Я написал функцию в одном из моих угловых проектов для замены тега другим тегом в XML-файле. Первый параметр - это HTMLElement, второй - searchTag, а третий - replaceTag.
replaceTagWith(xmlCode: HTMLElement, findTag: string, replaceTag: string) {
// Initializing variables
let exists: boolean = true;
let processed: boolean = false;
while (exists) {
let sourceTags = xmlCode.querySelector(findTag);
// If findTag exists
if (sourceTags) {
// Setting processed flag
processed = true;
// Creating replace tag and setting the textcontent
let targetTag = document.createElement(replaceTag);
targetTag.innerHTML = sourceTags.innerHTML;
// Finding attributes of the tags to be replaced
let tagAttributes = sourceTags.attributes;
let attrLength = tagAttributes.length;
// If there is attributes
if (attrLength) {
for (let j = 0; j < attrLength; j++) {
// Setting the attribute of replace tag
targetTag.setAttribute(tagAttributes[j].name, tagAttributes[j].value);
}
}
// Appending the target tag just before the source tag
sourceTags.parentNode.insertBefore(targetTag, sourceTags);
// Removing findTag
sourceTags.parentNode.removeChild(sourceTags);
} else {
exists = false;
}
}
Эта функция хорошо работает, когда я заменяю тег <title> на <sec-title>. Вот вызов функции ..
const parser = new DOMParser();
const xml = parser.parseFromString(this.xmlData, 'application/xml');
let xmlCode: any = xml.documentElement;
this.replaceTagWith(xmlCode, 'title', 'sec-title');
результат будет таким:
<sec-title xmlns="http://www.w3.org/1999/xhtml">What is Child Protection<named-content xmlns="http://www.w3.org/1999/xhtml" content-type="index" name="default" a-level="child protection" b-level="definition of" c-level="" d-level="" e-level="" format="" range="" see="" see-also=""></named-content> in Humanitarian Action? </sec-title>
Но проблема в том, что когда я пытаюсь заменить <sec-title> на <title>,результат, показывающий:
<title xmlns="http://www.w3.org/1999/xhtml">What is Child Protection<named-content xmlns="http://www.w3.org/1999/xhtml" content-type="index" name="default" a-level="child protection" b-level="definition of" c-level="" d-level="" e-level="" format="" range="" see="" see-also=""></named-content> in Humanitarian Action? </title>
теги html (здесь <named-content>) внутри <title> заменяются на <named-content>
Это часть xml, с которой я работаю ..

Чтобы отобразить этот код в более широком формате, сначала я заменил тег <title> на <sec-title>, и он работает нормально. Наконец, на этапе экспорта xml я заменил обратно <sec-title> на <title>. Вот этап, на котором возникает проблема ...
