType()=="PARAGRAPH"){
      Logger.log(nextParagraph.asText().getText());
      try{
        nextParagraph.removeFromParent();
      }catch(err){
        var dummyParagraph = header.appendParagraph('');
        nextParagraph.removeFromParent();
        dummyParagraph.merge();
      }
    }
    foundElement = header.findText("TargetText at end of line", foundElement);    
  }  
}
